TDA4VMXEVM: R5F;MCU2_0;multitask;

HI,

I wrote a multitasking program that runs on MCU2_0.

If I create only one task, the firmware can start normally.

If I create two or more tasks, mcu2_0 cannot start normally, but I don't know where the problem lies.

Here is my code. Terminal does not print any log about mcu2_0 after running.
