To detect blocks marked as bad it checks the 6th location of OOB area of first page, thus it seems it is not able to handle Micron devices properly. In fact these devices stores bad block marker in the first location of OOB of first or second page (for example see page 50 of MT29F1GxxABB data sheet). Am I misreading the datasheet? Could you help me to clear this point? Thanks in advance, llandre DAVE Electronics System House - R&D Department web: http://www.dave-tech.it email: r&d2@dave-tech.it
