Dear all, I modified a little the firmware of a usrp-based device. I wanted to check the buffer overrun event on the BULK IN EP2 FIFO, but the interrupt autovectoring mechanism doesn't work. The following code
SYNCDELAY; EP2FIFOIE = 0x01; /* The FF on the EP2, which is BULK IN */
SYNCDELAY; USBIE = bmSUDAV | bmURES | bmHSGRANT; }
I don't see any changes in the port D bit 0 or _usb_rx_overrun variable, even in case of the EP2 overrun, which I can less efficiently verify with EP2468STAT or EP24FIFOFLGS (and maybe EP2CS as well).
Any clue? Did someone ever try hook_fgv?
Regards, Mic
