Follow-ups
--- Vivi Li 2008-12-24 05:06:55
fails at somewhere between svn version 5713 and 5803...
--- Michael Hennerich 2008-12-28 17:46:23
I'm on vacation until Jan 8th - and I don't have any BF533 HW to test with me.
I committed a patch correcting a typo - likely fixing the issue.
Please test again.
Best regards,
Michael
--- Mingquan Pan 2008-12-29 04:04:53
Yes, looks good on bf533 stamp now.
--- Vivi Li 2008-12-30 01:40:30
Also OK on bf533-ezkit. Close this bug.
