Many people have done YAFFS on NOR and indeed there are some shipping products using this. YAFFS does not do erase suspend, so garbage collection is a bit slow. Still, it should be fine for testing purposes. Let's say you have a block size of 64kB. Each "chunk" needs 512 data bytes + 16 spare bytes = 528 bytes. Therefore each block can hold 64K/528 = 124 chunks. So, set chunksPerBlock to 124 and away you go! -- Charles > -----Original Message----- > From: yaffs-admin@stoneboat.aleph1.co.uk > [mailto:yaffs-admin@stoneboat.aleph1.co.uk] On Behalf Of > Michael Erickson > Sent: Wednesday, 12 January 2005 5:29 a.m. > To: yaffs@stoneboat.aleph1.co.uk > Subject: [Yaffs] Using YAFFS with an array of NOR flash. > > > Hello all, > > I am working on integrating the direct interface into our bootloader > environment.
