Summary: ATmel at45df321d spi flash card also fails to be copied to

Details:

ATmel at45df321d spi flash card still fails to be copied to.

By selecting ic3 on the add-on spi board, and change the stamp.c like:

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 = "at45df321d",

};

The kernel built out would also fail at copy command:

Not a bug.

AT45DFxxx are DataFlash Devices they need a different driver.

<*> Support for AT45xxx DataFlash

< > Support most SPI Flash chips (AT26DF, M25P, W25X, ...)

-Michael

--- Mingquan Pan 2008-05-20 04:27:49

I have selected the items like above, so that the kernel can recognize the ic3

chip. It just has problem when copying.

--- Michael Hennerich 2008-05-20 06:39:29

Ok - I see.

Sorry - I should better read all emails to the bottom.

I have done a patch - I wait before I commit - for some clarification with

Atmel.

-Michael

--- Michael Hennerich 2008-05-20 08:40:21

Hi Grace,

can you try again.

The driver now prints out pagesize and erasesize.

mtd_dataflash spi0.1: AT45DB321x (4096 KBytes) pagesize 512 bytes erasesize

4096 bytes

both values needs to be given as arguments when cretin the jffs2 fs.

Here are the commands I used for testing.

root:/> eraseall /dev/mtd0

Yeah,the testing log of trunk head is about the same like above.
