I can't seem to make a jffs2 image that u-Boot or the kernel can read. I know the nand read/write works because I've written kernels and ramdisks to nand (at many different locations) and they always read back and boot flawlessly. The JFFS2 image, on the other hand, makes u-boot take about 12 minutes to perform an "ls" on the jffs2 partition with hardware ecc disabled and fails completely with a bazillion ecc errors when hardware ecc is on.
I had a brainstorm earlier today and thought perhaps the compression type used by mkfs.jffs2 (1.5 and 1.6) wasn't enabled in the kernel so I went back and built a new kernel with every compression type built into the kernel that appears under the advanced compression heading. No change, same problems.
What I've used to create the jffs2 is an emdebian crossd build put into a directory (using sudo to get the device files etc) then the command line is
sudo mkfs.jffs2 -l -n -s 527 -e 0x4000 --pad=0x200000 -d myroot -o myroot.jffs2
I then copy that to my tftp directory, tftp to the s3c2410 device at 0x30800000 (ram is 0x30000000 to 0x40000000) and use:
nand write.jffs2 0x30800000 jffs2 0x2000000
I've also tried not specifying a page size (527 sounds odd) and using nand write instead of write.jffs2.
This is on a s3c2410 board and the nand routines came from the qt2410 patches at openmoko (like I sand, the nand write works perfectly with uImage and uRamdisk writes/reads).
Any idea where I'm going wrong?
