Tool/software:

Hi Team,

My customer is trying ethernet on the EVM with the following configuration:

A53: Linux
R5F0-0: RTOS (A53 remoteproc intializes core)

Could you give steps on how they can implement this? They tried combining some of the sample code provided, but could not get it working.

I have asked them to refer to the thread below, but because they are on Linux sdk v.10, they could not get the steps working.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1290012/am6442-running-enet_icssg_layer2-example-on-r5f-in-combination-with-linux

Could you give step-by-step to help customer get it running?

The steps they have tried on their own are as follows: (General idea is adding Enet(ICSS) function to ipc example)

Import ipc_rpmsg_echo_linux example
Add Enet(ICSS) EEPROM and I2C
1. In Sysconfig, add peripherals and match them to enet_lwip_icssg sample
Build and debug
1. They copied the outputted file to SD card's /lib/firmware and booted SD card

They've also added the devicetree file. https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/4857.k3_2D00_am642_2D00_evm.dts

Hello Tsunoda-san,

It will be a couple of days before I have the time to try this out on the latest SDK on my side. I am sending your thread to another team member in the meantime to see if they can offer assistance.

Regards,

Nick

Hello Tsunoda-san,

The E2E you have referred to above is the correct place to start. I will list down the steps in more detail below for the customer to use it with SDK v10:

MCU+ SDK example modifications:

1. All the modifications needed in the example are listed on this page: https://dev.ti.com/tirex/explore/node?node=A__AScRgxl3hmonfFqU7DrFFw__AM64-ACADEMY__WI1KRXP__LATEST

Note: Since the auto-generated linker file is not used by enet_lwip_icssg example, the changes made in Update linker file page will have to be applied manually.

2. Rebuild the example to get the .out file, copy this file to the /lib/firmware/ti-ipc of the root partition.

Processor SDK modifications:

1. Device tree changes - Set 'status = "disabled";' for all ICSSG related nodes in the device tree.

It would be easiest to replace all the content of the icssg nodes with status = "disabled". Consequently, the respective pinmux settings of all nodes will have to be removed as well. See my reply here.

2. Resource configuration changes - Update the <ti-u-boot-folder>/board/ti/rm-cfg.yaml file to assign the PKTDMA channels for PRU Ethernet to R5F instead of the Linux A53 cores

Update the rm-cfg file using the resource partitioning tool, follow the detailed steps present here. Copy the generated file and replace the existing one with this.

Note: The steps in the link above are for R5F0_1 core, make sure to add the resources to MAIN_0_R5_1 (means R5F subsystem 0 core 0).

3. Compile and build the modified k3-am642-evm.dts file to generate corresponding .dtb file with "make linux-dtbs". Replace it in /boot folder of the SD card root partition.

4. Build u-boot and sysfw to generate the tiboot3.bin file with "make u-boot sysfw-image". Replace the tiboot3 in the SD card boot partition with our generated file.

Booting remote core from linux:

Follow the steps from here to boot remote core R5F0-0 from Linux.

Do let me know if you face any issues.

Regards,

Nitika

Hi Nitika,

They have followed your steps but are still having issues. Let me go step-by-step of everything they have done based on what you have mentioned. (Written in blue)

MCU+ SDK example modifications:

1. All the modifications needed in the example are listed on this page: https://dev.ti.com/tirex/explore/node?node=A__AScRgxl3hmonfFqU7DrFFw__AM64-ACADEMY__WI1KRXP__LATEST

Note: Since the auto-generated linker file is not used by enet_lwip_icssg example, the changes made in Update linker file page will have to be applied manually.

Generate the resource table as listed below in documentation
Add linux IPC to remote core project by adding IPC and enabling "Linux A53 IPC RP Message"
Disable other cores because they will not be using them to communicate via RPMSG.
Disable "A53SS0 Core 0" as well because they are using Linux for this core.
After configuration, the screen changed:

To enable remote core debug, the checked "Enable Memory Log" in "Debug Log".
They also enabled "Info Log".
Changes made like below.

Update the linker.cmd file as instructed in documentation like below:
Note: Since the auto-generated linker file is not used by enet_lwip_icssg example, the changes made in Update linker file page will have to be applied manually.
However, since MEMORY CONFIGURATOR is not used and the linker.cmd file needs to be edited manually, they used the one we provided before:

Allocated peripherals
- Since they do not intent to use other peripherals for IPC, no need to configure.
Allocate memory
- allocated in linker.cmd so not necessary to configure.

2. Rebuild the example to get the .out file, copy this file to the /lib/firmware/ti-ipc of the root partition.

After building the project in CCS, the put the .out file in the indicated location.

Processor SDK modifications:

1. Device tree changes - Set 'status = "disabled";' for all ICSSG related nodes in the device tree.

Changed the .dts file a little (check below)

2. Resource configuration changes - Update the <ti-u-boot-folder>/board/ti/rm-cfg.yaml file to assign the PKTDMA channels for PRU Ethernet to R5F instead of the Linux A53 cores

Update the rm-cfg file using the resource partitioning tool, follow the detailed steps present here. Copy the generated file and replace the existing one with this.

Note: The steps in the link above are for R5F0_1 core, make sure to add the resources to MAIN_0_R5_1 (means R5F subsystem 0 core 0).

Generated the rm-cfg.yaml file from SysConfig (Software Product: Keystone3 Resource Partitioning Tool 0.5, Device: AM64x)
Selected Browse and opened the file in C:\ti\mcu_plus_sdk_am64x_10_00_00_20\tools\sysfw\boardcfg\respart\am64x\k3-respart-tool-0.5\out
Disable A53 ICSSG1
- Packet DMA:
  - Change ICSSG1 Tx/Rx Channels Count to 0 and ignore the warnings.
- Packet DMA Ring accelerator:
  - Change the ICSSG1 Tx/Rx channel count to 0. "ICSSG1 Rx flows Count" also becomes 0 automatically.
Enable ICSSG1 on R0 side
- Packet DMA:
  - Change ICSSG1 TX channels count to 8, Rx channels count to 4 (This was by default configured to A53)
- Packet DMA Ring Accelerator:
  - Change ICSSG1 TX channels count to 8, Rx channels count to 64 (This was by default configured to A53)
All the resource sharing errors are resolved
Since they need to change the shared configurations for ICSSG1, they changed the "Share from Host" to "MAIN_0_R5_1" and "To The Host" to "None". Changed these all for the modules that show errors and the errors are resolved.
Save the generated rm-cfg.yaml file.
However, since the generated rm-cfg.yaml file does not fulfill the format required (causes error during build), they made the changes below.

Place the rm-cfg.yaml file in <ti-u-boot-folder>/board/ti/am64x

3. Compile and build the modified k3-am642-evm.dts file to generate corresponding .dtb file with "make linux-dtbs". Replace it in /boot folder of the SD card root partition.

placed the dts file in board-support/ti-linux-kernel-6.6.32+git-ti/arch/arm64/boot/dts/ti/
Build the device tree with > make linux-dtbs

Copy the .dtb file generated to the SD card

$ cd $SDK_INSTALL_DIR
$ make linux-dtbs
$ sudo cp board-support/ti-linux-kernel-6.6.32+git-ti/arch/arm64/boot/dts/ti/k3-am642-evm.dtb /media/<username>/rootfs/boot/

4. Build u-boot and sysfw to generate the tiboot3.bin file with "make u-boot sysfw-image". Replace the tiboot3 in the SD card boot partition with our generated file.

"make u-boot sysfw-image" fails so use "make u-boot" and copy the generated file to SD card

$ cd $SDK_INSTALL_DIR
$ make u-boot
$ make u-boot_stage
$ sudo DESTDIR=/media/<username>/boot make u-boot_install

Booting remote core from linux:

Follow the steps from here to boot remote core R5F0-0 from Linux.

Place the symbol link in the filepath for remoteproc

$ cd /lib/firmware
$ ln -sf /lib/firmware/ti-ipc/enet_lwip_icssg_am64x-evm_r5fss0-0_freertos_ti-arm-clang.out am64-main-r5f0_0-fw

Reboot linux

Find remoteproc and check boot status. (R5F0_0 is remoteproc0)

$ head /sys/class/remoteproc/remoteproc*/name
==> /sys/class/remoteproc/remoteproc0/name <==
78000000.r5f

==> /sys/class/remoteproc/remoteproc1/name <==

Hi Mari,

One issue that I can see is with the dts file, icssg1_iep0 should be disabled instead of the associated pins.

&icssg1_iep0 {
	pinctrl-names = "default";
	pinctrl-0 = <&icssg1_iep0_pins_default>;
};

&icssg1_iep0_pins_default {
	status = "disabled";
};

Thank you for the detailed steps above, I will look more into it and get back to you in some time.

Regards,

Nitika

Hi Mari,

Did the above suggested change in the dts file help? Is the example failing at the same location even with that change?

As mentioned in webex chat on thursday, the change in the dts file did not resolve this issue.

Hi Nitikal

Thank you for the update!

Just checking - is this for version 9.2 or 10.1?

Best regards,

Mari Tsunoda

0 Nitika Verma 6 months ago in reply to Nitika Verma

TI__Expert 7385 points

After modifying the above files, the same steps as mentioned in my first reply can be followed:

1. Rebuild the example to get the .out file, copy this file to the /lib/firmware/ti-ipc of the root partition.

2. Modify the rm-cfg file and re-build the U-boot binaries - using 'make u-boot'

3. Modify the k3-am642-evm.dts and k3-am64-main.dtsi file in processor SDK and rebuild the kernel - using 'make linux'

4. Replace the generated k3-am642-evm.dtb file and the u-boot files in the SD card (see U-boot files)

4. Follow the steps from here to boot remote core R5F0-0 from Linux.

Hi Nitika,

Thanks, will tell them to use v.9.2 on their end and match ICSDK.

And thank you for testing this on short notice!

Best regards,

For future readers, the big difference in the update Nitika made was resolving the resource conflict where both Linux and the R5F project were requesting the same I2C instance (Nitika, correct me if I got that wrong).

You can find more information about ensuring that your projects do not have resource conflicts in the AM64x academy's Multicore module:

Hi Nitika, Nick,

Do you know if the same files should be able to boot on SDK 10.1 as well?

Best regards,

Mari Tsunoda

0 Nitika Verma 6 months ago in reply to Mari Tsunoda

TI__Expert 7385 points

Hi Mari,

The same files might not directly work for 10.1 since the SDKs have undergone significant changes from 9.2 to 10.1. But, I expect following the same steps and changes in SDK 10.1 should work.

I think a team member is working on testing this with SDK 10.1, let me confirm with them and get back to you.

Hi Mari, I successfully was able to "enet_lwip_icssg_am64x-evm_r5fss0-0_freertos_ti-arm-clang.out" with IPC remoteproc using latest AM64x MCU+SDK10.1 and latest AM64x Linux SDK 10.1

I followed steps explained above by Nitika, Nick and followed Academy links. I will later summarize steps in an FAQ for future readers, but for now let me share files used and high-level changes

File changed in Linux SDK:

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/mod_5F00_k3_2D00_am64_2D00_main.dtsi

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/mod_5F00_k3_2D00_am642_2D00_evm.dts

MCU+SDK Changes:

SysConfig

- Remove UART uncheck in debug log, so no UART used in RTOS. Or, you can also change to another USARTx different to USART0 as this one is used in linux

- Enable IPC to get a resource table

- Take out I2C1 peripheral to avoid conflict with Linux

Linker.cmd

- Add DDR section for resource table

Hi Paula,

I just got a follow-up from my customer. The new example files are failing at the same step as mentioned in a previous reply. Do you know what could be the cause for this?

After debugging and adding log outputs, they realized that SOC_moduleSetClockFrequencyWithParent does not return SystemP_SUCCESS

I have asked them to send the R5F side files as well with the changes you mentioned in your reply 2 weeks ago.

Hi Mari, just to confirm do they use the same files posted? or created their own ones?. Checking if there is any possible difference.

One file I didn't share was sysconfig. Attached just in case

Hi Paula,

They created their own and tried to follow the steps listed in the FAQ as well.

They sent me their changed files. Would you be able to take a look at them for any differences?

(I will send these via email)

I will check if they have tried to directly replace the files.

Hello Mari,

Have we triple-checked that the customer is actually using the updated Linux devicetree file, applying the updated u-boot changes, and is loading the updated R5F binaries? That is the most common kind of issue I see in cases like this, where the customer rebuilds the files, copies them to the SD card, but does not finish updating the links, replacing files, etc.

Regards,

Nick

Hi Mari, I just tested shared MCU+SDK *.out from customer in my setup and it is working. FW is loading OK as shown below:

root@am64xx-evm:~# dmesg | grep remoteproc
[ 9.919805] k3-m4-rproc 5000000.m4fss: configured M4 for remoteproc mode
[ 9.972764] remoteproc remoteproc0: 5000000.m4fss is available
[ 10.027220] platform 78000000.r5f: configured R5F for remoteproc mode
[ 10.060743] remoteproc remoteproc1: 78000000.r5f is available
[ 10.309686] remoteproc remoteproc1: powering up 78000000.r5f
[ 10.318555] remoteproc remoteproc1: Booting fw image am64-main-r5f0_0-fw, size 3110148
[ 10.403811] remoteproc remoteproc1: remote processor 78000000.r5f is now up

root@am64xx-evm:~# cat /sys/class/remoteproc/remoteproc1/state
running

So, the issue is probably in their Linux side or in FW's symbolic link.

Can they send me their DTS, DTSI, or rm-cfg.yaml instead of just diff files? Or, alternatively, can they compare shared files in FAQ (or here) with theirs?

Also, echoing Nick, if they can double check they replaced correctly the files before building Linux, update correctly the SD card, and new "am64-main-r5f0_0-fw" symbolic link is correct, it would be great

thank you,

Paula

I got these files as well. I have sent them to you via email.

This is their log after they boot the R5F core through remoteproc. It seems like the core starts, but cannot get out of system_init().

They have checked their symbolic links and made sure that the files have been replaced with the newest date reflected.

Hi Mari, in order to get the demo to work correctly with Linux SDK and MCU+SDK 10.1 I have to further modify DTS from /board-support/ti-linux_xxxx/arch/arm64/boot/dts/k3-am642-evm.dts as well as /board-support/ti-u-boot-xxxxx/arch/arm/dts/k3-am642-evm.dts

In both files I completely deleted ICSSG1 to avoid conflicts with R5F using it.

After updating both DTS files, run "make linux" "make u-boot" and cp u-boot files to SD Card (example below) the application passed system_init() hang and worked OK

~/ti-processor-sdk-linux-am64xx-evm-xxxx/board-support/u-boot-build$ cp a53/tispl.bin /media/alice/boot/
~/ti-processor-sdk-linux-am64xx-evm-xxxx/board-support/u-boot-build$ cp a53/u-boot.img /media/alice/boot/
~/ti-processor-sdk-linux-am64xx-evm-xxxx/board-support/u-boot-build$ cp r5/tiboot3.bin /media/alice/boot/
~/ti-processor-sdk-linux-am64xx-evm-xxxx//board-support/ti-linux-kernel-xxxx/arch/arm64/boot/dts/ti$ sudo cp k3-am642-evm.dtb /media/alice/root/boot/dtb/ti/ (If you face "read-only filesystem" you might would need to do a mount point for this "root" partition)
