# Shared Espressif + esptool layout and flash parameters for CMake scripts.

#
|
|
# Prerequisites (callers must do this first): - include(nuttx_kconfig.cmake) -
|
|
# nuttx_export_kconfig(${DOTCONFIG}) - BINARY_DIR and SOURCE_DIR set (for
|
|
# FLASH_ENC_KEY_PATH)
|
|
#
|
|
# Defines set by including this file:
|
|
# CHIP_SERIES - Chip string for esptool -c (from CONFIG_ESPRESSIF_CHIP_SERIES)
|
|
# BL_OFFSET - Bootloader/app base offset for MCUboot & simple boot
|
|
# EFUSE_FLASH_OFFSET - Virtual eFuse blob offset in flash (from Config.mk EFUSE_FLASH_OFFSET)
|
|
# EFUSE_OFFSET - Alias for EFUSE_FLASH_OFFSET (for mkimage.cmake compatibility)
|
|
# MCUBOOT_APP_OFFSET - NuttX signed image offset (primary or secondary OTA slot)
|
|
# FLASH_SIZE - Flash size (e.g. 2MB, 4MB), for merge_bin/elf2image -fs
|
|
# FLASH_MODE - Flash mode (dio, dout, qio, qout), for elf2image -fm only
|
|
# FLASH_FREQ - Flash speed (e.g. 40m), for elf2image -ff/write_flash -ff
|
|
# FLASH_ENC_KEY_PATH - Resolved path to CONFIG_ESPRESSIF_SECURE_FLASH_ENC_HOST_KEY_NAME
|
|
# (empty if unset; relative paths checked vs BINARY_DIR then SOURCE_DIR)
