Kelby, We found this issue recently, and it needs a fix in sync.c file. I will send it separately to you.

It works fine blocking. I am using dsplink 1.60, and testing on the DM6446 EVM. The symptom of the problem is the Linux OS freezes, requiring a reboot. I have isolated the problem with the following changes to the GPP 'message' sample application which is provided with dsplink.
