Hi ,am new to this. Am trying to change Atmel AT49BV642D to SST 39VF6401B on embedded board with processor AT91Rm9200. What all steps i should follow to get this chip work properly.Any changes to be done on Uboot? Now its showing as follows
physmap phymap.c platform flash device: 00800000 at 10000000 physmap-flash physmap-flash.0: map_probe failed
Linux kernel is 2.6. Compiler Arm-Linux gcc .
I have added the following to jedec_probe.c
{ .mfr_id = MANUFACTURER_SST, .dev_id = SST39VF6401B, .name = "SST 39VF6401B", .devtypes = CFI_DEVICETYPE_X16, .uaddr = MTD_UADDR_0xAAAA_0x5555, .dev_size = SIZE_8MiB, .cmd_set = P_ID_AMD_STD, .nr_regions = 1, .regions = { ERASEINFO(0x10000,128) } }
