AM62A7-Q1: IPC usage

Xingyu Zhu
Expert 4335 points

Part Number: AM62A7-Q1

Tool/software:

Hi expert,

Our customer have successfully established communication between mcu-r5f and both DM and A53 based on rpmsp_char. They hope to separate vision_apps so that they do not interfere with each other.

Taking mcu1_0 (DM) as an example, can they share the same linux_resource_table, initialize the IPC for vision_app first, and then initialize their own IPC? They have already distinguished the vring_mem used by both.

They are concerned that sharing the same table might cause the later initialization to affect the earlier one.

When they tried to configure the linux_resource_table myself, the RTOS got stuck at WaitForLinuxReady after starting up

Best Regards,

Xingyu Zhu

    Can you please specify what is meant by implementing own IPC here?

    Also can you please tell, between what cores they want to share the linux_resource_table?

    Regards,
