I have been given PDFs of the errata information including 2.0 fixes by TI. I haven't been given any instructions or indications that it is proprietary information - I'm told it is on the TI web site. Do you want me to share it on the list? The cache issue has been fixed BTW. There are also four new (to me) errata against 1.0, 1.1 and 2.0 revisions - one of which is fixed in 2.0.
