One tiny possibility: I've managed to get something similar when playing with some spare DoCs I've got lying around (they're 8Mb 2001s salvaged from broken wince thin clients). On loading them with the MSys firmware image doc2.fff, which they suggest using with Linux, I get the following, which is similar to Simon's error (system is 2.2.17+CVS from infradead.org): Initializing MTD Layer Giving out device 0 to M-Systems DiskOnChip 1000 M-Systems DiskOnChip driver. (C) 1999 Machine Vision Holdings, Inc. M-Systems NAND Flash Translation Layer driver. (C) 1999 MVHI $Id: mtd-patch-2.2.17,v 1.3 2000/11/15 22:56:48 sjhill Exp $ NFTL_notify_add for M-Systems DiskOnChip 1000 NFTL_open ENODEV: thisNFTL = 0, minor = 23809, ip = c38c7320, fp = c37fbf68 ...which isn't really suprising as it's misdetecting the chip for something it isn't. Reloading the DoC firmware with the MSys bloatware fixes it however. (No, I haven't worked out how it misidentifies it yet). This sort of thing probably belongs in an FAQ/mini-HOWTO. I've made quite a lot of notes already(1) which I'll brush up and submit if anyone's interested or thinks it's worthwhile. cheers john (1) I'll leave out the bits about how to remove a DoC with a Swiss Army knife, but the bit about which pins you can bend or break without it mattering too much might be useful to other hardware thugs like myself ;-) To unsubscribe, send "unsubscribe mtd" to majordomo@infradead.org
