A few pointers from recent history: http://lists.infradead.org/pipermail/linux-mtd/2014-September/055156.html http://lists.infradead.org/pipermail/linux-mtd/2014-September/055559.html If the question came up in other threads, though, I'm sure the answers were the same. BTW, there are sound solutions to this problem in Linux, and they are supported where possible. Some flash support a separate set of opcodes that always expect a 4-byte address. If we use these opcodes, we never have to do any persistent mode-switching. We only found that Spansion consistently supports these opcodes on all their flash, though.
