Hello,

We are using 64MB RAM and 8MB flash and for the flash we are partitioning like this.

static struct mtd_partition bf5xx_partitions[] = {

{

  name: "Bootloader 1 MB",

  size: 0x100000,

  offset: 0,

},{

  name: "Default Kernel 512 KB",

  size: 0x80000,

  offset: 0x100000,

},{

                name: "VoIP Kernel 5.5 MB",

                size: 0x580000,

                offset:0x180000,

        },{

  name: "JFFS2 1 MB",

                size: 0x100000,

                offset: 0x700000,

}

};

but while opening a file of 30KB from flash using fopen it gives the error as "Used by the MMU to signal a CPLB miss on a data access" and the complete trace is as.

Data access CPLB miss
