Hi Tom, thanks so much for your reply. It is sad that nothing can be done.
I got a bare i.MX53QSB and I'd hate to trash the board over the lack of documentation and source.
Perhaps someone from NXP can help as this stuff must surely be archived internally.
Please ping me if anyone has a copy of the L2.6.35_11.09.01_ER_source_bundle.tar.gz
