How can I put multiple JFF2 filesystems on a disk on chip (nftl or mtd)? I agree with dwmw2's analysis of flash filesystems. In a june 2002 email to Brendan Simon, David Woodhouse said: "Recently, JFFS2 has also had support added for NAND flash, and that should be about ready for use now. I'd want to spend three or four weeks on it before letting a customer have it (and as ever I wish somebody would just give my masters enough money to let me do that...:) There are some rough edges and it needs a lot more testing, but it's basically working already.We may need to fix the physical DiskOnChip driver to accept reads which aren't precisely 512 bytes long, if nobody's done so already -- but that should be simple enough." Ok then, where can I get this cut 'o code? Wil/Is this work(ing) through the MTD device or the NFTL? I wish I had the clout to get my company to pay DMW2 to do it, but they won't even spring for nor flash (not even More flash). My device has obscene application requirements. I need a compressed filesystem. I can see the eraseall and nftl_format utilities need to be more M-sys like. I may be able to help with this. Dtyree
