Cannot access MTD device after booting from NAND.

Other Parts Discussed in Thread: TVP7002, THS7303, TVP5146, THS7353

I am loading the DM365 filesystem from SD Card, and updating the kernel in the NAND flash using flash utils.  The u-boot and kernel can load from NAND, but then I cannot access the MTD device to write a new kernel or boot environment. The error is /dev/mtd0: no such file or directory. When I look in /dev there are no mtd* entries, and the kernel boot log contains no NAND initialization messages.  When I run tftpboot and nboot, the mtd* entries are created. If I press Reset on my DM365 board and type bootm (without nboot), mtd is still available. Can you tell me why mtd is not created in these conditions?

    1. Have you configured linux MTD module.

    2. Did kernel detect the nand and mtd module.

    . Could you post the Kernel Boot log(dmesg).

     

    Regards

    My kernel config file contains the following entries:

    The kernel boot log contains only one reference to NAND/MTD - trying to access a JFFS2 ROMFS.
