Hi guys,
here after is a script I wrote to setup and bitbake stuff under
Ubuntu.
HOW TO USE:
DO NOT RUN THIS ON A MOUNTED NTFS PARTITION, you will get errors and it
will take weeks to figure out why (I learnt the hard way).
The script is configured to use dual core processors which speeds things up
a bit.
Just download and run the script, it will ask you where what folder you
want to make the main folder.
NOTE: The script will then open up .bashrc with gedit, this is to allow you
to remove additional OE_HOME entries if you add them accidentally, if there
is only one entry at the bottom of the file, just close gedit.
Once it has finished, if you go to
cd ${OE_HOME}/build
source profile
bitbake -k <some image>
TO DO:
I haven't implemented testing for some of the folders, but I don't have
time to revise it now, so feel free to add to the script and repost it.
I have some hard coded branches of OE and bitbake because I know these work
properly. Feel free to update and repost, just please make sure they work
properly.
OTHER STUFF:
I suggest you use the kernel provided by this website, as the OE one will
work but is lacking a lot of the mini2440 specific driver modules.
It took me days to setup OE the first time, the learning curve is just
terrible, so hopefully this will help.
Thanks to all of those guys who posted tutorials for OpenEmbedded.
Especially those who were working hard at this stuff 6 months ago when I
started out, and naturally to BusError.
Cheers
Paul
