Hi,
As I described in another thread, I can change the GPIF width at running time, but the setting does not take effect immediately. It becomes effective with the second packet after the change. I don't know why this happens.
Another issue is that I failed to change PIB clock at running time. I destroyed the DMA channels and called CyU3PPibDeInit and then call CyU3PPibInit to set new frequency and create DMA channels again. I found that the PIB clock is changed, but the GPIF has no output when there is out packet from USB endpoint.
Anyone has any idea on above issues?
Thanks,
Rover
