Hi, I'm working on a project where we recently upgraded to Yocto/hardknott.
After the upgrade to U-Boot 2021.01 the boot stops at switch to partitions #0, OK mmc0 is current device Scanning mmc 0:1... and then nothing more happens. Sometimes resetting power will cause the RPi4 to boot - but not always. I then downgraded to U-Boot 2020.07 and the RPi4 boots every time. I will be looking at the commits between 2020.07 and 2021.01 - but I'm not really sure what to look for - any ideas? Best regards Morten
