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?

OK", but "nand bad" still returns that all the blocks are bad. thanks, Paul
