  • Backup program for NAND-flash

    oooops :loudly_crying_face:


    flashed via dreamup and serial cable, i wanted to try again to create the backup and now...



    Zitat


    root@dm7020:/var/tmp# prova
    *** bad block list: 012c8000 012cc000 012d0000 012d4000 012d8000 012dc000 012e0000 012e4000 01384000 01388000 0138c000 01390000 01394000 01398000 0139c000 013a0000 01538000 0153c000 01540000 01544000 01548000 0154c000 01550000 01764000 01768000 0176c000 01770000 01774000 01778000 0177c000 01780000 01820000 01824000 01828000 0182c000 01830000 01834000 01838000 0183c000 (39 blocks, 624 kB total)
    root@dm7020:/var/tmp#


    i already flashed again through web-interface and lan cable... and the 39 bad blocks are always there...
    any idea if/how could i solve this? :grinning_squinting_face:

    And yes, there is one more test, if you dare smile Restore the backup and see if it works. Worst case is that you will have lost the contents on the flash and have to start all over again, maybe even having to flash using the serial cable. Best case is that it seems to be OK, and you will have to run it for a few days to make sure that nothing was broken


    that's what you were not supposed to ask :smiling_face_with_horns: just joking :grinning_squinting_face:


    restored the backup via lan (through web interface).. my dm7020 is not starting anymore... black screen and the "II" symbol on the lcd display, even switching it on with the down button pressed.


    i go to find out where i put my serial cable... :grinning_squinting_face:

    this is the report with the verbose option :


    and the size of the new backup created is the same as yesterday:

    root@dm7020:/media/cf# ls -all
    -rw-r--r-- 1 root root 34586144 Feb 12 15:39 backup.nfi


    and ngc1927's NAND flash backup (with 1 bad block) filesize is 34569248, as to say -32 -2blocks.

    does this mean 1 block is always skipped creating the backup?


    if you need other tests... :winking_face:

    ooops :grinning_squinting_face:


    hadn't paid attention to this:

    The program, as it stands, does not try to skip empty blocks, so the resulting nfi file will be quite big. My full size files end up at 34603072 bytes, expect 32 bytes less for the 7020, and each bad block will subtract 16896 bytes (I think) from the total length.


    that's ok, then!


    I'm gonna check if my NAND has bad blocks

    thanks noggie
    just tried the ipk on my 7020, with a lightly modified cvs in flash from 06/02/2006


    seems to be working :grinning_squinting_face: :


    root@dm7020:/media/cf# ls -all
    drwxr-xr-x 5 root root 1024 Feb 11 22:29 .
    drwxr-xr-x 17 root root 0 Feb 7 21:23 ..
    -rw-r--r-- 1 root root 34586144 Feb 11 22:30 backup.nfi

    drwxr-xr-x 3 root root 1024 Oct 7 21:40 usr

    is it normal the backup size is 34 Mb?

    any help? :grinning_squinting_face:
