PROCESSOR-SDK-J721E: PROCESSOR-SDK-J721E:

Hi Mahmoud,

I have added steps in FAQ to integrate the patch, Please let me know here, if you face issues further.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1193315/faq-processor-sdk-j721e-enable-cdd-ipc-communication-with-a72

Currently updated Plugins are not released externally so you might not be able to configure IPC with A72, please use generated config files from patch until release.

Hello,

the original ticket is closed, the link https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1193315/faq-processor-sdk-j721e-enable-cdd-ipc-communication-with-a72 is not found.

Can you please share latest updates on due date for when we expect a fix for the IPC issue to communicate with A72 ?

Hello ,

Please find the attached patch for SDK 8.5 , this will enable MCU2_1 Main Domain R5F communication with A72 core.

Config plugin files are Updated with A72 and will be released as part of 8.6 release , currently the generated config files have been back ported to  8.5 SDK

and added in this patch.

This patch has been tested with bare metal Cdd Ipc Rproc Linux example application on MCU2_1 communicating with A72 core.

Steps to apply the patch and see the files changed in Linux machine :

• 1)  Download the patch into local directory.

• 2)  Go into ti-processor-sdk-rtos-j721e-evm-08_05_00_11/mcusw path

• 3)  git init

• 4)  git add .

• 5)  git commit -asm "Original SDK 8.5"

• 6)  git apply (path to patch in local directory)/(patch_name).patch

• 7)  git status 

Steps to compile example application:

make -s cdd_ipc_app_rc_linux CORE=mcu2_1 CDD_IPC_LINUX_BUILD=yes

(A Flag CDD_IPC_LINUX_BUILD has been added to build communication with A72, by default the value is no )

Hello Tarun Mukesh
I have 2 points needed to be confirmed to apply this patch:

1- We're using target J721S2 so is this patch applicable to our target 

2- The version of our SDK now is 8.4 so can we integrate these changes to this SDK (8.4) 

Regards

Hello,

The patch currently is applicable only for J721E , we can see the differences in the patch and adapt the same for J721S2.

I haven't validated the patch for J721E 8.4 but in 8.4 all PDK dependencies are already moved to mcusw .So i believe we can integrate the patch for the same.
