# MCUBoot test application
|
||
|
|
This test is intended to compile a hello-world program taking into account
|
||
|
|
the existence of the MCUBoot bootloader at the first 32K in the ROM.
|
||
|
|
|
||
|
|
For this first support, a pre-compiled mynewt MCUBoot binary is downloaded at
|
||
|
|
compile time.
|
||
|
|
|
||
|
|
The goal is to produce an ELF file which is linked to be flashed at a
|
||
|
|
`BOOTLOADER_OFFSET` offset rather than the beginning of ROM. MCUBoot also
|
||
|
|
expects an image padded with some specific headers containing the version
|
||
|
|
information, and TLVs with hash and signing information. This is done through
|
||
|
|
the imgtool.py application, which is executed automatically by the build
|
||
|
|
system.
|
||
|
|
|
||
|
|
This test can be called using `make mcuboot` to produce such ELF file,
|
||
|
|
which can also be flashed using `make flash-mcuboot`.This command also flashes
|
||
|
|
the pre-compiled bootloader.
|
||
|
|
|
||
|
|
It's also possible to build and flash MCUBoot by following the instructions on
|
||
|
|
the MCUBoot repository either using mynewt or zephyr operating systems.
