config EXAMPLES_CONFIGDATA
bool "Config Data example / unit test"
default n
---help---
Enable the Config Data example
if EXAMPLES_CONFIGDATA
config EXAMPLES_CONFIGDATA_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_CONFIGDATA_ARCHINIT. In this case, the
initialization logic will call configdata_archinitialize() to obtain
the MTD driver instance.
config EXAMPLES_CONFIGDATA_NEBLOCKS
int "Number of erase blocks (simulated)"
default 4
depends on !EXAMPLES_CONFIGDATA_ARCHINIT
---help---
When EXAMPLES_CONFIGDATA_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 nubmer of erase
blocks in the MTD RAM device.
The size of the allocated RAM drive will be:
RAMMTD_ERASESIZE * EXAMPLES_CONFIGDATA_NEBLOCKS
config EXAMPLES_CONFIGDATA_NLOOPS
int "Number of test loops"
default 1000
config EXAMPLES_CONFIGDATA_VERBOSE
bool "Verbose output"
default n
config EXAMPLES_CONFIGDATA_SILENT
bool "Silence the test details"
default n
