build 4.14.108


編譯步驟如下:

$ cd
$ wget https://github.com/steward-fu/pocketbeagle/releases/download/v1.0/gcc-4.9.tar.gz
$ tar xvf gcc-4.9.tar.gz
$ sudo mv gcc-4.9 /opt
$ export PATH=$PATH:/opt/gcc-4.9/bin

$ wget https://github.com/steward-fu/pocketbeagle/releases/download/v1.0/kernel-4.14.108.tar.gz
$ tar zxvf kernel-4.14.108.tar.gz
$ cd kernel
