config EXAMPLES_MTDRWB
tristate "MTD R/W buffer test"
default n
depends on (MTD_WRBUFFER || MTD_READAHEAD) && BUILD_FLAT
select BCH
---help---
Enable the MTD R/W buffer test example.
NOTE: This example uses some internal NuttX interfaces and, hence,
is not available in the kernel build.
if EXAMPLES_MTDRWB
config EXAMPLES_MTDRWB_PROGNAME
string "Program name"
default "mtdrwb"
---help---
This is the name of the program that will be used when the NSH ELF
program is installed.
config EXAMPLES_MTDRWB_ARCHINIT
bool "Architecture-specific initialization"
default n
---help---
The default is to use the RAM MTD device at drivers/mtd/rammtd.c.
But an architecture-specific MTD driver can be used instead by
defining EXAMPLES_MTDRWB_ARCHINIT. In this case, the
initialization logic will call mtdrwb_archinitialize() to obtain
the MTD driver instance.
if !EXAMPLES_MTDRWB_ARCHINIT
config EXAMPLES_MTDRWB_ERASESIZE
int "Size of one erase blocks (simulated)"
default 4096
depends on !EXAMPLES_MTDRWB_ARCHINIT
---help---
When EXAMPLES_MTDRWB_ARCHINIT is not defined, this test will use
the RAM MTD device at drivers/mtd/rammtd.c to simulate FLASH. In
this case, this value must be provided to give the size of one erase
simulated erase blocks one MTD RAM device.
The size of the allocated RAM drive will be:
EXAMPLES_MTDRWB_ERASESIZE * EXAMPLES_MTDRWB_NEBLOCKS
config EXAMPLES_MTDRWB_NEBLOCKS
int "Number of erase blocks (simulated)"
default 32
depends on !EXAMPLES_MTDRWB_ARCHINIT
---help---
When EXAMPLES_MTDRWB_ARCHINIT is not defined, this test will use
the RAM MTD device at drivers/mtd/rammtd.c to simulate FLASH. In
this case, this value must be provided to give the number of erase
blocks in MTD RAM device.
The size of the allocated RAM drive will be:
EXAMPLES_MTDRWB_ERASESIZE * EXAMPLES_MTDRWB_NEBLOCKS
