NXP missing board.h file in fsl_flexspi_nor_boot.h

[DerekSnell]

This question comes from @Nadav from https://discord.com/channels/720317445772017664/883445396284772413/1118144085744681101

Hello everyone!
After updating the zephyr version to 3.1.0, mcuboot wont build.
it fails with the error:

In file included from /home/nadav/zephyrproject/zephyr/soc/arm/nxp_imx/rt/soc_rt11xx.c:20:
/home/nadav/zephyrproject/modules/hal/nxp/mcux/mcux-sdk/devices/MIMXRT1176/xip/fsl_flexspi_nor_boot.h:14:10: fatal error: board.h: No such file or directory

Before updating to the latest release, everything worked perfectly fine.
I came across this: #45559 is the solution provided by @Derek.Snell is the one i need to take into consideration?
I am working on a custom board based on mimxrt1172.

Thanks in advanced!

Hi Nadav,

Zephyr is about to release v3.4, so I am currently working from the tag v3.4.0-rc3. I was able to build the MCUboot application for the board mimxrt1170_evk_cm7 using the command below:

west build -b mimxrt1170_evk_cm7 ../bootloader/mcuboot/boot/zephyr

Modifying this example, I found the board.h reference in fsl_flexspi_nor_boot.h is not included. I confirmed this by renaming this board.h file, and the app still builds. The reason it is not included is the macro BOARD_FLASH_SIZE is defined.

Search the Zephyr tree for the BOARD_FLASH_SIZE macro, it is defined in the board's CMakeLists.txt file, using the line below:

zephyr_compile_definitions(BOARD_FLASH_SIZE=CONFIG_FLASH_SIZE*1024)

You mentioned you are building with a custom board. My guess is your CMake file is not defining this BOARD_FLASH_SIZE macro.

Let us know what you find, best regards

Hi Derek ,
Thank you for the post.

The suggested solution solved my problem.

Adding the line:
zephyr_compile_definitions(BOARD_FLASH_SIZE=CONFIG_FLASH_SIZE*1024)
To my custom board CMakeLists.txt file indeed solved my issue.

Thanks again, BR.
