They always used to be very cagey about their documentation. I'm glad to see they're making progress -- at first glance it looks like we ought to be able to support the device with that information. That would be enough for using YAFFS or JFFS2 on it; if the translation layer isn't INFTL (as I suspect it isn't) then we'd also need docs on the new translation layer too, if we want to use it in DOS-compatible mode. > so now you have the doc, means you have plans to support it?:) Yeah -- given some sample hardware and a few spare weeks of spare time, I'd be happy to play :) It shouldn't be _that_ hard to make a driver for it which uses the core NAND code. See the existing drivers/mtd/nand/diskonchip.c for inspiration and turn up on #mtd of irc.freenode.net. If you're willing and capable then we can help you do it -- but if it turns out to be as much work to talk you through it as it would be to do it ourselves, then it's not going to work too well :) -- dwmw2 ^ permalink raw reply [flat|nested] 6+ messages in thread
