    If you want to use another ptf on the kernel source tree, you need to clean up with "make .... clean" or "make ... mrproper". Then do hwselect again.

    Hi Alex.liu,

    How are you?

    The problem seem to be rootfs, it looks quite big.

    Please remove old rootfs, and copy it from buildroot again.

    rm -rf ~/rootfs

    cp -a ~/buildroot/build_nios2/root ~/rootfs

    cd ~/rootfs# remove include and lib to save space# the dev nodes are generated via ~/download/rootfs_list

    rm -rf dev usr/include usr/lib# you may use this instead of the one from buildroot

    cp ~/download/inittab etc
