### Disclaimer
-Given solution is included in `MCUboot` repository with purpose to demonstrate basic consepts and features of MCUboot library on Cypress PSoC 6 device. Applications are created per MCUboot library maintainers requirements. Implemetation differs from conventional and recomended by Cypress Semiconductors development flow for PSoC 6 devices. These applications are not recomended as a starting point for development and should not be considered as supported examples for PSoC 6 devices.
+Given solution is included in `MCUboot` repository with purpose to demonstrate basic consepts and features of MCUboot library on Infineon Technologies devices.
-Examples provided to use with **ModusToolbox® Software Environment** are a recommended reference point to start development of MCUboot based bootloaders for PSoC 6 devices.

### Solution description
There are two applications implemented:
-* MCUBootApp - PSoC6 MCUboot-based bootloading application;
-* BlinkyApp - simple PSoC6 blinking LED application which is a target of BOOT/UPGRADE;
+* MCUBootApp - MCUboot-based bootloader implementation;
+* BlinkyApp - simple blinking LED application which is a target of BOOT/UPGRADE;
-The default flash map for MCUBootApp implemented is next:
+Detailed description on each application is provided in dedicated files:
-* [0x10000000, 0x10018000] - MCUBootApp (bootloader) area;
-* [0x10018000, 0x10028000] - primary slot for BlinkyApp;
-* [0x10028000, 0x10038000] - secondary slot for BlinkyApp;
-* [0x10038000, 0x10039000] - scratch area;
+Bootloader - [MCUBootApp.md](./MCUBootApp/MCUBootApp.md)
+Test Application - [BlinkyApp.md](./BlinkyApp/BlinkyApp.md)
-The flash map is defined through sysflash.h and memory.c.
+Separate documentation is available for External Memory usage in mcuboot [ExternalMemory.md](./MCUBootApp/ExternalMemory.md)
-It is also possible to place secondary (upgrade) slots in external memory module. In this case primary slot can be doubled in size.
-For more details about External Memory usage, please refer to separate guiding document `MCUBootApp/ExternalMemory.md`.
+### Downloading solution
-MCUBootApp checks image integrity with SHA256, image authenticity with EC256 digital signature verification and uses either completely software implementation of cryptographic functions or accelerated by hardware - both based on Mbed TLS Library.
-
-### Downloading solution's assets
-
-There is a set assets required:
-
-* MCUBooot Library (root repository)
-* PSoC6 Peripheral Drivers Library (PDL)
-* Mbed TLS Cryptographic Library
-
-Those are represented as submodules.
+Since libraries required by mcuboot Infineon implementation are implemented as submodules following commands needs to be executed.
