TMS320C6678: NDK mixed with messageQ

Part Number: TMS320C6678

Hi,

mcsdk_2_01_02_06

ndk_2_21_02_43

ipc_1_24_03_32

The customer ping core0 from PC and Core0, Core1, Core 2 send messages to each other by MessageQ.

When using messageQ, ping will have a delay of tens of ms, if not,the delay within 1ms.

What may cause that? Any suggestions to optimize the procedure?
