CONFIG_TEXT_SECTION_OFFSET¶
TEXT section offset
Type: hex
Help¶
If the application is built for chain-loading by a bootloader this variable is required to be set to value that leaves sufficient space between the beginning of the image and the start of the .text section to store an image header or any other metadata. In the particular case of the MCUboot bootloader this reserves enough space to store the image header, which should also meet vector table alignment requirements on most ARM targets, although some targets may require smaller or larger values.
