Hi,
U-Boot 2023.10 does not boot from uSD on RPi4. This has been found on openSUSE Tumbleweed. The only diff we need is: -CONFIG_OF_EMBED=y +CONFIG_OF_BOARD=y To use firmware provided Device Tree. But that should not affect the
mmc
behavior too much, I think.
I've been booting Fedora fine on a RPi4 BUT there's issues with the
display
turning off [1] when the accelerated display modules load (vc4) as a result of this patch set. Can you confirm if that's the same
problem
you're seeing?
No, that's not my problem. My issue is grub was not loaded by u-boot from
uSD.
It seems more like Simon's problem:

@Simon, can you check if the patch below fixes your boot problem on RPi4,
please?
This has been reported at least twice before. There is a fix [2] which is in my queue to apply.
Regarding the display problem, I got my rpi4 running again and Fedora installed, but I won't get back to it until the end of the week as I'm at osfc.
Regards, Simon
Thanks, Guillaume

'git bisect' points to:
commit c771e5b8c2a186fb072b6c6f571d4a3cc86efba9 Author: Simon Glass sjg@chromium.org Date: Thu Jul 27 15:54:28 2023 -0600
arm: rpi: Switch to standard boot Drop use of the distro scripts and use standard boot instead. We don't need to specify the mmc devices individually, since they
are
used in order from 0 to 2, and standard boot uses that order
anyway.
Signed-off-by: Simon Glass <sjg@chromium.org>
The following patch fixes the boot from uSD on RPi4 (not tested on
RPi3 nor RPi
Zero 2 W):
diff --git a/board/raspberrypi/rpi/rpi.env b/board/raspberrypi/rpi/rpi.env index 30228285ed..02210b97b5 100644 --- a/board/raspberrypi/rpi/rpi.env +++ b/board/raspberrypi/rpi/rpi.env @@ -74,4 +74,4 @@ pxefile_addr_r=0x02500000 fdt_addr_r=0x02600000 ramdisk_addr_r=0x02700000
-boot_targets=mmc usb pxe dhcp +boot_targets=mmc0 mmc1 mmc2 usb pxe dhcp
So, the comment from Simon " We don't need to specify the mmc devices
individually, since they are used in order from 0 to 2, and standard
boot uses that
order anyway" seems wrong for the RPi4 case.
Cheers, Guillaume
