Yes
I just want to thank you for debugging this. Based on the timestamps of your other post, it looks like you posted a solution just hours before I was setting mine up. Prior to finding that thread, I was starting to think I'd received a faulty CM4.
To DFRobot:
In December 2021, someone from DFR reported in another thread that a firmware update would be released shortly & it seems that never happened. Can you please update your openwrt release to solve this problem and bring the linux kernel up to date?
I wrote the previous prior to reading the entire thread. Replacing the .dat and .elf liles from 2022.03.0-rc5 does indeed allow my new cm4 to boot.
I'm looking forward to the update that was promised 7 months ago.
Can someone confirm if this issue is why my new cm4 8gb emmc 1 gb ram with wireless will not boot, however my cm4 lite 1gb ram no-wireless boots and functions without issue on my DFR0767? Is there any workaround that does not involve a full manual openwrt install?
