Programming and Debugging Targets

Programming with avrdude

Note
avrdude uses libusb to access JTAG-ICE, Dragon, ISP etc. Section Using USB connected Programmers under Linux describes, what to do, that normal users can access these devices.
(1) avrdude -P usb -p m1281 -c jtag2 -U fl:w:install/bin/sniffer_stk541.hex
(2) avrdude -P usb:4711 -p m1281 -c jtag2 -U fl:w:install/bin/sniffer_stk541.hex
(3) avrdude -P usb:1234 -p m1281 -c avrisp2 -U fl:w:install/bin/sniffer_stk541.hex

Debugging with avarice + avr-gdb (ddd)

avarice -I -P atmega1281 -2 -j usb --detach :4242
ddd --debugger avr-gdb install/bin/sniffer_stk541.elf &

When ddd/avr-gdb has opened, type "target remote:4242<ENTER>" in order to connect avarice and avr-gdb.

Using DebugWire

Enable DebugWire
  • use any isp capable programmer: stk500v2, jtag2isp, dragon_isp??
    ISPDUDE="-c jtag2isp -P usb -p t44"
    DWDUDE="-c jtag2dw -P usb -p t44"
    avrdude $ISPDUDE -F -U hfuse:w:????:m
    avrdude $DWDUDE -F
