Hi,
We are testing using the Octavo RED board with OSD32MP157c SoC
(stm32mp157c).
We are using vanilla u-boot 2022.10(in basic mode without TF-A) and
Linux kernel version 6.0.x.
I have ported the devicetree's from Octavo combined with upstream
stm32mp1 boards.
But we are facing issues with running the eMMC in DDR50 mode, works fine
in normal 50Mhz mode (without the mmc-ddr-3_3v in dts).
It works fine though, with the ST u-boot and ST Linux kernel.
One further note is it seems to work fine, when mounting a squashfs (aka
readonly) in DDR50.
But ext4 fails with:
root@osd32mp1-red:~# mount /dev/mmcblk0p7 /media/
