Hello Everybody

I'm using the USB peripheral of the STR711 in polling mode. I have tried to only activate the SOF-interrupt, to have a milisecond timer. But when I enabled the USB low priority interrupt, the firmware got stuck in an endless loop, as soon as the first transfer occured on the USB. The USB low priority interrupt was called endlessly.

Even if I masked out all interrupt events of the USB peripheral in the CNTR register, the interrupt kept occurring, with the CTR flag set. I suppose, the CTRM bit in the CNTR register is not working. It seems to be impossible to mask out the CTR interrupt.

Can anybody approve this behaviour?

Regards
