Requires a very recent toolchain, because ATmega32U2 is relatively new.
|
|
|
|
- Building:
|
|
|
|
make
|
|
|
|
- Uploading the firmware to a Ben (for flashing with the atusb-pgm cable):
|
|
|
|
make HOST=<hostname> upload
|
|
|
|
Example:
|
|
|
|
make HOST=ben upload
|
|
|
|
HOST defaults to "jlime".
|
|
|
|
- Flashing the boot loader:
|
|
|
|
Prerequisite: avrdude on the Ben.
|
|
|
|
Disconnect the atusb board from USB. Insert the atusb-pgm connector into
|
|
the Ben. Place the atusb-pgm adapter on the exposed contact pads of the
|
|
atusb board and push it down. Then run
|
|
|
|
make prog
|
|
|
|
This takes about 30 seconds. If the programming fails with an error
|
|
message like "Yikes! Invalid device signature.", verify that the
|
|
atusb-pgm board is properly connected and placed, then try again.
|
|
|
|
- Uploading the application:
|
|
|
|
Prerequisite: dfu-util installed on the PC.
|
|
|
|
Insert atusb into the PC, then run
|
|
|
|
make dfu
|
|
|
|
Note: since the boot loader resets the USB bus after timing out,
|
|
this operation can fail with a message like "No DFU capable USB device
|
|
found". Just retry, and it will eventually get through.
