i set up my slavefifo app (BULK_IN )as CY_U3P_DMA_TYPE_AUTO_SIGNAL (for debugging).

I can produce an error condition on my GPIF and after that the CyFxSlFifoPtoUDmaCallback() is

not called anymore.

The only way to recover from this, is CyU3PDeviceReset().

But I do not want CyU3PDeviceReset(), because it forces a reload on the PC.

What can cause CyFxSlFifoPtoUDmaCallback() to stop working?

How can I see the relating error messages?

Best regards

What is the error condition you're introducing on the bus?

Is this error condition that you're talking about causing the GPIF to go into a infinite loop?
