[Flashforth-devel] flashforth on Mega 2560

[Christopher H. <chr...@li...>]

Hi, I've been able to install flashflorth on 328P, running on an Uno
board, using avrdude to upload the 328-16MHz-38400.hex file. I was
wanting to put flashforth also on a 2560 running on a Mega 2560 arduino
board. I adapted the avrdude command I used for the 328P, to this
command for the 2560:

avrdude -c stk500v1 -p m2560 -P /dev/ttyUSB0 -b 19200 -e -u -U
flash:w:2560-16MHz-38400.hex:i -U efuse:w:0xff:m -U hfuse:w:0xda:m -U
lfuse:w:0xff:m

avrdude seems to upload the code, and set all the fuses, without any
trouble. However, when I connect to UART with ff-shell or with picocom,
there seems to be no response from the chip. I can see on RX LED that
the characters I'm sending are making it to the board, but nothing
comes back on the TX LED.

Is there something I need to be doing different for the 2560? Different
fuse bit settings...? Has anybody run FF lately on 2560?
