What about flashes that say they have CUI (Command user interface) and SR (Status register)? what are CFI commands? are they 8bit, 16bit? if you have 2 chips giving you a 32bit databus, does it write out the same command on the high lane and the low lane? I've noticed LART connects address and data lines to flash in positions most convienent to route. Does this break any CFI functionality? ------- End of Forwarded Message To unsubscribe, send "unsubscribe mtd" to majordomo@infradead.org
