This patch adds support for the rzusbstick for the atusb firmware. More detailed information about this usb stick: http://www.atmel.com/tools/rzusbstick.aspx Original I have the rzraven kit: http://www.atmel.com/tools/rzraven.aspx Which comes with a special cable and avr dragon programmer. You need some programmer and wires to the programmers pins. To lookup how to connect the programmer to the rzusbstick pinout, see: http://www.atmel.com/Images/doc8117.pdf page 22 (schematics of the rzusbstick). Difference between atusb and rzusbstick(rzusb) is mainly the at86rf231 vs at86rf230 one. The rzusb contains the at86rf230 which is a little bit hard to deal with it (and has a huge errata inside the datasheet). Nevertheless with small schanges the atusb firmware can run now on the rzusb. The rzusb contains also a bigger mcu, so we can maybe cache more pdus for receive handling. To compile the rzusb firmware call: make NAME=rzusb this will generate the rzusb.bin then call the programmer (in my case avrdude): avrdude -P usb -c dragon_jtag -p usb1287 -U flash:w:rzusb.bin NOTE: currently there is no chance (I suppose) to ensure that the atusb receive the correct firmware, so don't try to flash the atusb with the rzusb firmware! Also the vendor and product id is the same. This currently a RFC, it's a quick hack and I think we should update more the documentation to support the rzusb.
