 Updating U-Boot
Can you link to instructions on updating the u-boot. I think this is it here.
 sync after umount?
Using a sync after the umount is completely redundant right? After umount there is no block part in the kernel doing any caching, so there is nothing to actually sync anymore. So I think the sync should be removed. Bram
What are the benefits of booting from SD? Does it improve the performance in terms of speed and/or non-SD RAM/ROM memory usage of the device? Pander 11:05, 20 July 2009 (UTC)
 Take care with inode size when formatting ext2 partitions
I noticed uboot was having difficulty reading the cards I had formatted using my linux box. Google to the rescue, I found the following discussion: Uboot Discussion
So apparently uboot is currently only reading ext2 partitions with an inode size of 128. Recent default is 256. I wonder if the mkfs with our distros defaults to 128?
Workaround: mke2fs -I 128 /dev/sd*
Hopefully uboot will be updated to allow default inodes to be recognized.
