RG350
build kernel
步驟如下：
$ cd $ wget https://github.com/tonyjih/RG350_linux/releases/download/2019.10.27/toolchain-2019-10-27.tar.bz2 $ tar xvf toolchain-2019-10-27.tar.bz2 $ sudo mv gcw0-toolchain /opt $ export PATH=$PATH:/opt/gcw0-toolchain/usr/bin $ git clone https://github.com/tonyjih/RG350_linux $ cd RG350_kernel $ ARCH=mips make rg350_defconfig $ ARCH=mips make vmlinuz.bin -j4
CONFIG_CMDLINE
"mem=0x0100M mem=0x0100M@0x30000000 console=ttyS2,57600 console=tty0 boot=/dev/mmcblk0p1 loop0=/boot/rootfs.squashfs root=/dev/loop0 rootfstype=vfat rootwait ro init=/sbin/init"
P.S. Kernel使用loop0掛載rootfs並且執行/sbin/init
