@@ -118,7 +118,7 @@ SPI Flash Size
The SPI flash size is configured by writing a field in the software bootloader image header, flashed at offset 0x1000.
By default, the SPI flash size is detected by ``esptool.py`` when this bootloader is written to flash, and the header is updated with the correct size. Alternatively, it is possible to generate a fixed flash size by setting :envvar:`CONFIG_ESPTOOLPY_FLASHSIZE` in the project configuration.

If it is necessary to override the configured flash size at runtime, it is possible to set the ``chip_size`` member of the ``g_rom_flashchip`` structure. This size is used by ``esp_flash_*`` functions (in both software & ROM) to check the bounds.
