Hello Alex, have you tried to set "u-boot,spl-boot-order" in choosen node?
Take a look into: doc/device-tree-bindings/chosen.txt Best regards Johann Neuhauser -----Ursprüngliche Nachricht----- Von: U-Boot [mailto:u-boot-boun...@lists.denx.de] Im Auftrag von Alex Kiernan Gesendet: Mittwoch, 1.

We have MMC2 as our boot device, with no MMC1 (and hence not present in the DTB). Once we're into full U-Boot this is all okay, we get the board's MMC2 appearing as mmc0 and everything's fine. My problem's during SPL, where the boot device is MMC2, the code tries to lookup by devnum (which is 1 because it numbers from 0 at this point), which doesn't exist. I'd expected aliases to work, but we don't seem to lookup up by alias, only index, so I don't have any way that I can see of overriding it. If I make this change, then everything works (with the addition of an an alias for mmc1 = &mmc2): diff --git a/common/spl/spl_mmc.c b/common/spl/spl_mmc.c index 0b2f059570..b7544ba183 100644 --- a/common/spl/spl_mmc.c +++ b/common/spl/spl_mmc.c @@ -131,7 +131,7 @@ static int spl_mmc_find_device(struct mmc **mmcp, u32 boot_device) } #if CONFIG_IS_ENABLED(DM_MMC) - err = uclass_get_device(UCLASS_MMC, mmc_dev, &dev); + err = uclass_get_device_by_seq(UCLASS_MMC, mmc_dev, &dev); if (!err) *mmcp = mmc_get_mmc_dev(dev); #else But that feels like a pretty fundamental change to make across every board and I've no real idea if that would even be the right thing to do, or if I should be trying to fix this some other way. -- Alex Kiernan _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
