Hello. I'm sending Message Type 11 packets from FPGA to C6678 DSP using SRIO. DSP is sending strange responses like this: Ftype = 0x0D, Ttype = 0x01, Status Field = 0x07 (Error), Transaction ID always = 50 (on DSP SYS-BIOS 6 is running, and SRIO type-11 socket is opened). When I send from FPGA NWRITE_R operation, it works fine, and Responses received from DSP are alright: transaction ID increments normally and matches transaction ID of request-message, Status = 0 (DONE), Ttype = 0x00, Ftype = 0x0D.
What is strange Transaction ID (50) in message-response packets and why this error occurs?
