Hi all,

In config/check_config.cmake there is a following code:

tfm_invalid_config((MCUBOOT_UPGRADE_STRATEGY STREQUAL " DIRECT_XIP " OR MCUBOOT_UPGRADE_STRATEGY STREQUAL "RAM_LOAD") AND TFM_PARTITION_FIRMWARE_UPDATE)

So looks like FWU is not supported when DIRECT_XIP or RAM_LOAD upgrade strategies are used.

But then in FWU code I see a lot of checks for DIRECT_XIP or RAM_LOAD, for example in fwu_bootloader_get_image_info:

#if !defined(MCUBOOT_DIRECT_XIP) && !defined(MCUBOOT_RAM_LOAD) && \

!defined(MCUBOOT_OVERWRITE_ONLY)

What is the point of these checks if it is impossible to compile FWU code with DIRECT_XIP Because of check in config/check_config.cmake?
