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(<path-to-block-dirver>,
<path-to-character-driver>, 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(<N>, mtd);
ret = bchdev_register(/dev/mtdblock<N>, <path-to-character-driver>,
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(<path-to-block-dirver>,
<path-to-character-driver>, 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(<N>, mtd);
ret = bchdev_register(/dev/mtdblock<N>, <path-to-character-driver>,
false);
NOTE: This driver 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"
---help---
This is the name of the program that will be used when the NSH ELF
program is installed.
