Hi!

Here's a SD card image that works for me. The topmost commit in the
same repository is the build configuration that was used to generate
it:

https://github.com/hackerspace/olpc-xo175-buildroot/commit/71783d599.patch

Note it is only going to boot off the SD card, because the root=
argument is hardwired in the devicetree. Sorry about that -- I built
the image before I noticed you're booting off an USB stick and I don't
have the resources to regenerate the image at the moment.

Your image does boot for me - after changing features on
filesystem.

	http://dev.laptop.org/~quozl/y/1gHh5m.txt (dmesg)

dumpe2fs of your image filesystem features; has_journal ext_attr
resize_inode dir_index filetype flex_bg sparse_super large_file
huge_file dir_nlink extra_isize metadata_csum, and flags;
signed_directory_hash.

dumpe2fs of my image filesystem features; has_journal ext_attr
resize_inode dir_index filetype extent flex_bg sparse_super uninit_bg
dir_nlink extra_isize, and flags; unsigned_directory_hash.

Our OLPC OS builder uses "mkfs.ext4 -O dir_index,^huge_file", from
e2fsprogs 1.42.5.

I'll look at the microSD card errors; by trying another one.

Success, too... after re-doing the filesystem with local mkfs.

One thing I noticed: olpc-battery/voltage_max_design is lower than
voltage normally reported by voltage_now.

I'll play with it some more

Best regards,
