Build Kernel on ROCK 5B

Below is the instructions of how to build kernel for ROCK 5 on rock5 board.

Available boards:

ROCK 5A
ROCK 5B

Install essential pacakges

$ sudo apt-get update
$ sudo apt-get install -y git  device-tree-compiler libncurses5 libncurses5-dev build-essential libssl-dev mtools bc python dosfstools bison flex rsync u-boot-tools make

Get the source code

Clone the source code

$ mkdir ~/rk3588-sdk && cd ~/rk3588-sdk
$ git clone -b linux-5.10-gen-rkr3.4 https://github.com/radxa/kernel.git
$ git clone -b master https://github.com/radxa/rkbin.git
$ git clone -b debian https://github.com/radxa/build.git

And you will get

build  kernel  rkbin

Directories usage introductions:

build:
- Some script files and configuration files for building u-boot, kernel and rootfs.
kernel:
- Kernel source code.
rkbin:
- Prebuilt Rockchip binaries, include first stage loader and ATF(Arm Trustzone Firmware).

Build kernel

By default, the kernel branch is linux-5.10-gen-rkr3.4.

Build kernel with default rockchip_linux_defconfig.

$ cd ~/rk3588-sdk
$ ./build/mk-kernel.sh rk3588-rock-5b    # For ROCK 5B

Change kernel config

Optionally, if you want to change the default kernel config

$ cd ~/rk3588-sdk
$ cd kernel
$ make rockchip_linux_defconfig
$ make menuconfig
$ make savedefconfig
$ cp defconfig arch/arm64/configs/rockchip_linux_defconfig

Build kernel with new defconfig

$ cd ~/rk3588-sdk
$ ./build/mk-kernel.sh rk3588-rock-5b    # For ROCK 5B

You will get the kernel image and dtb file

$ ls out/kernel/
Image  rk3588-rock-5b.dtb

Build kernel package

The kernel package build can pack the kernel, device tree, modules and firmware into Debian packages, which makes it easier to install on the ROCK 5.

$ ./build/pack-kernel.sh -d rockchip_linux_defconfig -r 99 # [-d rockchip_linux_defconfig: kernel defconfig] [99: release number]

The generated packages will be copied to out/packages directory.

$ ls out/packages/
linux-5.10.110-99-rockchip-g9fd61a9a9912_5.10.110-99-rockchip_arm64.changes
linux-headers-5.10.110-99-rockchip-g9fd61a9a9912_5.10.110-99-rockchip_arm64.deb
linux-image-5.10.110-99-rockchip-g9fd61a9a9912-dbg_5.10.110-99-rockchip_arm64.deb
linux-image-5.10.110-99-rockchip-g9fd61a9a9912_5.10.110-99-rockchip_arm64.deb
linux-libc-dev_5.10.110-99-rockchip_arm64.deb

Install kernel packages

When you want to install specified kernel packages to your OS, try the following steps.

$ sudo dpkg -i out/packages/linux-headers-5.10.110-99-rockchip-g9fd61a9a9912_5.10.110-99-rockchip_arm64.deb
$ sudo dpkg -i out/packages/linux-image-5.10.110-99-rockchip-g9fd61a9a9912_5.10.110-99-rockchip_arm64.deb

And you will find that some files are generated in the /boot directory.

Check configuration file /boot/extlinux/extlinux.conf.

FAQs

1.When build kernel packages, there is one error "internal compiler error: Segmentation fault", like this:

  CC [M]  drivers/net/wireless/rockchip_wlan/rtl8852bu/phl/test/verify/phl_test_verify.o
during GIMPLE pass: local-fnsummary
drivers/net/wireless/rockchip_wlan/rtl8852be/phl/test/mp/phl_test_mp_reg.c: In function 'phl_mp_reg_read_macreg':
drivers/net/wireless/rockchip_wlan/rtl8852be/phl/test/mp/phl_test_mp_reg.c:320:1: internal compiler error: Segmentation fault
  320 | }
      | ^
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-10/README.Bugs> for instructions.
The bug is not reproducible, so it is likely a hardware or OS problem.
make[9]: *** [scripts/Makefile.build:274: drivers/net/wireless/rockchip_wlan/rtl8852be/phl/test/mp/phl_test_mp_reg.o] Error 1
make[9]: *** Waiting for unfinished jobs....
  CC [M]  drivers/net/wireless/rockchip_wlan/rtl8852bu/phl/test/verify/dbcc/phl_test_dbcc.o

We can just ignore it. Please add the following patch in repository build. And build kernel again via command ./build/pack-kernel.sh -d rockchip_linux_defconfig -r 99
