Hi,
I've encountered problems reading data from the target with an olimex-v1
FET. Writing was ok.
Turned out (hopefully), that in cp210x.c/usbtr_recv() the function
usb_bulk_read() may legally return 0.
Modifying the code to:
do {
rlen = usb_bulk_read(tr->handle, V1_IN_EP, (char *)databuf,
max_len, TIMEOUT);
#ifdef DEBUG_CP210X
printc(__FILE__": %s : read %d\n", __FUNCTION__, rlen);
#endif
} while (rlen == 0);
solved my problem.
Should I submit a patch or is it ok in this way?
Hardy
PS: this at least holds true for windows/cygwin
