AM29LV065D FLASH read, erase, program?

/dev/mtd2 shows up. I added it via my file system project (i.e., @mtd2,c,90,2). The CFI probe seems to work, and reports the partitions correction:

ISI flash device: 1000000 at 1000000

Probing for chip type

phys_mapped_flash: Found 1 x16 devices at 0x0 in 16-bit bank

Amd/Fujitsu Extended Query Table at 0x0040

Using buffer write method

phys_mapped_flash: CFI does not contain boot bank location. Assuming top.

number of CFI chips: 1

cfi_cmdset_0002: Disabling erase-suspend-program due to code brokenness.

Using ISI specific partition definition

Creating 4 MTD partitions on "phys_mapped_flash":

0x00200000-0x005f8000 : "ROMfs"

mtd: Giving out device 0 to ROMfs

0x00000000-0x00200000 : "kernel"

mtd: Giving out device 1 to kernel

0x00700000-0x00800000 : "Flash FS"

mtd: Giving out device 2 to Flash FS

0x00800000-0x01000000 : "FPGA Cores"

mtd: Giving out device 3 to FPGA Cores

Is it sufficient that the devices show up as follows?# ls -la /dev/mt*

crw------- 1 root root 90, 0 Jan 1 1970 /dev/mtd0

crw------- 1 root root 90, 1 Jan 1 1970 /dev/mtd1

crw------- 1 root root 90, 2 Jan 1 1970 /dev/mtd2

crw------- 1 root root 90, 3 Jan 1 1970 /dev/mtd3

brw------- 1 root root 31, 2 Jan 1 1970 /dev/mtdblock2

I enabled the block and char mtd drivers in the kerel config...I just can't seem to nip this one.

hi mikewest,

does /dev/mtd2 exist ... as a character mode device? and did you enable the char

mode mtd driver in you kernel?
