how to compile custom kernel

[wahaha 4]

Hi,

i am referring to the instructions here: https://gist.github.com/TinkerTeam/6286550ce70d34f6b3d483cd803da786#gistcomment-3563189 on how to compile my own kernel for tinker board 2s. 

However, in the guide above, it listed that that it is targeting: 

# Fetch Tinkerboard kernel config
curl -L https://raw.githubusercontent.com/TinkerBoard/debian_kernel/develop/arch/arm/configs/miniarm-rk3288_defconfig -o arch/arm/configs/miniarm-rk3288_defconfig

  But with tinker board 2s, it is a RK3399 64 bit chip. Where should I be looking at to obtain the correct defconfig?

Thanks,

Jake

hello @wahaha, 

you can use the following to build kernel:

make clean && make distclean && make mrproper
make ARCH=arm64 tinker2_defconfig
make ARCH=arm64 rk3399-tinker_board_2.img -j24

Hi @tooz,

can i please clarify with you. I am trying to rebuild the stable kernel release from https://www.kernel.org/ which is currently (5.15.5).

The steps that I take are as follows:

1. download linux-5.15.5.tar
2. untar (1)
3. cd linux-5.15.5
4. cp arch/arm64/configs/config .config
5. make menuconfig (optional if there are stuffs in .config that you want to amend) -> save it in .config file
6. make -j24 bindeb-pkg
----- currently it is still going through no6 -----

but after that is done, i should have an iso file that i can then do a sudo dpkg -i linux-image.deb followed by a reboot.

Is this correct?

I tried the 3 steps you listed, but i'm not sure at which stage should that be done instead?

hello @wahaha, 

linux-5.15.5 is missing dts, we'd suggest to use the kernel from Tinker Board 2S github: TinkerBoard/debian_kernel: Debian Kernel source for Tinker Board (github.com)
