The hardware ran ok before and could use jffs2 without errors but as I added files it was slow and I could not make file systems on partitions which contained bad blocks. The new CVS code seems to be much quicker and I can erase, mount and copy files to my new filesystem without error. I have set up the specific driver to do soft ecc. I noticed that when I reboot the system and the filesystem gets mounted I get errors. The more writes that occur the more errors I seem to get. I ran a test for a week or so over the break which generated log files. A reboot after this produced thousands of errors but the filesystem seemed ok. The errors are something like Empty flash at 0x00469ffcb ends at 0x0046a000 or jffs2_scan_dirent_node(): Node CRC failed on node at 0x0046a7f0 read 0xffffffff calculated 0xdec8161b I was wondering if any of you could shed any light on this.
