build respeaker v2 linux kernel

Modify the path to the cross-compile toolchain. Default is my own path

baozhu@bz:~/workspace/respeaker/rk-linux-develop$ cat .CC 
#CC=/usr/bin/arm-linux-gnueabihf-
CC=/home/baozhu/workspace/respeaker/rk-linux-develop/tools/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

./build/mk-kernel.sh

The compilation generates the Linux deb package, which can be updated directly on the board

baozhu@bz:~/workspace/respeaker/rk-linux-develop$ ls out/deploy/
linux-4.4.159-respeaker-r2_1stable_armhf.changes             linux-headers-4.4.159-respeaker-r2_1stable_armhf.deb  linux-libc-dev_1stable_armhf.deb
linux-firmware-image-4.4.159-respeaker-r2_1stable_armhf.deb  linux-image-4.4.159-respeaker-r2_1stable_armhf.deb

build respeaker v2 u-boot

./build/mk-uboot.sh respeaker

The compiled binaries are here

baozhu@bz:~/workspace/respeaker/rk-linux-develop$ ls out/u-boot/
idbloader.img  trust_with_ta.img  uboot.img

The deployment method can be seen here.

Note

The complete directory structure is shown below, and any missing toolchains should be downloaded from Google
