Re: [U-Boot] MMC boot / mvebu / clearfog
Hi! Christoph Eggerwrites: > Indeeed, the following patch fixes MMC booting for me (and most > certainly breaks SD card booting) It actually seems to be somewhat more difficult. It worked because I had a old u-boot image at mmcblk0 at offset 1 block and a new u-boot at mmcblk0boot0. (old ~ before removing the +1). I guess u-boot gets loaded from the mmc0boot0 device (which is also where the SPL is from) and as soon as the post-SPL u-boot tries to access it's own bytes it falls over to mmcblk0. I have a working setup by dd if=u-boot-spl.kwb of=/dev/mmcblk0boot0 bs=512 dd if=u-boot-spl.kwb of=/dev/mmcblk0 bs=512 seek=1 skip=1 (skipping the first sector to keep the MBR alive and assuming it only contains SPL code anyway) Christoph -- 9FED 5C6C E206 B70A 5857 70CA 9655 22B9 D49A E731 Debian Developer | Lisp Hacker | CaCert Assurer signature.asc Description: PGP signature ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Hi! Christoph Eggerwrites: > hdr read sector 141, count=1 Looking at the binary it seems to have the expected magic at sector 140 == 0x28000 and the "wrong magic" at sector 141 == 0x28200 indeed. I guess this comes from SD cards where the kwb blob is written with 1 sector offset while on eMMC it has to be written directly to the start of the mmc device.

[U-Boot] MMC boot / mvebu / clearfog
Hi! MMC boot on the ClearFog (base) still seems to fail (uart boot works fine apart from uart detection). The SPL seems to finish successfully and jump to u-boot but there is no further output then. I'm trying to enable even more `DEBUG` but help is indeed welcome!
