  • Question

  • Hi,

       I am trying to get 8 bit nand working ,i am even able to get the filesystem on nand but i am not able to set the Hive based settings .When i do the cold reboot the OS halts after checking the NAND blocks its not able to load the other drivers after this point.Could anyone help in solving this issue.

  • I am sorry for not having lucidity in ma question.

    I am trying to boot WINEC7 on Dm8148 custom board with NAND enabled.

    Nand details- its an 8 bit NAND with 8k page size and redundant bytes of 32 bytes in every 256 pages.though the WINEC7 BSP does not support 8 bit Nand device ,when i referred to WINEC7 persistent hive user guide i got to know this bsp supports the NAND manufacture which is in my board.

    So i thought i ll try making the required changes for the driver to detect the 8 bit nand device and I made the following changes in the BSP.

    BSPcfg.c

    FMd.c

    img_cgf.h

    cfg.c

    flashmenu.c

    enabled hive based registry settings and persistent hive based storage in catalog items.

    I was able to detect nand Manufacture ID and device ID and even able to read and write to it.but when i tried hive settings on it.

    I am able to get  Winec7 booted up with filesystem on NAND(system.hv and user.hv show the timestamp changes when i make any changes to the desktop wallpaper) but it is not able to survive the reboot .But when i erase 0-5 blocks using Eboot menu options of erasing NAND it boots up but with no folders saved created by me in the mounted volume region/folder.

    these are my NAND.reg file settings.

    As i am using Smart NAnd (I am using MDD+PDD layer).
