Hi Detlev,
I have tried to create a jffs2-image of the linux-filesystem I wish to use, and then write it to my flash using "nand write.jffs2 100000 0 $(filesize)". But with no luck... Then I began to investigate the fundamental "ls" and "nand erase" commands, but neither there did I have any success. Below is a trace of what I've tried in order to get something working.
Are you really sure, your NAND gets accessed correctly both under U-Boot and Linux? Can you erase / write / readback some data under U-Boot by hand?
The problem has been solved... The reason that "ls" didn't work from u-boot, was that the boards' u-boot config-file included an erroneous nand-size:
#define CONFIG_JFFS2_NAND_SIZE 64*1024*1024
My board had only one configuration-file associated, but multiple nand-size configurations.
The jffs2-image problems were related to the endianess problems of mkfs.jffs2:

Thanks for all, Martin
