    ARM Linux Paging Problems


    Recently I've upgraded a flash card from 16 MB to 32 MB along with RAM from 32MB to 64MB on a device that I've been playing with.

    Now my Kernel seems to be having issues - which I have assumed to be some issue with the memory mapping. The memory modules have been tested and do as expected.

    The kernel and boot loader are being run on an LM7A404 machine.


    Any assistance would be helpful as I seem to be at a loss. I've reconfigured the APEX configurations for the flash file system from:

    Code:
    CONFIG_DRIVER_JFFS2_BLOCKDEVICE="nor:0x40000+0xfc0000"
    to

    Code:
    CONFIG_DRIVER_JFFS2_BLOCKDEVICE="nor:0x40000+0x1fc0000"
    And for the general configuration:

    Code:
    # 
    # General Setup 
    # 
    CONFIG_CROSS_COMPILE=arm-linux- 
    CONFIG_CC_OPTIMIZE_FOR_SIZE=y 
    # CONFIG_SMALL is not set
    # CONFIG_DEBUG_LL is not set 
    CONFIG_SPINNER=y
    CONFIG_ATAG=y 
    CONFIG_DISABLE_MMU_AT_BOOT=y 
    CONFIG_ATAG_PHYS=0xc0000100 
    CONFIG_APEX_VMA=0xcd000000 
    CONFIG_KERNEL_LMA=0xc1000000 
    CONFIG_SDRAM_BANK0=y 
    # CONFIG_SDRAM_BANK1 is not set
    # CONFIG_CLCDC is not set

    Attached is the crash log
