# linux-elphel
Extras (drivers, etc.) and patches for the kernel

##Downloading
Code must be located in `poky/` directory. Navigate to `poky/` and run:
```
git clone https://github.com/Elphel/linux-elphel.git
```
##Generating links and headers
Links between project tree and kernel source tree are generated by Bitbake during 'unpack' task. Some required header files are automatically generated during the build process.
```
. ./oe-init-build-env
bitbake linux-xlnx -c clean -f
bitbake linux-xlnx -c unpack -f
bitbake linux-xlnx -f
```
