It should be :
case CFI_CMDSET_AMD_EXTENDED: case CFI_CMDSET_AMD_STANDARD: sect = find_sector(info, dest); flash_unlock_seq (info, sect); flash_write_cmd (info, sect, info->addr_unlock1, AMD_CMD_WRITE); sect_found = 1; break;#ifdef CONFIG_FLASH_CFI_LEGACY case CFI_CMDSET_AMD_LEGACY: flash_unlock_seq (info, 0); flash_write_cmd (info, 0, info->addr_unlock1, AMD_CMD_WRITE); sect_found = 1; break; #endif
to make it work for SST39LF040 which is only 4k per serctor.
Take a look at the latest version of the file in mainline. It already has such a patch integrated:
