How do I build 5.10 kernel for ITX-3568JQ?

geekay

I can see only linux 4.19 in the SDK, but I need at least linux 5.4. The documentation states that there  is linux 5.10 working with the itx-3568. Where can I get the sources?

The sdk I have is rk356x_linux_release_v1.3.0b_20221213, last commit

I was able to build kernel image 5.13 with buildroot from the SDK. How can I build kernel.img and flash it to emmc?

The linux kernel in firefly's sdk is 4.19, and  the image is built quite ok, but I need at least 5.4. So I tried to build it according to buildroot's instructions (arch/arm64/configs/rockchip_linux_defconfig), and got Image.gz and rootfs (cpio, ext2 ant tar). I reckon, all I have to do, is to partition the emmc the right way. What should be done to make the firmware image out of this?
Kernel 5.10 from https://github.com/linux-rockchip also is built, but w/o modules (ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make -j6 rockchip_linux_defconfig).
The whole deal is being done in linux mint, hence I don't think that the containerization (docker, podman, etc) should make any sense...

I have just built kernel.img and upgrade_tool refuses to flash it to emmc with

1. # ./upgrade_tool uf rk356x_linux_release/rk356x_linux_release_v1.3.0b_20221213/kernel/kernel.img
   
2. Using /home/geekay/devel/firefly3568/rk356x_linux_release/rk356x_linux_release_v1.3.0b_20221213/tools/linux/Linux_Upgrade_Tool/Linux_Upgrade_Tool/config.ini
   
3. Program Log will save in the /root/upgrade_tool/log/
   
4. Loading firmware...
   
5. Loading firmware failed!
   
6. Note:invalid tag of firmware,please check firmware

Copy the code

What else should be done to flash the new kernel.img?

Is anybody here? I'm still stuck at
1. Finding linux 5.10 SDK from firefly
2. Packing buildroot output to rockchips sophisticated *.img files.

Can I get  any help or should I throw away this crapboard and forget about firefly's products?

There is no linux 5.10 SDK from firefly for ITX-3568Q, only 4.19
