I am having trouble getting MSGQ_get() to work when set to non-blocking,
i.e. with the parameter "WAIT_NONE". 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.
Index: message.c

if (DSP_FAILED (status)) {
MESSAGE_1Print ("MSGQ_get () failed. Status = [0x%x]\n",
status) ;
If anyone has some pointers to what I am doing wrong or where to look,
please let me know.
