Here's what I got
Flash the firmware from repository.
/home/arturj/kkmulticopter/lib/avrdude/linux/avrdude -C
/home/arturj/kkmulticopter/lib/avrdude/linux/avrdude.conf -p m168p -P usb -c
usbasp-clone -B 8 -e -U lfuse:w:0xe2:m -U hfuse:w:0xde:m
avrdude: Warning: cannot query product for device: No error
avrdude: error: could not find USB device with vid=0x16c0 pid=0x5dc
avrdude done. Thank you.
Error during setting the fuses.
Flashing of firmware aborted.
Looks like this happens inside usbOpenDevice function. If product name can not
be read, function returns an error and program considers this a fatal failure.
Perhaps instead we shoud just display a warning and not return an error or
calling code should not consider this a fatal error, just a warning and
continue. If we didn't have product id to begin with, chances are we don't care
what it is. So change
errorCode = USB_ERROR_IO;
fprintf(stderr,
"%s: Warning: cannot query product for device: %s\n",
progname, strerror(libusb_to_errno(r)));
to
errorCode = 0; /* we don't care, act like nothing
happened */
fprintf(stderr,
"%s: Warning: cannot query product for device: %s\n",
progname, strerror(libusb_to_errno(r)));
Or change
if (usbOpenDevice(&PDATA(pgm)->usbhandle, pgm->usbvid, pgm->usbvendor,
pgm->usbpid, pgm->usbproduct) != 0) {
to also consider usbOpenDevice returning USB_ERROR_IO a non-failure
result = usbOpenDevice(&PDATA(pgm)->usbhandle, pgm->usbvid, pgm->usbvendor,
pgm->usbpid, pgm->usbproduct
if (result !=0 && result != USB_ERROR_IO) {
Also, why are we making original USBasp, it's old version and NIBObee special
cases hardcoded into usbasp_open function? Shouldn't the code be made generic
and these 3 also moved to config file?
