no signal from DP when using DP-to-HDMI adapter and HDMI grabber

Other Parts Discussed in Thread: TDA4VM, TDA4VL

HI Ti members

I would like to ask about the display port on TDA4VM EVM.

I used DP with DP-to-HDMI adapter on EVM like below. And it works in PSDK8.6.

1. EVM --> DP-to-HDMI adapter --> portable monitor

2. EVM --> DP-to-HDMI adapter --> HDMI grabber(https://www.avermedia.com/product-detail/GC513)

But after upgrading to PSDK9.0, there is no signal in 2nd case. But it works in 1st case.

Which dts should I modify to use a HDMI grabber?

Best regards

  • Hi Yongsig,

    Are you using vision apps on R5F firmware?

  • Hi Brijesh

    I'm not using it on R5F.

    So I had to disable some of options on 'ti-processor-sdk-linux-adas-j721e-evm-09_00_00_08/board-support/linux-6.1.33+gitAUTOINC+8f7f371be2-g8f7f371be2/arch/arm64/boot/dts/ti/k3-j721e-vision-apps.dtso' like below.

    /*
    &serdes_wiz4 {
    	status = "disabled";
    };
    
    &mhdp {
    	status = "disabled";
    };
    
    &dss {
    	status = "disabled";
    };
    
    &main_i2c1 {
    	status = "disabled";
    };
    */

  • Hi Yongsig,

    I have not seen this kind of issue yet where we see a regression between 8.6 and 9.0 SDK for Linux display. However, we could do some experiments to do some root causing. Looking through device tree between Linux kernel 5.10 and 6.1 that are used for 8.6 and 9.0 SDK respectively, I see a few changes regarding DP. I will list them out here:

    I think above two bullet points would be a good start in troubleshooting what could be different. If they do not resolve the issue, we can dig a little deeper.

    Regards,

    Takuma

  • Hi Takuma

    First, thanks for replying.

    I tried using two options as below. And both failed to resolve this issue.

    -  

    	dp_pwr_3v3: regulator-dp-pwr {
    		compatible = "regulator-fixed";
    		regulator-name = "dp-pwr";
    		regulator-min-microvolt = <3300000>;
    		regulator-max-microvolt = <3300000>;
    		gpio = <&exp4 0 0>; /* P0 - DP0_PWR_SW_EN */
    		enable-active-high;
    
    		/* Always on for now, until dp-connector driver can handle this */
    		regulator-always-on;
    	};

    -  

    	dp_pwr_3v3: regulator-dp-pwr {
    		compatible = "regulator-fixed";
    		regulator-name = "dp-pwr";
    		regulator-min-microvolt = <3300000>;
    		regulator-max-microvolt = <3300000>;
    		gpio = <&exp4 0 GPIO_ACTIVE_HIGH>; /* P0 - DP0_PWR_SW_EN */
    		enable-active-high;
    
    		/* Always on for now, until dp-connector driver can handle this */
    		regulator-always-on;
    	};

    And serdes4 is defined as below

    &serdes4 {
    	torrent_phy_dp: phy@0 {
    		reg = <0>;
    		resets = <&serdes_wiz4 1>;
    		cdns,phy-type = <PHY_TYPE_DP>;
    		cdns,num-lanes = <4>;
    		cdns,max-bit-rate = <5400>;
    		#phy-cells = <0>;
    	};
    };

    So I modified 'max-bit-rate' to 2700 as PSDK8.6

    But it failed as well.

    It's weird because there is no signal when I use Grabber. (As I mentioned above question, it works in PSDK8.6 with the 'regulator-always-on' option)

    When I connect with Grabber, how can I check if DP has read HDCP well or not? or Is it possible to check the HPD(Hot plugged detect) like hdmi?

    Best regards

  • Hi Yongsig,

    Understood. I tried digging through our driver to see if there are anything that stood out. Listing some observations here:

    There has been some changes to how hotplug events are handled in the driver. For example, I see the following irq changed its behavior somewhat between 9.0 SDK: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/gpu/drm/bridge/cadence/cdns-mhdp8546-core.c?h=ti-linux-6.1.y#n2379, and 8.6 SDK: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/gpu/drm/bridge/cadence/cdns-mhdp8546-core.c?h=ti-linux-5.10.y#n2310. An experiment you could try is adding in some printk's to see if you see any differences in behavior between 9.0 and 8.6, and/or try rolling back to the older version if you see some differences.

    Additionally, there is a "cdns,no-hpd" property for the display node that you could add. I think this was used to correct an issue we had with a separate SoC (TDA4VL/J721S2) where the HPD line was incorrectly routed on the board. I think we could use this as a way to troubleshoot whether the HPD is causing issues in our case as well. Details of this can be found in this commit message: https://lore.kernel.org/lkml/20230405142440.191939-3-j-choudhary@ti.com/.

    Otherwise, I also see there is some newly added logic for HDCP here: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/gpu/drm/bridge/cadence/cdns-mhdp8546-core.c?h=ti-linux-6.1.y#n2487. Although, looking through the device tree, I have some doubts on whether hdcp is enabled since I do not see the register for mhdptx-sapb defined in device tree. I also see on the website of the Grabber the following note: "LGP2 PLUS does not support viewing/recording/streaming of HDCP protected signals" which makes me further have suspicion on whether this is causing issues. Nonetheless, you could also add some print statements in this logic to see which path is being taken to troubleshoot this as well.

    --> I'm trying to resolve it using these method.

    I had to add an option in ti_arm64_prune.config.

    - CONFIG_LOCALVERSION="-g8f7f371be2"

    and then build, copy cdns-mhdp8546.ko to sdcard.

    after booting, I put modprobe cdns_mhdp8546, then I've checked if the driver is loaded well via lsmod.

    But the screen via Grabber is not displayed still.

    Do you have another idea?

    Best regards

    Yongsig

  • Hi Yongsig,

    Thank you for trying out the experiments. I'll search for some other things that may be related to this issue.

    One thing that I have found so far that I plan to look into is this E2E thread: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1311552/tda4vm-sdk-9-0-patch-for-edp-to-hdmi-bug/5035861#5035861 

    I will try to look into this today and tomorrow deeper, but if you have some bandwidth on your end, please feel free to review this thread as well. Similarities I see is that it is related to an eDP to HDMI adapter, and the issue is seen during migration between 8.6 and 9.0 versions of SDK.

    However, the hard part is that this thread is for the RTOS driver for display instead of the Linux driver for display, so it is unclear how much this is applicable. But, the patch looks pretty short and deals with the timeout for DP configuration training so you could try to experiment around with this logic in the Linux driver if you do not have other ideas or experiments to try out.

    Regards,

    Takuma

  • Actually, DP-to-HDMI works in my case. But I applied this patch and it failed again. 

    I think I found a clue. In PSDK9.0, I can see this message after booting despite patching 'regulator-always-on'.

    [   21.089904] platform connector: deferred probe pending
    [   21.095058] platform regulator-dp-pwr: deferred probe pending

    Also, the screen shows up well via Grabber in PSDK linux 9.1.0.6 (and there is no regulator message in kernel)

    So I've compared the difference between two versions and then applied it to PSDK Linux 9.0.0.8.

    1. Modified and Added DTS list

    • k3-j721e-vision-apps.dtso

    • k3-j721e-mcu-wakeup.dtsi

    • k3-j721e-main.dtsi

    • k3-j721e-evm-virt-mac-client.dtso

    • k3-j721e-common-proc-board.dts

    • k3-j721e-beagleboneai64.dts

    • k3-j721e-beagleboneai64-dsi-rpi-7inch-panel.dtso(added)

    2. \board-support\linux-6.1.33+gitAUTOINC+8f7f371be2-g8f7f371be2\drivers\gpu\drm\bridges\cadence is same as PSDK Linux 9.1.0.8

    3. packages\ti\drv\dss driver of PSDK rtos 9.0.0.2  is same as PSDK rtos 9.1.0.8.

    After patching all the above things, it failed still.

    But there are differences things between two versions. These are messages from 'dmesg | grep "platform*"'.

    If you have another idea, please let me know.

    Best regards

    Yongsig

  • Hi Yongsig,

    Those messages are a bit concerning. Could you send the full dmesg logs from when you have the HDMI grabber connected.

    And could you also provide details about the DP-to-HDMI adapter? May make sense to see if we can procure the same adapter and HDMI grabber to try to reproduce the issue on our end.

    Regards,

    Takuma

  • Hi Takuma,

    I'm using the DP-to-HDMI from GENDER master company.

    https://naroit.co.kr/product/detail.html?product_no=17&cate_no=26&display_group=1#prdDetail

    It's a Korean company but I believe you can read the specifications on the website.

    First, I attached my dtbs. Please go through them.

    4152.dtb.zip

    after updating dtbs, platform regulator-dp-pwr messages were disappeared.

    Last, I modified drm_dp_mst_hpd_irq function in drm_dp_mst_topology.c as PSDK linux 9.1.0.8.

    I've modified other codes such as amdgpu_dm.c, intel_dp.c and disp.c which are related to 'drm_dp_mst_hpd_irq' to make same as PSDK9.1.0.8. 

    and then copied new driver files as below.

    • drivers/gpu/drm/drm.ko

    But it was failed again.

    Please test by using my dtbs and then if you could recommend a new DP-to-HDMI, I'll test.

    (My DP-to-HDMI is working well in other psdk versions. So I don't think adapter is root cause)

    For more information, I'n using QT libs, so I'm checking the screen with weston.ini

    I copied my weston.ini to /etc/xdg/weston/weston.ini  in sdcard

    [core]

    require-input=false
    
    [shell]

  • Hi Yongsig,

    I ordered the HDMI grabber and obtained a similar DP to HDMI adapter from a co-worker. The grabber should arrive next week Wednesday at the latest.

    As of now, I do not have a good idea as to why this specific combination of device is not working. This looks like a corner case, so I would like to set expectation that debugging this may take some time.

    Regards,

    Takuma

  • Hi Takuma

    I sincerely appreciate you for your help.

    If It's hard to make the same case on your side, please let me know.

    Best regards

    yongsig

  • Hi Yongsig,

    Understood and thank you for your patience.

    Regards,

    Takuma

  • Hi Yongsig,

    I have received the HDMI grabber and doing some initial tests with it. It looks like this issue is very specific with 9.0.0.8 version of the SDK. I tried with the 9.0.1.3 SDK and find that the grabber works fine. You could also test this on your end: https://www.ti.com/tool/download/PROCESSOR-SDK-LINUX-J721E/09.00.01.03.

    Currently looking into what the change was - it will probably take a few days since I will be consulting with some folks in a different timezone.

    Otherwise, a workaround would be to see if you can update your SDK to a newer SDK.

    Regards,

    Takuma

  • Hi, Takuma.

    Thanks for your effort to make the same issue on your side.

    I'll try PSDK Linux 9.0.1.3. I was wondering if I could use PSDK RTOS 9.0.0.8 with PSDK Linux 9.0.1.3.

    Once I tried to run PSDK RTOS 9.0.0.8 with PSDK Linux 9.1.0.6, It failed due to a different memory region.

    And my customer wants to use PSDK RTOS Linux 9.0.0.8 still. If you figure out the root cause, please let me know.

    Best regards

    Yongsig


    [update]

    I tried to run my app in psdk rtos 9.0.0.2 with psdk linux 9.0.1.3 and it runs well.

    Also, I disabled some features in vision_app dts of psdkla 9.0.1.3 not to use r5 display as below.

    /*
    &serdes_wiz4 {
    	status = "disabled";
    };
    
    &mhdp {
    	status = "disabled";
    };
    
    &dss {
    	status = "disabled";
    };
    
    &main_i2c1 {
    	status = "disabled";
    };
    */

    But the displaying issue is the same as before.

    So, I tried to boot using the default psdkla image to see TI wayland on the screen.

    The only things that I modified are vision_app dtbs and uEnv as below.

    # name_overlays_fit=conf-ti_k3-j721e-evm-virt-mac-client.dtbo conf-ti_k3-j721e-vision-apps.dtbo

    Just disabled the last line in the uEnv.txt in BOOT of sdcard.

    I can see the screen from /etc/xdg/weston/weston.ini once I connect to portable monitor via DP-to-HDMI.

    But there is no signal via Grabber.

    Additionally, I can see the Wayland when I use only psdk linux 9.1.0.6.

    How could you see the screen via Grabber in psdk linux 9.0.0.8?

    Best regards

    Yongsig

  • Hi Yongsig,

    Apologies for the confusing wording in my previous post. I was not able to get Grabber to work in PSDK Linux 9.0.0.8. Only on 9.0.1.3 and above, or 8.6 or less versions for PSDK Linux, the Grabber was working -> or, more simply put, I found that only with 9.0.0.8 SDK version the Grabber did not work, and all other versions I have tried so far works.

    Currently trying to understand the differences.

    However, you mention you can get 9.1.0.6 to work. For the customer use case/requirement, would this be a sufficient work around while we root cause the issue for 9.0.0.8?

    Regards,

    Takuma

  • Hi Takuma.

    The customer and our side is already working on PSDK rtos 9.0.0.2 and linux 9.0.0.8. The only problem that we have is on Grabber use case.

    It looks like It's hard to upgrade to 9.1.0.6 now, as you know there are so many updates in TIDL.

    Do we have a test that HPD is working or another physically?

    Best regards

    Yongsig

  • Hi Yongsig,

    Understood that they are working on 9.0.0.8 and it is difficult to upgrade to 9.1.0.6 for TIDL. However, it is also equally difficult to determine which specific patch has made the fix between 9.0.0.8 and 9.1.0.6. I will try to go through and test if there is a specific patch that fixes the issue, but there are a couple thousand changes between 9.0.0.8 and 9.1.0.6 to go through, so please expect that this will take a very long time. It would most likely be faster to port code over to the new SDK version.

    Regards,

    Takuma

  • Hi Yongsig,

    Just as an update, I think I have narrowed down the commits to around 10 commits. Will be testing these commits tomorrow to see if one can fix the HDMI grabber issue.

    Regards,

    Takuma

  • I appreciate your effort.

    I'll wait the update.

    Best regards

    Yongsig

  • Hi Yongsig,

    May take a few more days on this.

    I currently think this commit initially caused the issue: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/commit/?h=ti-linux-6.1.y&id=51404b29a0d264d0ccc3bea29ae3df123aa41c28. But, I think there is a possibility that there are other commits that are affecting the display output.

    Regards,

    Takuma

  • Hi Yongsig,

    It looks like reverting this commit fixes the HDMI grabber on my end:

    • git revert 63672bc1fe1

    In your Linux kernel, could you also do the same and confirm?

    The commit message of the commit to revert is: "HACK: arm64: configs: defconfig: Enable OMAP mailbox"

    Regards,

    Takuma

  • Hi Takuma,

    Thanks for your effort.

    Once I tried to revert it, failed.

    Would you share more details about guidance?

    And If the kernel version is reverted, What driver (ko files) should I update into the Linux file system image?

    Best regards

    Yongsig

  • Hi Yongsig,

    That is probaby due to having some uncommitted changes in the kernel. As the log message says, either commit the changes or stash them. Alternatively, if you are not savvy with git, then you could manually apply below change. It is a one line change, so it should be relatively easy to change.

    0001-Revert-HACK-arm64-configs-defconfig-Enable-OMAP-mail.patch

    The patch changes omap-mailbox.ko.

    Regards,

    Takuma

  • Hi Takuma

    As you know, there is no omap_mailbox.ko in targets basically.

    So I have made a directory and copied omap_mailbox.ko into lib/modules/6.1.33-g8f7f371be2/kernel/drivers/mailbox.

    and then, after booting.

    Loading omap-mailbox.ko failed.

    root@j721e-evm:~#
    

    Do you know what I missed?

    Best regards

    Yongsig

  • Hi Yongsig,

    The patch removes -CONFIG_OMAP2PLUS_MBOX=y from the kernel config. Since it was "y" instead of "m", this used to be built into the kernel. However, we are removing this config, so we need to update the kernel instead of the kernel module. Please remove this line from <PSDK LInux installation directory>/board-support/linux-*/arch/arm64/configs/defconfig and recompile.

    If you are using the top level makefile as documented here, then to build and install the kernel, running "make linux" and "sudo ROOTFS_PART=/path/to/root/partition/of/sd/card make linux_install" should build and install the kernel, kernel modules, and device tree blobs: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/09_01_00_06/exports/docs/linux/Overview_Top_Level_Makefile.html

    Regards,

    Takuma

  • Hi Takuma.

    CONFIG_OMAP2PLUS_MBOX=y has been removed.

    After make, make linux-dtbs, make linux.

    The only file which is changed is omap-mailbox.ko. I don't think I need to copy all kernel files from psdkla/targetNFS to sdcard.

    That's why I asked you what I should copy into sdcard and what I should do more.

     

    As your recommendation, I copied all files in targetNFS in psdkla into sdcard/rootfs.

    But any screen from weston file is not displayed now including a portable monitor.

     

    Best regards

    Yongsig

  • Hi Yongsig,

    That is strange... could you do an experiment then?

    Check out the following commit: "git checkout 9ee794b9509"

    This should be 1 commit before the commit I reverted. I tested on my end just now, but this commit seems to have display working.

    Regards,

    Takuma

  • Hi Takuma

    I succeeded "git revert 63672bc1fe1" and then I checked The only thing that is changed is deconfig.

    After booting, omap-mailbox driver loaded well.

    But, any screen is not displayed.

     

    I'll share my rootfs in sdcard. Could you test using mine? You can download the below link. (password is 1234) 

    - http://119.202.38.9:5000/sharing/R1FrEZz6T

     

    and then I'll attach a new dtbo and uEnv.txt not to use r5f display.

    uEnv_qt.txt
    psdk_setup_file=.psdk_setup
    check_psdk_setup=load mmc 1:1 ${loadaddr} ${psdk_setup_file}

    Please copy them into sdcard before test.

    and then Please let me know if qt screen shows up or not.

    I think It'll be good if we have a meeting using teams or zoom.  I can show my problem in real time.

    My time zone is EST. How about you ? and what do you think?

    Best regards

    Yongsig

  • Hi Yongsig,

    I am currently out of office due to US holiday so I do not have access to my work PC until next Tuesday. I can try reviewing your SD card image when I come back to office.

    In the meantime, could you do also do the experiment where you go back to an older commit as mentioned in my previous post? Hardware and software-wise, we should have the exact same set up, since we have obtained the same HDMI grabber, so it is strange that we are seeing different behaviors.

    Regards,

    Takuma

  • Hi Yongsig,

    Unfortunately, it seems like our company proxy blocks the URL as a suspicious link, so I am unable to test out the image from you.

    On the other hand, were you able to test out the older commit by checking it out? I would like to see whether you can reproduce what I am seeing on my setup where HDMI grabber comes up when I check out commit ID 9ee794b9509.

    Regards,

    Takuma

  • Hi Takuma.

    That link have expired. So I'll share the new link. Could you try downloading again?

    - http://119.202.38.9:5000//sharing/tCvwEdOt0

    I'll try it on commit ID 9ee794b9509. But I can share the test result next week.

    Before trying, I would like to make sure if I should add CONFIG_LOCALVERSION="-g8f7f371be2" option in ti_arm64_prune.config file.

     

    Best regards

    Yongsig do

  • Hi Yongsig,

    I do not have CONFIG_LOCALVERSION set in ti_arm64_prune.config when testing on my setup, so it should not be needed.

    1. What should I fix to build?

    2. What is your default screen ?

    3. What file should I change to diaply using A72 (not R5f)?

    Best regards

    Yongsig

  • Hi Yongsig,

    Please use the target "make linux" and "sudo ROOTFS_PART=</path/to/root/filesystem/of/sd/card> make linux_install" to build and install.

    While using the Linux SDK, default display should be set to A72 instead of R5F, so no changes should be necessary.

    Regards,

    Takuma

  • Hi Takuma.

    I did as you mentioned.

    1. flash sdcard using defualt psdk image in psdk rtos install path.

    - "sudo ./sdk_builder/scripts/mk-linux_sdcard.sh /dev/sdc"

    - "./sdk_builder/scripts/install_to_sdcard.sh"

    2. make linux and then copy to sdcard in psdk linux install path

    - "./setup.sh"

    - "make linux"

    - "sudo ROOTFS_PART=/media/usami/rootfs make linux_install"

    But there is no signal on the monitor. That's why asked about what the default screen was.

    Was it Just console screen or QT screen?

    I don't think there will be any progress if I do this.

    What do you think about we are having an online meeting?

    Best regards

    Yongsig

  • Hi Yongsig,

    Default screen - what I see is default Weston GUI coming up on the monitor that is connected through HDMI to the HDMI grabber, which is then connected to DP through an active HDMI to DP adapter to DP0 port on the TDA4VM EVM.

    I assumed this is exactly the same setup as your setup... however, it seems that is not the case and we cannot reproduce the issue being seen at your setup on our setup. I think you mentioned 9.1 SDK is working in the past, so please port your code to the latest SDK.

    Regards,

    Takuma

    I think R5 core is used for display.

    mhdp driver is for DP, isn't it?

    Best regards

    Yongsig

  • Hi Yongsig,

    Yes, you are right. It does seem like mhdp driver is not getting probed. Is there a device tree overlay in uEnv.txt on your setup by any chance? If SDK default device tree is being built, that would be the only reason I can think of for why DP is not getting probed.

    Otherwise, attached are my dmesg logs that you can check for comparison. I also printed out the kernel version via uname, kmsprint to verify monitor is being detected (and visually, a gray background shows up on the connected monitor), and lsmod output that can also be used as comparison to identify difference between our setups.

    Hope this helps with troubleshooting.

    These are some parts of logs from "sudo ROOTFS_PART=/media/usami/rootfs make linux_install".

    Why '00009-g9ee794b9509d-dirty' of name is following?

    Best regards

    Yongsig

  • Hi Yongsig,

    I found wrong path once I put "sudo ROOTFS_PART=/media/usami/rootfs make linux_install"

    Could I get a clarification of what "wrong path" is? Kernel modules should automatically install under rootfs/lib/modules/<Linux kernel version number>, and kernel should check the correct folder with the kernel modules. "make linux_install" installs dts, kernel, and kernel modules that are all compatible with each other as they are compiled from the same kernel source.

    As you know there is no "/lib/modules/6.1.33-g8f7f371be2-00009-g9ee794b9509d-dirty" folder in sdcard.

    The folder should get created automatically when "make linux_install" is ran.

    Why '00009-g9ee794b9509d-dirty' of name is following?

    "00009-g9ee794b9509d" is the commit ID that we have checked out, "dirty" means there are uncommited changes within your Linux kernel source code.

    Regards,

    Takuma

  • Hi Takuma

    Thanks for your answer.

    As you know, the name of kernel directory in the default SDK image is "6.1.33-g8f7f371be2".

    - default SDK Image link : https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-U6uMjOroyO/09.00.00.08/tisdk-adas-image-j721e-evm.tar.xz

    I though that all kernel files should be overwritten on "sdcard/rootfs/lib/modules/6.1.33-g8f7f371be2"

    Should I remove the original kernel after copying the new kernel ?

    I mean the new kernel is "6.1.33-g8f7f371be2-00009-g9ee794b9509d-dirty".

    And Please check if my sequence is correct or not.

    1. flash the sdcard using default SDK image.(https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-U6uMjOroyO/09.00.00.08/tisdk-adas-image-j721e-evm.tar.xz)

    2. git checkout 9ee794b9509   in <psdk_linux_install_path/board-support/linux-6.1.33+gitAUTOINC+8f7f371be2-g8f7f371be2>

    3. psdk linux install and "setup.sh" and then "make_linux"

    4. "sudo ROOTFS_PART=</path/to/root/filesystem/of/sd/card> make linux_install"

     

    If I use the device trees in the default SDK image, the display will run on R5F not A72.

    If I want to use A72, I think I must use 'mdhp' module in the kernel.

    So that's why I changed some features in k3-j721e-vision-apps.dtso in first trying(not in 9ee794b9509  commit ).

    /* disable below features not to use R5 for display
    &serdes_wiz4 {
    	status = "disabled";
    };
    
    &mhdp {
    	status = "disabled";
    };
    
    &dss {
    	status = "disabled";
    };
    
    &main_i2c1 {
    	status = "disabled";
    };
    */

    I would like to want to make the same environment and kernel image as yours.

     

    Best regards

    Yongsig

  • Hi Yongsig,

    For step 1, it looks like you are downloading just the filesystem which is what would be flashed into the rootfs partition. This leads me to suspect the boot partition is not being modified.

    Please ensure the uEnv.txt in boot partition does not have any overlays set for testing purposes:

    That is, if there is something like name_overlays=k3-j721e-vision-apps.dtso, please delete this line.

    After you can confirm that Linux can detect HDMI grabber, then we should move on to the next step of applying vision-apps overlays and testing with  your application.

    Regards,

    Takuma

  • Hi Takuma

    Of course, I downloaded boot file from this link : https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-U6uMjOroyO/09.00.00.08/boot-adas-j721e-evm.tar.gz

    and then, as you know sdcard have been flashed using ./sdk_builder/scripts/install_to_sdcard.sh.

    These are file list in default boot portion.

    3. psdk linux install and "setup.sh" and then "make_linux"

    4. "sudo ROOTFS_PART=</path/to/root/filesystem/of/sd/card> make linux_install"

    and then should I do next step to check detecting HDMI grabber ? 

    or should I check to detect HDMI grabber before doing next steps?

    Best regards

    Yongsig

  • Hi Yongsig,

    Try removing the name_overlays line altogether for testing purposes, including k3-j721e-evm-virt-mac-client.dtbo. Or, in Linux SDK, there is a different install script which flashes the micro SD card with default Linux image with no ties to RTOS SDK: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/09_02_00_05/exports/docs/linux/Overview/Processor_SDK_Linux_create_SD_card.html#create-sd-card-with-default-images-using-script. Using this to create the image will isolate the issue from any RTOS and vision apps components that could be causing differences in observed behavior between our setup.

    Then do steps 2, 3, and 4. 

    Regards,

    Takuma

  • Hi Takuma

    I did as below sequence.

    1. format sdcard using mk-linux-sdcard.sh

    2. flash sdcard using install-to-sdcard.sh

    3. remove all name_overlays in uEnv.txt

    # Setting the right U-Boot environment variables
    dorprocboot=1
    
    # Name overlays when booting from fit image
    

    4. "make_linux" and "sudo ROOTFS_PART=</path/to/root/filesystem/of/sd/card> make linux_install"

    Thanks for your hard effort. I appreciate your effort. 

    I think the root cause is different from your case even though I have the same environment as you.

    If you have another idea of what I can do, please let me know

  • Hi Takuma,

    I ordered the same one.

    And the test result was FAIL. I don't have any idea what we should do more. 

    Anyway. I appreciate your help with this issue.

    I'll try again as you mentioned. and then I'll close this ticket later. 

    Best regards

  • Hi Yongsig,

    Ok understood. It is very strange that the setup is failing on your end. It looks to me hardware and software versions are all the same between our setups.

    Apologies for not being able to root cause, and I appreciate your patience with this issue.

    Regards,

    Takuma
