Development Environment
This demo is targeted towards the Infineon XMC4700 Relax Kit board, with 2048 kB internal Flash EEPROM and 352 kB internal RAM.
These demo programs are configured for building with CMake, to showcase the use of the OpenBLT CMakeLists.txt interface targets.
To program the bootloader into the internal flash, the on-board J-Link debugger interface can be used, in combination with the Segger J-Flash Lite utility. However, this is not required if you have another means of programming the internal flash.
Toolchain configuration
To build the demo programs it is assumed that CMake, Ninja, and the ARM GNU Toolchain are installed on your PC and available at the system PATH. You can run the following commands to check if this is the case:
cmake --version ninja --version arm-none-eabi-gcc --version
Building and programming the Bootloader
Before the bootloader can be used, it needs to be built and programmed into the XMC4700's internal flash memory. The steps in this section only need to be done once.
Start by generating the build environment using CMake. Open a command prompt in directory \Target\Demo\ARMCM4_XMC4_XMC4700_Relax_Kit_CMake\Boot\build and run the command:
cmake -G "Ninja" ..
To build the bootloader, run these commands from the same directory:
ninja clean ninja all
The output will look something like this:
C:\Work\software\OpenBLT\Target\Demo\ARMCM4_XMC4_XMC4700_Relax_Kit_CMake\Boot\build>ninja clean [2/2] Cleaning all built files... Cleaning... 1 files. C:\Work\software\OpenBLT\Target\Demo\ARMCM4_XMC4_XMC4700_Relax_Kit_CMake\Boot\build>ninja all [83/83] Linking C executable openblt_xmc4700.elf text data bss dec hex filename 47508 228 22896 70632 113e8 openblt_xmc4700.elf
The bootloader program is now ready to be programmed into the internal flash memory of the XMC4700. Using your favorite programmer (i.e. OpenOCD or Segger J-Flash Lite), flash the bootloader using one of the following files, depending on what file type your programmer supports:
- \Target\Demo\ARMCM4_XMC4_XMC4700_Relax_Kit_CMake\Boot\build\openblt_xmc4700.elf
- \Target\Demo\ARMCM4_XMC4_XMC4700_Relax_Kit_CMake\Boot\build\openblt_xmc4700.srec
Building the Demo Program
Start by generating the build environment using CMake. Open a command prompt in directory \Target\Demo\ARMCM4_XMC4_XMC4700_Relax_Kit_CMake\Prog\build and run the command:
cmake -G "Ninja" ..
To build the demo user program, run these commands from the same directory:
ninja clean ninja all
The output will look something like this:
C:\Work\software\OpenBLT\Target\Demo\ARMCM4_XMC4_XMC4700_Relax_Kit_CMake\Prog\build>ninja clean [2/2] Cleaning all built files... Cleaning... 1 files. C:\Work\software\OpenBLT\Target\Demo\ARMCM4_XMC4_XMC4700_Relax_Kit_CMake\Prog\build>ninja all [52/52] Linking C executable demoprog_xmc4700.elf text data bss dec hex filename 13540 48 16708 30296 7658 demoprog_xmc4700.elf
The output file is
- \Target\Demo\ARMCM4_XMC4_XMC4700_Relax_Kit_CMake\Prog\build\demoprog_xmc4700.srec
