Hello, I'm using the imx27lite-v2 branch for our opensource imx27 board. Right now I'm trying to get the nand to work. I'm using a Micron 2Gb x8 part (p/n MT29F2G08ABDHC). When I do "nand info" I get "Device 0: NAND 256MiB 1,8V 8-bit, sector size 128 KiB" which is correct. mtdparts returns:
device nand0 <mxc_nand.0>, # parts = 4 #: name size offset mask_flags 0: IPL-SPL 0x00040000 0x00000000 0 1: kernel 0x00200000 0x00040000 0 2: rootfs 0x00b00000 0x00240000 0 3: userfs 0x0f2c0000 0x00d40000 0 active partition: nand0,0 - (IPL-SPL) 0x00040000 @ 0x00000000 defaults: mtdids : nor0=physmap-flash.0,nand0=mxc_nand.0 mtdparts: mtdparts=mxc_nand.0:256k(IPL-SPL),2m(kernel),11m(rootfs),-(userfs) But when I do other commands like fsinfo or ls I get "read_nand_cached: error reading nand off 0x2000 size 8192 bytes" errors. My questions are: should the current driver support this chip? Do I need to do anything else to prepare the mtd partitions? Is there a low level test I could run on the NAND? thanks, Paul
