Hey, thanks for your advices. Adding "no-sd" really solved it. Best Regards Michael ________________________________________ Von: Ahmad Fatoum <a.fatoum@xxxxxxxxxxxxxx> Gesendet: Donnerstag, 6.

Please try adding no-sd to your eMMC device tree node and try again. I don't know why it's necessary, because falling back to MMC after SD fails is normal operation on all other hosts. I don't have the hardware, but I've seen that the recently added device trees that use the arasan, set this in barebox for the eMMC node. > > arasan-sdhci e0101000.mmc@xxxxxxxxxxx: registered as mmc1 > mmc1: detected SD card version 2.0 > mmc1: registered mmc1 > > both eMMC and SDCard work fine in Linux. So I think the Problem is some confuguration difference between Linux and barebox. > The MMC is from type MTFC8G but Linux detects it as > > [ 2.012122] mmc0: new high speed MMC card at address 0001 > [ 2.021129] mmcblk0: mmc0:0001 Q2J55L 7.09 GiB > [ 2.026355] Btrfs loaded, crc32c=crc32c-generic, zoned=no, fsverity=no > [ 2.027458] mmcblk0boot0: mmc0:0001 Q2J55L 16.0 MiB > [ 2.031509] mmcblk0boot1: mmc0:0001 Q2J55L 16.0 MiB > [ 2.039829] mmcblk0rpmb: mmc0:0001 Q2J55L 4.00 MiB, chardev (245:0) > > Unfortunattly I'm not very familliar with SDHCI, so I would apreciate any help. If it's indeed resolved by no-sd, this sound like a good occasion to dig deeper into the SDHCI. ;) Let me know if that works for you.
