DSP6678

In testing the EDMA test cases of CSL in TI PDK 6678 library, I've encountered an issue. The 6678 EDMA gets stuck in the do while loop when running in a multicore environment.

Configuration as follows:
We are using pingpong mode for AB transfer, but when CCNT is set to a value greater than 1, the transfer fails. It gets stuck in the following function, polling on IPR bit 0.
Can you help with this? Thank you.
