# # For a description of the syntax of this configuration file, # see the file kconfig-language.txt in the NuttX tools repository. # config EXAMPLES_MEDIA tristate "Media test" default n ---help--- Enable the media test. This test simply writes values onto the media hidden behind a character driver and verifies that the media can be successfully written and read. This low level test is useful in the early phases of the bringup of a new block or mtd driver because it avoids the complexity of a file system. This test uses a character driver and cannot directly access block or mtd drivers. This test is suitable for use EEPROM character drivers (see nuttx/drivers/eeprom), or with block drivers wrapped as character drivers (see nuttx/drivers/bch) int ret = bchdev_register(, , false); MTD drivers need an additional wrapper layer, the FTL wrapper must first be used to convert the MTD driver to a block device: int ret = ftl_initialize(, mtd); ret = bchdev_register(/dev/mtdblock, , false); if EXAMPLES_MEDIA config EXAMPLES_MEDIA_DEVPATH string "Character driver path" default "/dev/mtd0" ---help--- This is the full path to the character driver that is used to access the media. This test is suitable for use EEPROM character drivers (see nuttx/drivers/eeprom), or with block drivers wrapped as character drivers (see nuttx/drivers/bch) int ret = bchdev_register(, , false); MTD drivers need an additional wrapper layer, the FTL wrapper must first be used to convert the MTD driver to a block device: int ret = ftl_initialize(, mtd); ret = bchdev_register(/dev/mtdblock, , false); NOTE: This drivr path can be overridden when the application is executed by providing a differ device path on the 'media' command line. config EXAMPLES_MEDIA_BLOCKSIZE int "Block size" default 512 ---help--- This test will attempt to determine the block size of the underlying block or MTD driver using ioctl calls. This default value will only be used in the event that the test logic is unable to determine the underlying block size of the media. This value should match the block/MTD device's (erase) block size. config EXAMPLES_MEDIA_PROGNAME string "Program name" default "media" depends on BUILD_LOADABLE ---help--- This is the name of the program that will be use when the NSH ELF program is installed. endif
