tristate "Media test"

---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);
|
|
|

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.

This is the name of the program that will be used when the NSH ELF

program is installed.
