I have been trying to make uboot boot my choice of distro (using ext2) on an SD card for quite a while without success. I had done it in the past with FAT+ext2 partitions, but never with a single ext2 partition. As a matter of fact, uboot had never been able to show the contents of my SD card's ext2 partitions. So I did some googling and found a discussion that seemed to relate to my problem: http://www.nabble.com/Problems-with-ext2ls---SD-ts22728281.html#a22756563
I tried the following: mke2fs -I 128 /dev/sd* copied a rootfs from one of the working distros, started uboot, mmcinit, and lo and behold, ext2ls listed the contents of the partition, and uboot booted it! I added the info to the discussion of the Booting_from_SD page, but I thought I'd bring it up here as well since I haven't seen this discussed in the wiki or in these lists. Is this well known? Do we know if there is a uboot capable of booting cards partitioned by modern mkfs? Russell Dwiggins
