> > Mr Nelson, > Thanks very much for helping me on this! I made sure the values you specified in the previous post are in the u-boot that I am compiling. At this point, u-boot goes all the way up to the point, (I believe) where it mounts the root filesystem, but it looks for mmcblk1p2, instead of using mmcblk0p2. I don't think there is anything wrong with my filesystem on mmcblk0, since as soon as I put my original u-boot.img back into the boot partition of mmcblk0, it boots all the way through. I believe that somehow, it starts looking for the wrong mmc device when I update u-boot.img .
I will put the boot output below: ================================================================================================== [ 2.220710] mmc1: BKOPS_EN bit is not set [ 2.228889] mmc1: new high speed MMC card at address 0001 [ 2.235147] mmcblk0: mmc1:0001 MMC04G 3.60 GiB [ 2.240184] mmcblk0boot0: mmc1:0001 MMC04G partition 1 2.00 MiB [ 2.246631] mmcblk0boot1: mmc1:0001 MMC04G partition 2 2.00 MiB [ 2.254065] mmcblk0: p1 p2 [ 2.258902] mmcblk0boot1: unknown partition table [ 2.265208] mmcblk0boot0: unknown partition table [ 2.325107] tilcdc 4830e000.fb: found TDA19988 [ 2.330398] [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).
