Parts of the build system came from U-boot and Darrel Harmon's
"darrell's loader" for the AT91RM9200. Other parts from the Contiki
OS.

The Contiki MC1322x port includes libmc1322x as a subtree. This makes
pulling updates to libmc1322x easy, but pushing changes from contiki
to libmc1322x is not so easy. However, this should not stop you from
implementing core features in contiki first, (especially if you are in
a bind). The way to do this is to make files prefixed with contiki-*
in cpu/mc1322x and add them to Makefile.mc1322x.
For instance, if you need a routine called sleep, but libmc1322x
doesn't have that yet, you could implement sleep in
contiki-crm.c. Feel free to use as many contiki specific things in
here as you want. We can pull these changes directly into the contiki
tree. There is nothing stopping you from making changes to the lib
files --- in fact you should if that is the right thing to do (and
then push your changes upstream). The subtree merge should make it
easy to still pull updates.
You'll also notice that the libmc1322x build system is still
present. This allows you to cd ./tests and make all of the libmc1322x
unit tests as normal. This is a handy way to perform a sainity check
on all of the mc1322x specific code.
The subtree was set up as follows:
From:
http://www.kernel.org/pub/software/scm/git/docs/howto/using-merge-subtree.html
Moved mc1322x.lds to mc1322x.lds.contiki
Setup with:
git remote add -f libmc1322x git://git.devl.org/git/malvira/libmc1322x.git
git read-tree --prefix=cpu/mc1322x -u libmc1322x/master
git commit -m "Merge libmc1322x as a subdirectory"
And to do subsequent merges from libmc1322x do:
git pull -s subtree libmc1322x master

- openocd flashing
use run_algorithm to hook ROM NVM functions
see flash/stm32x.c
- add timestamp to received packets
- add a way to set modes: tx_only, rx_only, txrx. (so you can be lazy
and have blocks of code that don't need to handle rx packets)
- beacon sync
- CCA and ED.
