DRA821U: MCU CAN Activating

Hello,

Are you asking for PSDK RTOS or PSDK Linux ?

Hi Tarun, 

It's about for both RTOS and Linux as well.

R5F runs at RTOS, A72 runs at Linux, Hence R5F MCU need to send the bufferrd CAN data to A72 side after boot up is done.

Hello Jack,

 I believe you are asking similar to this demo we have,https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j7200/09_00_01_01/exports/docs/mcusw/mcal_drv/docs/drv_docs/demo_boot_app_mcu_rtos_top.html

Can you please go through this and let me know whether this met you requirements ?

Hi Tarun

Thanks for your kind answer.

Yes, it's similar. Customer would like to implement MCU fast boot with MCAN fast activated while buffering the incoming CAN data before MAIN domain become active.

After MAIN doain boots up, MCU domain send the buffered CAN data to MAIN Domain. 

Can you please provide us with more detaied user guide to implement buffering incoming CAN data in MCU domain?

I'm unable to figure out the implementation details.

Thanks.

Hello Jack, 

You are expecting to get data on MCU DOMAIN CAN and send it to A72 running Linux.

Currently there is no such example doing this in our SDK

Hi Tarun

Yes, I understand that there is no sample code.
To implement Fastboot, please review the S/W structural level whether it is reasonable to send buffered CAN message to MAIN domain through IPC or other methods after fast activation of MCU CAN.

Thanks a lot.

Hello Jack,

Sorry for the delay. I was away due to emergency leave.

You can do this but need to ensure the rate of frame transfer from CAN via IPC to receiving CAN Frames .Even A72 running linux can access MCU Domain CAN.
