STM32H757 / RTOS / OpenAMP / Memory "._user_heap_stack " Size Saturation

[StrangeTau]

Hello

I'm developing RTOS environment of dual-core in STM32H757.

I could refer to the examples provided by STM32, and I read the application note AN5617.

I checked that the error is a exception "err1" under the function "rproc_virtio_create_vdev" in the remoteproc_vrtio.c file. it was caused by the saturation of the memory "._user_heap_stack". Please refers to debugging results and the memory map.

How can I resolve this error?

Is it because I didn't add memory flush logic?

Task ICP(Inter Core Processing) in RTOS handles communication between CM7 and CM4.

the task that is applied HSEM synchronization repeatedly runs from the functions "MAILBOX_Init" and "MX_OPENAMP_Init" to the function "OPENAMP_DeInit".

# PICTURE1. The err1 under the function "rproc_virtio_create_vdev" in the remoteproc_virtio.c file

 

+) The function "virtqueue_allocate" codes

+) The function "metal_free_memory" codes

# PICTURE2. The debugging results

1)  Hexadecimal conversion

2) Test end point

3) Test start point
