Port of MCUBoot library for evaluation with Cypress PSoC 6 chips

Disclaimer

Given solution is included in MCUboot repository with purpose to demonstrate basic consepts and features of MCUboot library on Infineon Technologies devices.

Supported platforms

Solution description

There are two applications implemented:

• MCUBootApp - MCUboot-based bootloader implementation;
• BlinkyApp - simple blinking LED application which is a target of BOOT/UPGRADE;

Detailed description on each application is provided in dedicated files:

Bootloader - MCUBootApp.md Test Application - BlinkyApp.md

Separate documentation is available for External Memory usage in mcuboot ExternalMemory.md

Downloading solution

Since libraries required by mcuboot Infineon implementation are implemented as submodules following commands needs to be executed.

To retrieve source code with subsequent submodules pull:

git clone --recursive https://github.com/mcu-tools/mcuboot.git

Submodules can also be updated and initialized separately:

cd mcuboot
git submodule update --init --recursive

Building solution

Root directory for build is boot/cypress.

This folder contains make files infrastructure for building both MCUbootApp and sample BlinkyApp application used for Bootloader demo functionality.

GCC_ARM is only supported toolchain.

It is recommended to use ModusToolbox™ Software Environment which includes GCC Toolchain.

The default installation folder is expected by the makefile build system.

To use another installation folder, version of ModusToolbox™ IDE or another GCC Compiler, specify the path to a toolchain using the TOOLCHAIN_PATH parameter.

Below is an example on how to set toolchain path to the latest include with ModusToolbox™ IDE:

make clean app APP_NAME=MCUBootApp PLATFORM=PSOC_062_2M BUILDCFG=Debug FLASH_MAP=platforms/memory/PSOC6/flashmap/psoc6_swap_single.json TOOLCHAIN_PATH=c:/Users/${USERNAME}/ModusToolbox/tools_3.2/gcc

Python3 needs to be installed in system since build process required execution of prebuild and postbuild scripts in python.

Build environment troubleshooting

Following CLI / IDE are supported for project build:

• Cygwin on Windows systems
• unix style shells on *nix systems
• Eclipse / ModusToolbox ("makefile project from existing source")

Make - make sure it is added to system's PATH variable and correct path is first in the list;

Python/Python3 - make sure you have correct path referenced in PATH;

Msys2 - to use systems PATH navigate to msys2 folder, open msys2_shell.cmd, uncomment set MSYS2_PATH_TYPE=inherit, restart MSYS2 shell.

This will inherit system's PATH so should find python3.7 installed in regular way as well as imgtool and its dependencies.
