TDA4AL-Q1: How many paths(chn) can IPC support

Hi  Ti experts,

    HW: owner board

    SW:RTOS  08_05_00_11 SDK

mpu1 0(A7) communicates with mcu1 0(R5) through IPC. Whether two processes are started on A72 and run with R5 at the same time.

I find this case:

I'll run it separately  vx_app_arm_ipc.out or vx_app_multi_cam.out is normal.But running at the same time will generate an error about IPC.

so

1:IPC is or not support multipath

2:If multipath are supported, whether the number of multipath is limited

Thanks.
