Need Support in Multicore Debugging CCS- TDA2PX

Hi Gokul,

Can you please provide more details about the use-case? How this MCAN is being used in the system?

When you disconnect the PCAN, MCAN will start throwing errors as there is no other node available on the bus. Are you handling MCAN errors in your use-case? Do you have bus-off recovery sequence handled in the code?

Also, when you connect to TDA2P through CCS after freeze, can you look at MCAN register to see in what state MCAN is? You can look at MCAN_ECR, MCAN_PSR and MCAN_IR registers.

Thanks & Regards,
Vivek Dhande.

Hi Vivek,

I will update the complete use-case in email. 

I don't see error in the console.

Hello Vivek,

We are not able to find the root cause. Still we are on debugging.

Hi Vivek,

We are facing some crash issue during one of our test-case scenario. ( CAN disconnect).

 During CAN disconnect , system is freezed.

 We are expecting normal behavior of the system, even when there is no CAN data. (Camera & display should not be freezed)

 I see below error when I connect the CAN again

 [IPU1-0]   3306.653053 s: UTILS: MBX: Utils_mbxSendCmd(): Msg Alloc Failed (0)!!!

[IPU1-0]   3306.662447 s: UTILS: MBX: Utils_mbxSendCmd(): Msg Alloc Failed (0)!!!

 I need system support in solving this issue. 

Regards,

Gokul
