TDA4VM-Q1: TDA4 SDK0805 IPC-ProcID can not use MPU1_0

hello, I just want to know that the IPC function between MPU1_0 and MCU1_0 if modified or not in sdk-0805?

Hello ,

Sorry for the delay.

Mcal CDD IPC communication between MCU1_0 and MPU1_0 is not enabled in SDK 8.5 , it is enabled for MCU2_1 in SDK 8.6 .

Pdk IPC can be used for the communication between MPU1_0 and MCU1_0 in SDK 8.5.

May I know why MCAL CDD IPC cannot support communication between MCU1_0 and MPU1_0? Currently we are using MCAL 7.3. Is there any guide to migrate MCAL7.3 with 8.5?

OK, get it, thanks.

Hello, I have an idea that I may use mcal8.5 with CddIpc in mcal8.6, can it work?

Hello, I do not have access to the patch file. May I get it from other URL?

Yes , we have currently enabled only MCU2_1 with MPU1_0 CDD IPC communication in SDK 8.6 but not with MCU1_0.

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, did you mean when I apply the patch, I can use IPC between MPU1_0 with MCU1_0 in SDK8.5?  If the file "MCUSW_02_00_00_06_CONFIG-windows-installer.exe“need update or not?

No you can't use MCU1-0 with MPU1_0 . You can use only MCU2_1 with MPU1_0.

As MCU1_ 0 has sci server running on it , it requires another task for CDD IPC. Whereas for MCU2_1 we can run CDD IPC directly.

In this patch i have added configuration generated files which enables CDD IPC communication between MCU2_1 and MPU1_0 .

But if you want to generate the files you have to move to SDK 8.6 and MCUSW_03_00_00_06_CONFIG-windows-installer.exe which also enables CDD IPC communication between MCU2_1 and MPU1_0

If I want to use IPC between MCU1_0 and MPU1_0, and use mcusdk8.6, should I use PDK8.6 on MPU1_0 and other cores? Now I just want to use SDK8.6 on mcu domain and SDK8.5 on main domain, can the IPC MCU1_0 and MPU1_0 work?

Yes, if you want IPC communication with MCU1_0 and MPU1_0 you have to use PDK IPC only.

I did not understand what you mean here.

Hello, I just want to ask that If I use PDK8.5, and mcusw version is 8.6, can it work, and Does the IPC between MCU1_0 and MPU1_0 work well?

Hello,

You shouldn't use PDK 8.5 and MCUSW 8.6 version, there are some inter dependencies which might trigger issues.

You can use PDK 8.6 IPC as well for communication between MCU1_0 and MPU1_0.

PDK IPC in both SDK8.5 and 8.6 have communication between MCU1_0 and MPU1_0 whereas MCUSW CDD IPC in SDK 8.5 and SDK 8.6 doesn't have  communication between MCU1_0 and MPU1_0.

MCUSW 8.6 has only MCU2_1 with MPU1_0 CDD IPC communication

Hello,

Now we run autosar software on MCU1_0, so we want to use the mcusw CddIc to set the IPC between MPU1_0 and MCU1_0. Do you mean that in SDK8.5 or SDK 8.6 we all cannot set it? and in the future, if the mcusw can set the IPC com between MPU1_0 and MCU_0 or not? if mcusw does not has the plan to set IPC between MPU1_0 and MCU1_0, would you give us some advice on how to set it?

Hello,

With current example of CDD IPC in SDK 8.6 we can set only MCU2_1 with MPU1_0.

But you can  adapt the same from MCU2_1 and create an example for MCU1_0 and MPU1_0 as you are using AUTOSAR OS on MCU1_0.

We have an internal ticket raised to add an example which communicates CDD IPC MCU1_0 with MPU1_0.Expected to be in future release.

thanks, I will try it.

Hello, after I applied the patch file, I found some changes, but the "MCUSW_02_00_00_06_CONFIG-windows-installer.exe" file wasn't updated. I cannot set the remote core to MPU1_0 with EB or Davinci, whereas found it in the file "Cdd_IpcCfg.c" in the folder ". /example", after I applied the patch.  May I modify this file manually? If there was other way to set it?

Hello,

As i told you already the patch contains only generated output files ,MCUSW_02_00_00_06_CONFIG-windows-installer.exe doesn't have MPU1_0 .You can modify the file manually but needs to be vigilant.

If want to generate the output files then MCUSW_03_00_00_06_CONFIG-windows-installer.exe (part of latest release SDK8.6) has MPU1_0 remote core.

Tarun Mukesh

thanks, I may modify and test it. By the way, if I need modify the software of MPU1_0 for this?

No need to modify for MPU1_0 it is there , you need to adapt for MCU1_0 instead of MUC2_1

Tarun Mukesh

thanks.
