Summary: ATmel spi flash card fails to be copied to

Details:

 

ATmel spi flash card fails to be copied to, The jumper is at Ic1, and stamp.c is edited like:

 

static struct mtd_partition bfin_spi_flash_partitions[] = {

        {

                .name = "bootloader",

                .size = 0x00040000,

                .offset = 0,

                .mask_flags = MTD_CAP_ROM

        }, {

                .name = "kernel",

                .size = 0x20000,

                .offset = MTDPART_OFS_APPEND,

        }, {

                .name = "file system",

                .size = MTDPART_SIZ_FULL,

                .offset = MTDPART_OFS_APPEND,

        }

};

 

static struct flash_platform_data bfin_spi_flash_data = {

        .name = "m25p80",

        .parts = bfin_spi_flash_partitions,

        .nr_parts = ARRAY_SIZE(bfin_spi_flash_partitions),

        .type = "at25df041a",

};

 

When booting the kernel and run the test,it would panic if copy a file to it:

Follow-ups

 

--- Michael Hennerich                                        2008-05-15 11:44:38

Fixed.

 

BTW: Atmel flash driver uses 4Kbyte sector erase size.

You need to tell this mkfs.jffs2 using

  -e, --eraseblock=SIZE  Use erase block size SIZE (default: 64KiB)
