MCUBoot application supports overwrite and swap upgrade modes for XMC7200 and XMC7100 platforms.
NOTE: In case of swap upgrade mode and when swap status partition area is located in work flash its required to fill the status partition with 0xFF before flashing the MCUBootApp.hex. As shown on the example below.
Following commands can be used as an example to build a project
Overwrite mode
make clean app APP_NAME=MCUBootApp PLATFORM=XMC7200 BUILDCFG=Debug FLASH_MAP=platforms/memory/XMC7000/flashmap/xmc7000_overwrite_single.json PLATFORM_CONFIG=platforms/memory/XMC7000/flashmap/xmc7200_platform.json CORE=CM0P APP_CORE=CM7 APP_CORE_ID=0
make clean_boot app APP_NAME=BlinkyApp PLATFORM=XMC7200 BUILDCFG=Debug FLASH_MAP=platforms/memory/XMC7000/flashmap/xmc7000_overwrite_single.json PLATFORM_CONFIG=platforms/memory/XMC7000/flashmap/xmc7200_platform.json CORE=CM7 CORE_ID=0 IMG_TYPE=BOOT IMG_ID=1

Swap mode
make clean app APP_NAME=MCUBootApp PLATFORM=XMC7200 BUILDCFG=Debug FLASH_MAP=platforms/memory/XMC7000/flashmap/xmc7000_swap_single.json PLATFORM_CONFIG=platforms/memory/XMC7000/flashmap/xmc7200_platform.json CORE=CM0P APP_CORE=CM7 APP_CORE_ID=0

Build parameters description: `
XMC7000 internal flash boot module can be used in secure configuration. A complete description and instructions for configuring a secure boot can be found in reference manual AN234802.
MCUBoot makefile supports secure image build configuration for XMC7200 and XMC7100 devices. To prepare a secure MCUBoot image, the user must configure the public key and specify the appropriate parameters for the TOC2 structure in the cy_si_config.c, cy_si_key.c files and execute the make command with the additional variables USE_SECURE_MODE=1, SECURE_MODE_KEY_NAME=<name>.
Step to generate custom RSA2048 keys: cysecuretools -t xmc7200 create-key --key-type RSA2048 -o ./keys/cypress-test-rsa2k.pem ./keys/cypress-test-rsa2k.pub --format PEM
Step to generate cy_si_key.c file: cysecuretools convert-key -k ./keys/cypress-test-rsa2k.pub -o ./platforms/utils/XMC7000/cy_si_key.c --fmt secure_boot --endian little
Previous two steps can be executed with single Makefile command. make gen_secure_cfgs PLATFORM=XMC7200 SECURE_MODE_KEY_TYPE=RSA2048 KEY_NAME=cypress-test-rsa2k
Step to run MCUBootApp build with secure flash boot config make clean app APP_NAME=MCUBootApp PLATFORM=XMC7200 BUILDCFG=Debug FLASH_MAP=platforms/memory/XMC7000/flashmap/xmc7000_overwrite_single.json PLATFORM_CONFIG=platforms/memory/XMC7000/flashmap/xmc7200_platform.json CORE=CM0P APP_CORE=CM7 APP_CORE_ID=0 USE_SECURE_MODE=1 SECURE_MODE_KEY_NAME=cypress-test-rsa2k
