Initialization is often blocked by GateMP_create

Hi, all!

We are using DVRRDK_04.00.00.03 and TI8168.

The calling sequence is:
main_m3vpss.c > main > System_start > System_main > System_init > IpcOutM3Link_init > IpcOutM3Link_initListMP > System_ipcListMPCreate > GateMP_create

Blocking often happens in function GateMP_create, so that initialization cannot complete.

What factors may lead to blocking in function GateMP_create?

Thanks in advance!

    Do you get any excpetion print or is it just blocked. Can you connect to M3VPSS using CCS+JTAG and halt the processor and check where control is ?

    GateMP create allocates from a sharedMemoryHeap and initializes some data structures. It should not block unless some core has taken ownership of HWSpinlock0 and then crashed preventing any other core from taking ownership.

    Thank you for the replay!

    Although we don't now which core blocks the exection, Our problem is solved now.

    It is because we didn't invoke unload.sh during previous system rebooting.
