GMI Wait


I try to transfer data from an FPGA to a T30 with L4T (Toradex T30). The GMI controller is configured for synchronous Mux-AD 16-bit transfer.
The communication works in most parts.
But as my FPGA can not respond to a request with a fix delay, I would like to keep the processor waiting until it is ready.
I assumed that the GMI_WAIT signal (input to the CPU) allows me to signalize that I’m ready. But how do I have to configure the SNOR_CONFIG/SNOR_TIMING registers to have a variable time instead of waiting a fix time?

Thank you
Kind regards
