I don't know the answer to your problem. But I am curious how you read all the bytes from the RxB buffer. I am trying to transfer 40 bytes from labview to MCF52259, but I already have overrun error. Actually, I already have OE at 8 bytes. In the future, I need to pass hundreds even thousand of bytes. Could you show me how you manage to capture all your bytes? I am attaching my ISR as to how I am doing it now.
Thank you for your input.
