I am using VIP Suite (Video and Image Processing Suite). Access timings from processors other than Nios II may be strange. What can you think?

IP Nios II Platform Designer

It is highly likely that the configuration is processor dependent.

Since each IP of VIP Suite sends data in packet units, it is designed to wait for write/read. To avoid this, add a wait_request signal and check.

This wait_request signal is a signal that allows the slave port of the VIP to wait for I/O accesses from the slave side. Adding this signal extends the write or read, allowing for more reliable I/O access.
