config SPI_FLASH_VERIFY_WRITE

bool "Verify SPI flash writes"
|
|
default n
|
|
help
|
|
If this option is enabled, any time SPI flash is written then the data will be read
|
|
back and verified. This can catch hardware problems with SPI flash, or flash which
|
|
was not erased before verification.

config SPI_FLASH_LOG_FAILED_WRITE

bool "Log errors if verification fails"

|
|
default n
|
|
help
|
|
If this option is enabled, if SPI flash write verification fails then a log error line
|
|
will be written with the address, expected & actual values. This can be useful when
|
|
debugging hardware SPI flash problems.
|
|

config SPI_FLASH_ENABLE_COUNTERS

bool "Enable operation counters"

default 0
|

help
|
|
This option enables the following APIs:
|
|
|
|
- spi_flash_reset_counters
|
|
- spi_flash_dump_counters
|
|
- spi_flash_get_counters
|
|
|
|
These APIs may be used to collect performance data for spi_flash APIs
|
|
and to help understand behaviour of libraries which use SPI flash.

config SPI_FLASH_ROM_DRIVER_PATCH

bool "Enable SPI flash ROM driver patched functions"
|
|
default y
|
|
help
|
|
Enable this flag to use patched versions of SPI flash ROM driver functions.
|
|
This option is needed to write to flash on ESP32-D2WD, and any configuration
|
|
where external SPI flash is connected to non-default pins.

default SPI_FLASH_WRITING_DANGEROUS_REGIONS_ABORTS
|
|
help
|
|
SPI flash APIs can optionally abort or return a failure code
|
|
if erasing or writing addresses that fall at the beginning
|
|
of flash (covering the bootloader and partition table) or that
|
|
overlap the app partition that contains the running app.
|
|
|
|
It is not recommended to ever write to these regions from an IDF app,
|
|
and this check prevents logic errors or corrupted firmware memory from
|
|
damaging these regions.
|
|
|
|
Note that this feature *does not* check calls to the esp_rom_xxx SPI flash
|
|
ROM functions. These functions should not be called directly from IDF
|
|
applications.
