Hi there, I ve long been using the sd card as a storage device on my mini2440, but lately I ve been looking at some high-speed stuff, so the nand is appealing once again! Does anyone know how to move the ext image created by openembedded over to the nand? I know how to move the jffs2, but when it decompresses it spits out tons of errors and its really slow... Is there any way of putting a non-compressed fs on nand? Thanks Paul

Ext file systems depend on regular block devices, you can't just copy it over an mtd device and expect it to work. What you can do is mount the ext image to a directory and then use the program mkfs.jffs2 to build a jffs2 flash file system, but I'm not sure if disabling all compressors will result in an uncompressed image, often people say that is faster to have decompression on your fs than transfering the whole information from mtd.
Thanks Lint, has anyone found a way to avoid the errors you get when unpacking a jffs2? The default OS on the mini2440 is so damn fast in booting up... Thanks Paul
The default OS use the yaffs2, it is common at MTD device, you can use UBIFS too, it's heard with better feature, but who know it. I think yaffs2 is enough.
thx, will try! btw, does yaffs2 work with uboot?
If you just boot OS, any bootloader is ok. It is in depended with yaffs2.
