[C.CC USERS] FIRMWARE UPLOAD FAILTURE

[cljacobsen at gmail.com]

Hi,

Due to some problems with the bootloader on the Arduino Megas
(Atmega2560) the only way to upload an occam program is to upload both
the virtual machine and the bytecode in one go. The IDE cannot do this
at the moment, but it is possible to do it by hand. It requires quite
a bit of manual work which you may or may not have fun doing :)

1)
compile the program in the IDE


2)
use the run/upload button to attempt to upload the code
this step generates the ihex file, and it does not matter if
upload actually failes. The important things is to get the ihex file


3)
Use the script ihemerge.py script to generate a new ihex file that
combines the firmware for the mega1280 (which is compatible with the
2560) and the ihex file generated by step2

python ihexmerge.py
arduino/tvm/firmware/tvm-avr-atmega1280-16000000-arduinomega.hex
yourfile.ihex > combined.ihex


4)
use avrdude to upload the file, something like this:
bin/avrdude.exe -C bin/avrdude.conf -V -F -p atmega2560 -P COM4 -b
115200 -c stk500v2 -D -U flash:w:combined.ihex


That is unfortunately as easy as it gets at the moment.
