Working on getting the readwrite sample to work on an L138. When trace is enabled, there seems to be an issue leaving DRV_Invoke during the attach process. No matter what file I use(readwrite.out normally but I've even tried non-DSP junk files), the error and status are always the same. A partial trace is below showing this issue.
What would cause the DRV_Invoke to fail during the attach process?
