This demo is targeted towards the Olimex EM-32G880F128-STK board, with 128 kB internal Flash EEPROM and 16 kB internal RAM.
To program the bootloader into the internal flash on the EFM32G880 microcontroller, the Segger J-Link JTAG interface was used. However, this is not required if you have another means of programming the internal flash.
To compile the demo programs with Codesourcery G++ Lite (Target OS EABI), you can invoke the make utility from the command line.
Before the bootloader can be used, it needs to be built and programmed into the EFM32G880's internal flash memory. The steps in this section only need to be done once.
Batch files are added to aid in building the software program. First clean the bootloader program by double-clicking the file “\Target\Demo\ARMCM3_EFM32_Olimex_EM32G880F128STK_GCC\Boot\cmd\clean.bat”. Next, build the bootloader program by double-clicking the file “\Target\Demo\ARMCM3_EFM32_Olimex_EM32G880F128STK_GCC\Boot\cmd\build.bat”. The output should look like:
+++ Compiling [hooks.o] +++ Compiling [main.o] +++ Compiling [boot.o] ... +++ Linking [openbtl_olimex_efm32g880.elf] ... +++ Build complete [openbtl_olimex_efm32g880.bin]
The bootloader program is now ready to be programmed into the internal flash memory of the EFM32G880. Using your favorite programmer, flash the bootloader using one of the following files, depending on what file type your programmer supports:
