Boot stops on RPi4 yocto/hardknott (u-boot 2021.01)
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

You could try running 'git bisect' between these two versions to find the guilty commit.

Hello Morten, Start from bisecting a bad commit.
Then it will be easy to say what is wrong.

I did a git bisect. But the error is not a 100% reproducable so I must have taken a wrong turn somewhere during the bisect.
I think the solution is to just skip the 2021.01 release.
Thanks for your help.

Assuming it works with the later ones too. The other thing to check is what version of the RPi firmware you're using.
