Aria 10 Compiling Linux Build Kernel and Rootfs Using Angstrom-Yocto distribution Error

Hi,

On link below, compiling Linux and Build Kernel and Rootfs Using Angstrom-Yocto distribution steps are described.

We have been following these steps to build the kernel and rootfs correctly. However, at the “repo sync” stage, we have been facing with a problem. The below link is broken and cannot be accesible.

https://github.com/altera-opensource/meta-altera-refdes/

We need to reach this link since this is the default link introduced at the
~angstrom-build/.repo/local_manifests/altera.xml
We have also tried to change this, but we got some other errors again sourced from the failed github link(404 error for github).

Any help would be appreciated. Thanks.
