Build Options

im240a : AT86RF230B w/ mega328.
im240a_eval : AT86RF230B w/ mega328 eval board.

Note:

In order to use the eval board be shure to follow the install guide.

replace jumper e by cable e1 on X5
switch S1 to power supply USB.

To program the mega328pa connect JTAG-ICE 10 pin header to X4.

avrdude -P usb -c jtag2isp -p m328p -B10 -t

The original fuses are LF 0xe2 HF 0xd4 EF 0x06

The original bootloader seems to be a proprietary one and handles the ISMT *.wfi format. It is a one line string starting with "WIMOD_ID_3#" followed by probably the ASCII representation of the firmware ... to be investigated.

In order to do a backup of the board use the following commands:

    avrdude -P usb -c jtag2isp -p m328p -B 10 -U fl:r:im240a_flash_initial.hex:i
    avrdude -P usb -c jtag2isp -p m328p -B 10 -U ee:r:im240a_eeprom_initial.hex:i

Restoration of the backup can be done by the command:

  avrdude -P usb -c jtag2isp -p m328p -B 10 \
            -U fl:w:im240a_flash_initial.hex:i \
            -U ee:w:im240a_eeprom_initial.hex:i \
            -U lf:w:0xe2:m \
            -U hf:w:0xd4:m \
            -U ef:w:0x06:m
