I have been running ext3 on diskonchip2000 (using m-sys trueffs driver) for quite a while now and have not run into any problems yet, although I never did any asynchronous power off tests. I can boot off diskonchip using a special version of lilo and initrd. I would really like to try linux-mtd, however I am not quite sure if it is suitable for my use of the diskonchip. First of all, my application will create up to 32KB/s of data, and it will run for several hours (if not days at lower data rate). The diskonchip will be at least 384MB up to a maximum of 1GB. The OS (trimmed down LFS5.0, patched 2.4.27) is about 35M and lives in the same partition. Asynchronous power offs cannot be ruled out due to the nature of the instrument that will host the cpu board with the diskonchip. The mtd-jffs-howto refers to NFTL for diskonchip devices, but also talks about JFFS2 and how production worthy it is and it looks like some work has been done in the area of powercycle testing, but the link provided is not valid. What exactly does one get with *just* NFTL, i.e. does it makes sense to run ext3 on top of NFTL? Is NFTL production ready? There is also a comment that says JFFS2 does not work on DOC, but I assume that comment is old. What exactly is the status of JFFS2 for diskonchip devices? regards, AWS
