I am relatively new to openwrt.
I followed these instructions which work fine and installed a snapshot firmware version.
After use for a while I tried to update some packages (day job is serious about keeping software up to date and patching, etc). I learned that a snapshot version does not allow that as snapshots lock packages to a specific version.
So I thought I'd install a release version. Chose 22.03.5. From the above link I simply changed the wget argument from that shown to
Proceeded to download, gunzip and copy with dd. Upon reboot it looks ok until hanging at
Waiting for root device PARTUUID=141b0bcd-02
I thought I might need to change some of the boot parameters shown in the link above but I don't know to what value, or how to make persistent. I can see the expected firmware from running 'ext4ls mmc 0:1'
I'm not sure what next steps I could take to troubleshoot so hope that help may be available from you in this forum.
