Conflict between eRPC and usb msd due to USE_SHMEM

Question

I have an i.MX RT1160 Evaluation Kit.

1. On CM7, I have:

• Azure RTOS (ThreadX, FileX, UsbX)

• eRPC

2. on Cm4: Bare Metal and eRPC.

It seems that I need the preprocessor USE_SHMEM for eRPC.

When I add the preprocessor USE_SHMEM, eRPC is working but UsbX is not working as I want. Basicall, my usd mass storage device (msd) does not appear anymore in my Windows Explorateur.

If I remove the preprocessor USE_SHMEM, UsbX is working as expected but this time eRPC is not working any more.

Maybe the problem is how the memory allocation are defined. Please find attached the memory allocation.

Could you help me to solve this issue? I would like to have both eRPC and usb msd working at the same time.
