Hi, the router I'm working on at the moment, the DGN3500 lantiq platform, has a strange issue: it won't create or save the configuration. I see this in the logs:

What should I check? I think that it's creating rootfs_data in the correct place, but then the jffs2 filesystem starts looking for the end marker (deadc0de if i recall correctly) in the wrong place and therefore leaving the partition unformatted and leaving the config in the ramdisk. Any idea? -- Marcus905 GPG pubkey: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x1FC0ECC932FE5FAC _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
