-+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.
-+
-+
-+HULUSB notes:
-+-------------
-+To prepare and flash the firmware on a HULUSB device some additional steps are
-+needed;
-+
-+avr-objcopy -O ihex -R .signature -R .fuse -R .eeprom hulusb.elf hulusb.hex
-+dfu-programmer at90usb1287 flash hulusb.hex

-Subject: [PATCH 4/8] atusb: Build updates
-
-Update the root level Makefile to both invoke "make atusb.dfu" when
-building.
-
-Update the INSTALL document to mention the dependency on dfu-util.
-
-Update the root level Makefile to install atusb.dfu if it's compiled.
-Even though the kernel itself doesn't load the firmware into the
-device this will ensure that pre-compiled firmware is included in the
-release tarballs.
