dev environment, Contiki, open-mc13224v,


2021-09-17: I re-created this page on my self-hosted web server.

2012-07-25: I installed Instant Contiki 2.6 in VirtualBox, and proceeded to compile some examples: First, set correct keyboard layout:

setxkbmap no

then, go contiki

cd ~/contiki/examples/hello-world
make TARGET=redbee-econotag hello-world

which worked. I then connected the econotag to the host, enabled it in VirtualBox... but the upload target doesn't exist:

make TARGET=redbee-econotag hello-world.upload

Hmm, Define an alias (in ~/./bash_aliases):

alias mcload='/home/user/contiki/cpu/mc1322x/tools/'

add my user to the dialout group:

sudo adduser user dialout

try an upload:

mcload -f hello-world_redbee-econotag.bin -t /dev/ttyUSB1
(here I press the RESET button on the board)
