7- Uploading the firmware to a Ben (for flashing with the atusb-pgm cable):
8
9  make HOST=<hostname> upload
10
11  Example:
12
13  make HOST=ben upload
14
15  HOST defaults to "jlime".
16
17- Flashing the boot loader:
18
19  Prerequisite: avrdude on the Ben.
20
21  Disconnect the atusb board from USB. Insert the atusb-pgm connector into
22  the Ben. Place the atusb-pgm adapter on the exposed contact pads of the
23  atusb board and push it down. Then run
24
25  make prog
26
27  This takes about 15 seconds. If the programming fails with an error
28  message like "Yikes! Invalid device signature.", verify that the
29  atusb-pgm board is properly connected and placed, then try again.
30
31- Uploading the application:
32
33  Prerequisite: dfu-util installed on the PC.
34
35  Insert atusb into the PC, then run
36
37  make dfu
38
39  Note: since the boot loader resets the USB bus after timing out,
40  this operation can fail with a message like "No DFU capable USB device
41  found". Just retry, and it will eventually get through.
