| 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-driver>, |
| <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-driver>, |
| <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. |
