MC1322x subtree
|
||
|
|
===============
|
||
|
|
|
||
|
|
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:

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
