I have not seen any chips with those dimensions. I think it should be bootable by DM355 RBL but you may need changes to u-boot or Linux mtd / yaffs2 to support the larger eraseblock size. Maybe someone else could comment. -- Jon Povey, Design Engineer jon.po...@racelogic.co.uk | +44(0)1280 825983 > Racelogic is a limited company registered in England. Registered number 2743719 .
