Hi TI members:

Our customer board use OSPI boot and load rootfs form eMMC.

And in Linux part, we already have some pinmux settings for our customer board.

Right now, we try to enable our customer's camera with Linux+RTOS 7.0 version. and we meet a issue.

We find there are many pinmux config are different as our settings.

When we first power-on our customer board, our 11c000.pinmux table is version A(this version is our linux pinmux config), as this file.

root@j7-evm:~#

So I compare some situation, and I find the root cause of pinmux table version A and version B is depend on is there a j7-main-r5f0_0-fw in /lib/firmware/ when we reboot.

If I rename or directly delete the /lib/firmware/j7-main-r5f0-0-fw, and then reboot. the pinmux table will always keep on version A.

And I find there are some pinmux table config in psdkra/pdk_jacinto_07_00_00/packages/ti/board/src/j721e_evm/.

Now, I have two questions,

1. Why the remote process didn't load j7-main-r5f0_0-fw when we power-on the board, even I already set below env parameter.

=> setenv rproc_fw_binaries '2 /lib/firmware/j7-main-r5f0_0-fw 3 /lib/firmware/j7-main-r5f0_1-fw 4 /lib/firmware/j7-main-r5f1_0-fw 5 /lib/firmware/j7-main-r5f1_1-fw 6 /lib/firmware/j7-c66_0-fw 7 /lib/firmware/j7-c66_1-fw 8 /lib/firmware/j7-c71_0-fw'
=> setenv dorprocboot 1
=> setenv name_overlays 'k3-j721e-vision-apps.dtbo'
=> saveenv
=> reset

Only when we reboot the board, the process seem load successfully.

2. I study the doc , and try to follow to disable origin addon board pinmux config.

below is my steps:

1. Modify Board_pinmuxConfig function in 'packages/ti/board/src/j721e_evm/board_pinmux.c' file
2. Modify SRCS_COMMON parameter in 'packages/ti/board/src/j721e_evm/src_files_j721e_evm.mk' file, and delete three files(J721E_pinmux_data_info.c J721E_pinmux_data_gesi.c J721E_pinmux_data_gesi_cpsw9g.c)
3. Rebuild board library $ cd psdkra/pdk_jacinto_07_00_00/packages/ti/build 
    $ make -s allclean 
    $ make -s allcores BOARD=j721e_evm 
4. Rebuild Vision_Apps 
    $ cd psdkra/vision_apps 
    $ make vision_apps_clean 
    $ make vision_apps
    $ make linux_fs_install

I flash the new files which in psdkra/targetfs folder to my eMMC rootfs partition.

But the 11c000.pinmux table is still like version B after we reboot the board.

It seem my modify didn't work.

Can you also help to check my steps, did I miss any thing?

Hi Sentinen Chen,

Thanks for all the details. Does the same issue occur when you try with FS on SD card?
I.e booting from SD card & file system also in SD card?

I will try to reproduce this at my end as well but can you also check if this behavior is same with SD
card boot as well & is this a custom board with TDA4 or TDA4 standard EVM?

Best Regards,
Keerthy

Hi Keerthy:

booting from SD card & file system also in SD card?

Ans : I try two way "booting and load file-system form SD card" and "OSPI boot+load rootfs form eMMC" on TI-EVM board, it seem the our customer board's situation didn't happen on TI-EVM board.

but I get one error when I try below steps no matter which boot way.

I got two verison of pinmux table on TI-EVM board, veriosn A is only linux part

1. When I power-on TI-EVM board without /lib/firmware/j7-main-r5f0_0-fw, I can get version A pinmux table.
2. Then I put j7-main-r5f0_0-fw file into /lib/firmware/, and reboot TI-EVM board.
3. After reboot, I can get version B pinmux table.
4. Then I delete the /lib/firmware/j7-main-r5f0_0-fw, and reboot TI-EVM board.
5. After reboot, I can get a almost pinmux like version B, except PIN105 and PIN151. I think it should like version A, not like version B.
6. I shudown-down TI-EVM board first, and then repower-on it. I can get version A pinmux table after boot.

I can't understand why pinmux still keep on linux+j7-main-r5f0_0-fw version even I already delete the j7-main-r5f0_0-fw file.

BTW, our customer board didn't have SD card, so I can't test the SD card flow on our customer board.

disable origin addon board pinmux config in RTOS

Ans: I find there is one file (packages/ti/drv/cpsw/examples/cpsw_apputils/V1/cpsw_board_pinmux.c) also use gJ721E_MainPinmuxDataGesiCpsw9gQsgmii pinmux. After I also disable this part function, and rebuild j7-main-r5f0_0-fw, now I can see most pinmux keep on my linux config when I reboot our customer board.

It is sure that our customer board still can't load j7-main-r5f0_0-fw when first time power-on.

Hi Keerthy:

It just describe we still have the problem that it seem our board still can't load j7-main-r5f0_0-fw at first time power-on our board,

because we still get linux version pinmux table when our board first time power-on even we already have /lib/firmware/j7-main-r5f0_0-fw in rootfs.

Hi Sentinen,

When you execute reboot command the A72 is reset the pinmux memory is still in tact.

So we need to be aware of the possible places where pinmux is done:

1) SPL
2) U-boot
3) Linux
4) R5F Firmwares.

All the above can change the pin configurations. Reboot is not resetting the pin configuration registers.

So when at first you have firmware the config written with that will not be really modified
as the other entities SPL/u-boot/Linux will not be touching them.

Hope i am clear.

Keerthy

==> Sorry, I have some confuse.

I know the pinmux change is not caused by reboot.

My concern always is why j7-main-r5f0_0-fw didn't work normal when our board first-time power-on.

Because I can see main-UART log like below when our board first-time power-on.

4839748 bytes read in 20 ms (230.8 MiB/s)
Load Remote Processor 2 with data@addr=0x80080000 4839748 bytes: Success!

the log show the remote core 2 is already load j7-main-r5f0_0-fw,

what situation will caused like your described that the Linux SPL/u-boot/Linux will not be touching j7-main-r5f0_0-fw?

Hi Sentinen Chen,

I did not understand this. Do you mean even if the firmware is loaded the pin configuration
done by firmware is not seen properly only in the first boot?

Can you share the full log please?

Hi Keerthy:

Please see this log file V3GA_pinmux_diff.txt

In this file, I total boot our customer board and check 11c000.pinmux table three times.

Step 1 : Power on our customer board.

Step 2 : After boot finished, check 11c000.pinmux table first time.

Step 3 : Reboot our customer board in MAIN-UART.

Step 4 : After reboot finished, check 11c000.pinmux table second time

Step 5 : Reboot our customer board in MAIN-UART.

Step 6 : After reboot finished, check 11c000.pinmux table third time

You can find the first time pinumx is different with second time & third time.

This is why I doubt the firmware didn't work normal in first-time power-on our customer board, even we can see the log show that firmware is loaded.

Hi Sentinen-Chen,

I am seeing that there is no delta between boot-2 & boot-3 & I believe any subsequent reboots will not differ.

Here is the delta that i am observing from your log:

So seems like multiple pins are at the reset value in boot-1(First boot). Ex: 0x08214007.

As part of some other debug i had observed that the pinmux from the firmwares were indeed taking effect in the first boot.

Can you please let me know if you have some particular pins that are wrong in the first boot & also where were they supposed
to be set(i.e SPL or u-boot or remoteproc firmware) This will help narrow down the issue if any.

Keerthy

==> Yes, We have some camera related pin's pinmux which need to control in remoteproc firmware,

like some deserializer control pins (GGPIO0_75/GPIO1_19/PIO1_26 ...).

Now I already add one customer_pinmux_data.c in psdkra/pdk_jacinto_07_00_00/packages/ti/board/src/j721e_evm/

and modify packages/ti/board/src/j721e_evm/board_pinmux.c to load oue customer pinmux config.

And for first power-on issue, I also set the same pinmux config into u-boot to make sure each boot can have same pinmux.

Anyway, if we can fix the first power-on issue, then we will only need modify pinmux in one path.

even it maybe can fix my another question (Remote_Service didn't init when run vision_apps_init.sh in first power-on, thread).

Hi Chen,

If you are set the pinmux configuration in the board module, it might not get set on the SPL/uboot prompt. Because Board modules runs on the R5F, so untill R5f firmware gets loaded and board is initializes, you will not see this pinmux setup.

Hi Chen,

Also, i saw that, atleast in vision apps from sdk7.0, it does not setup all the pinmux, supported in the board module. It setup pinmuxes only for the modules it enables, for example, if HDMI output is enabled, then it sets pinmux for vout and i2c modules..

So can you check if the pins that you are using as GPIO are muxed with our functions, if these modules are getting enabled in the vision apps? Then you could disable these modules in vision apps to keep your pinmux values unchanged in uboot..

==> Yes, we hope our RTOS's code can support on QNX together,

So I already add a define to decide which config (our customer board's pinmux, or EVM attend board's pimmux) in RTOS we want to load.

Actually just like you say "untill R5f firmware gets loaded and board is initializes, you will not see this pinmux setup",

Right now, let us confused is why first-time power-on our board, the main-r5f0_0 firmware seem didn't load successfully.

In first-time power-on our board, the pinmux will different with the reboot's pinmux result.

You can reference our earlier three times boot log file.

Hi Chen,

I did not get, why do you think firmware is not getting loaded? Is it by just looking at the pinmux value? Did you run any usecase or vision_apps_init.sh script to confirm it is running?

"Right now, let us confused is why first-time power-on our board, the main-r5f0_0 firmware seem didn't load successfully"

Please note that this firmware main-r5f0_0 will be loaded by uboot, even before Linux starts, so Linux can definitely overwrite the pinmux written by the firmware, is that your observation?

HI Brijesh:

I did not get, why do you think firmware is not getting loaded?
Ans: For this doubt, I see two reason.
1. Remote_Service didn't init when run vision_apps_init.sh in first power-on, thread
2. Pinmux table is different betwen first power-on and reboot time, as this thread discuses.
Please note that this firmware main-r5f0_0 will be loaded by uboot, even before Linux starts, so Linux can definitely overwrite the pinmux written by the firmware, is that your observation?
Ans: No, our observation as below,
Only when our board first power-on, the final pinumx status will be overwrite by Linux.
When we reboot the board, the final pinmux will keep the status which be written by the firmware.
If firmware load steps as you say, then our pinmux should always keep on the status which overwrite by Linux.
One more question, I open one thread to discuess the dorprocboot in uboot & remoteproc load in linux.
Do you think this will be one reason to make different pinmux status on different boot time?

TI__Guru**** 504345 points

Hi Chen,

Lets discuss the issues one by one.

Lets first target pinmux issue.

What i am thinking is

On the first boot, uboot is loading the firmware first and then Linux comes up. So if the both firmware and Linux are trying to set the different pinmux value for the same pin, then on first boot, the pin value you would get is from the Linux.
On the reboot command, i believe (i have not tried it), uboot will not load the firmware, but Linux will load the firmware, but in this case, since firmwares are loaded little later, you would see the value of the pinmux from the firmware.

Could you please confirm if you are observing this behavior, ie on the first boot, pinxmux value is from Linux and after reboot command, pinmux value is from firmware?

Regards,

Brijesh

Hi Brijesh:

on the first boot, pinxmux value is from Linux and after reboot command, pinmux value is from firmware?

==> Yes, our observation just like this describe result.

And you can see the log file which I upload earlier1263.V3GA_pinmux_diff.txt

In this log, we follow below steps

Step 1 : Power on our customer board.

Step 2 : After boot finished, check 11c000.pinmux table first time.

Step 3 : Reboot our customer board in MAIN-UART.

Step 4 : After reboot finished, check 11c000.pinmux table second time

Step 5 : Reboot our customer board in MAIN-UART.

Step 6 : After reboot finished, check 11c000.pinmux table third time

And the step2 pinmux is more closely to linux config, step4 & step6 are firmware config.

but Linux will load the firmware, but in this case, since firmwares are loaded little later,
==> In your suppose, what firmware mode should mcu2_0 core be loaded in this moment?
Because in my log, you can see mcu2_0 core all attached as IPC-only mode in three boot times.
Is it match your suppose?

Hi Chen,

Not all cores are in IPC-Only mode. I see R5F loaded at 0x5d00000 is not in IPC-only mode, after reboot command.. It seems it is getting loaded by Linux..

Which SDK release are you using? What all cores are enabled in your build?

Hi Brijesh:

==> No matter psdkla or psdkra, we all use 07_00 version.

And we only build vision_apps related firmware files(j7-main-r5f0_0-fw / j7-c66_0-fw / j7-c66_1-fw / j7-c71_0-fw),

so you see the 0x5d00000 is not in IPC-only mode is normal.

Yes, it is normal, it just means Linux is loading the firmware. But before that, can you please check what all firmwares are present in the /lib/firmware folder?

Hi Brijesh:

==> Yes, we already make sure those firmware files (j7-main-r5f0_0-fw / j7-c66_0-fw / j7-c66_1-fw / j7-c71_0-fw) already flash into /lib/firmware/ folder on our eMMC.

which pins pinmux values are changing?
==> Yes, some pins we need to control (like GPIO0_75/GPIO0_76/....) are different between first power-on and after reboot.

GPIO0_75:
First Power-on : pin 76 (PIN76) 11c130 00050007 pinctrl-single
After Reboot   : pin 76 (PIN76) 11c130 00010004 pinctrl-single

GPIO0_76:
First Power-on : pin 77 (PIN77) 11c134 00050007 pinctrl-single
After Reboot   : pin 77 (PIN77) 11c134 00010004 pinctrl-single

Not only the two pins different, you can see below compare picture,

Now we already know how to config pins to correct pinmux in firmware part,

but the real problem of why different between first power-on and after reboot is still alive.

Hi Chen,

Many of these pins are muxes with the ethernet pins, so i think if you have enabled ethernet firmware in main2_0 firmware, then it might be overwriting it.

Can you try disabling ethernet firmware on main2_0 and see if pinmux remain same consistant?

Regards,

Brijesh

0 Sentinen.Chen over 5 years ago in reply to Brijesh Jadav

Expert 2415 points

Hi Brijesh:

Sorry, I didn't understand why to try disable ethernet firmware.

Because if this main2_0 firmware already enable ethernet function,

then no matter first power-on or reboot, we all need to see the ethernet firmware overwriting pinmux, right?

Or there is same thing else you want to see in disable ethernet firmware situation?

Hi Chen,

I tested it on the EVM. I don't see any pinmux difference between runs.. After reset and reboot command the 100 registers from 0x11c000 exactly are same. I have attached pinmux values for both the cases...
