So, I try to use nandsim with yaffs2 of large blocks. But I could not use. Can you tell me your versions of kernel and yaffs2, etc, if you are using nandsim. The reason that I try again. Thank you. -----Original Message----- From: ian@brightstareng.com [mailto:ian@brightstareng.com] Sent: Saturday, June 30, 2007 5:04 AM To: yaffs@lists.aleph1.co.uk Cc: Àü»óÀÏ (Sangil Jun) Subject: Re: [Yaffs] I want to use to nand flash emulator(nandemul2k) Sangil Jun, On Thursday 28 June 2007 02:59, Sangil Jun wrote: > I want to use nandflash emulator(nandemul2k) with yaffs2(2k > page). I just looked at mtdemul/nandemul2k.c -- this looks like some experimental code of Charles. It does not look compatible with the current MTD internals. > And I don't want to use to nandsim in the mtd source. Why not use nandsim? I just built, loaded, mounted, populated, unmounted, remounted, a Yaffs fs on nandsim and it seems to work just fine. I used the default nandsim settings for device emulation -- a small page, 8MB toshiba device. -imcd
