The official sent me the Armbian SDK, which includes kickpi-k2b-v2 and v1. I tested it and it can boot normally. Wired/wireless networks and Bluetooth all work fine, but the OTG function just won’t work no matter what I try. (g_ether and g_serial not woring) Anyway, I hope it can be merged into Armbian. I only compressed the config and patch folders, which should be sufficient. https://we.tl/t-wtmI81zB5e

I’ve sent the URL and details here, hoping they can take a look

I’ve spent way too much time on this, my back is killing me. I’d rather just buy a more common development board. My project didn’t require me to dig into all this u-boot and DTS stuff. So, fuck you KickPi. Here are all the DTS files I extracted from https://github.com/pyavitz/debian-image-builder and the official Linux SDK. Hopefully someone else can finish this job. dts.zip

Still no network. I checked the official SDK, it uses the following hardware: Wired network: Allwinner GMAC driver + external PHY; Wireless network: AIC8800 series WiFi module driver; Bluetooth: AIC8800 Bluetooth Low Energy driver; USB network: RTL8152 USB to Ethernet driver. Does this have any impact?

The parameters I’m using were extracted from the official Linux SDK using GPT. At least the DRAM parameters are functional. Debian can boot and log in normally, but there’s no wired network or WiFi/Bluetooth. I’m currently investigating why this is happening.

This one failed with "DRAM:This DRAM setup is currently not supported" I found something from kickpi's site:Linux_SDK_Compilation. including building u-boot https://github.com/tan-zhihao1/kickpi-book/blob/master/h618/en/04-SDK_Compilation_Guide/02-Linux_SDK_Compilation.md Its too huge so I deleted the folder "source" and "toolchains". hope it could help I tried to upload here but it shows errors. try this url: https://we.tl/t-t92S5rlCzD

From what I’ve found, the K2B has three revisions; mine is REV 2.2 (it’s printed right on the PCB). Looks like they swapped the RAM from DDR4L to DDR3—mine has DDR3 chips on board—so that might be why it’s acting up. Kickpi’s site barely loads from China; I really dislike that company, the documentation is almost non-existent. I found some here: https://github.com/tan-zhihao1/kickpi-book/tree/master/h618/en Still, I want to crack the problem. With the current sale the 2 GB + 0 GB version is only 78 CNY (about 11 USD), which is hard to pass up. Thanks for getting back to me. K2B.zip

I dd the armbian.img > emmc. and remove my sd card still the same output

I dont think so. I can boot the official system “kickpi-k2b-ubuntu-jammy-desktop-xfce-linux-5.4.125-20250901.img” using this SD card

I am using this version "Armbian_community_25.11.0-trunk.334_Kickpik2b_trixie_current_6.12.47_minimal.img".

Any suggestions or solutions would be greatly appreciated. Thanks in advance!
