Laurent,
Thanks for the tip. When I tried this I get the following error from u-boot:
Scanning JFFS2 FS: ......... done. find_inode failed for name=usr ls: Failed to scan jffs2 file structure
Any other ideas?
Make sure the "partition" environment variable references the correct flash partition.

Hi Sam,

I’m seeing a strange issue with u-boot when I do a directory listing on a jffs2 filesystem. There are a couple of files that are listed numerous times. There appears to be a listing for each time the file was modified. FWIW, these files are modified one line at a time. I see this problem on both u-boot versions 1.1.4 and 1.2.0, but only with the latest kernel (2.6.21gum (gumstix)) but not with an older kernel (2.6.20-rt5gum (gumstix)). It looks like maybe some changes to the jffs2 in the latest kernel are not understood by u-boot?
Here is an example:
-rw-r--r-- 21 Thu Jan 01 00:01:03 1970 ally.conf -rw-r--r-- 44 Thu Jan 01 00:01:03 1970 ally.conf -rw-r--r-- 66 Thu Jan 01 00:01:03 1970 ally.conf -rw-r--r-- 85 Thu Jan 01 00:01:03 1970 ally.conf -rw-r--r-- 104 Thu Jan 01 00:01:03 1970 ally.conf -rw-r--r-- 122 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 140 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 159 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 180 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 210 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 235 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 268 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 283 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 298 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 319 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 335 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 348 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 361 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 375 Thu Jan 01 00:01:04 1970 ally.conf -rw-r--r-- 405 Thu Jan 01 00:01:04 1970 ally.conf
Once I boot into Linux, everything seems fine.
Any ideas or suggestions?
You might need to set CFG_JFFS2_SORT_FRAGMENTS in the U-Boot configuration. On a read/write partition, JFFS2 basically appends new data without overwriting old data. U-Boot will then need to sort data fragments to find out which ones are obsoleted by older ones.
