Hello everyone,
I am working to use RAUC in our system as updating framework. I am using
meta-rauc layer in yocto and everything works correctly.
The point is, now I want to do some changes in Rauc and I cannot find any source
of it in my build directory! It is only the compiled files.
It is strange, although in all RAUC-recipes, SRC_URI is set to the github, it
means I should see the downloaded source in my build directory.
does anyone have an idea? How can I apply my patch to the RAUC?
by default you should find the source in the work directory which is something
like
tmp/work//rauc/1.1-r0/rauc-1.1/
However, the sources won't be present if you build with having rm_work[1]
enabled.
The simplest way to modify rauc out of Yocto is to use the 'devtool' [2]
devtool modify rauc
which will create a 'workspace' layer and unpack the sources, etc. there.
You can also automatically create patches from this or deploy the updated tool
to the target via ssh.
Best regards
Enrico
