Aha my DTS (based on robimarco) has booted now hopefully it gets easier here

Building 6.1 Openwrt kernel

been meaning to ask a bit of a dummies guide on how you are setting up the build environment and what changes you are introducing into your main code?
Im guessing you are going to / have a mx4200v2 fork too for these tweaks ?

Currently this is for V2 and yeah I have a fork,

To setup build environment it's all on the Openwrt GitHub page

Here's the Initramfs

https://file.io/dBNnyBMEuSJJ

This should get you up and running

Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

Run make to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system

My fork

Right this one boots and doesnt crash (yet)

So are there any specific files you need from the Linksys image or do they need building ?

Board2.bin and board-xiaomi_ax3600.ipq8074, board-xiaomi_ax3600.qca9889

I'm looking for something similar to these files, we need them

Nothing for board
