did you run the unlock utility like the other bug where you got this error ?
you cant assume the flash power up lock state. your test scripts have to run
the unlock utility before attempting any erase/programming.
--- Mingquan Pan 2009-06-04 05:12:42
Yes, here I need run flash unlock. And it is readable after doing that. Close.
