stack-test

A program that tests all of the STACK device’s functionality and peripherals (LED array, buzzer, temperature sensor and accelerometer) by performing all of the included supervisor calls.

Building

This program is provided as a cmake project in order to be run on any USB-enabled EFM32 based device supported by geckOS. 1 Make sure to set the variables FLASH_ORIGIN, FLASH_LENGTH, RAM_ORIGIN, RAM_LENGTH, either as command-line arguments (with the -D flag as below) or directly in the CMakeLists.txt file, depending on the microcontroller your device has and the size in flash and RAM of the compiled kernel.

$ mkdir build-release && cd build-release
$ cmake -DCMAKE_BUILD_TYPE=Release \
   -DFLASH_ORIGIN=0xa000 -DFLASH_LENGTH=0x6000 \
   -DRAM_ORIGIN=0x20001000 -DRAM_LENGTH=0x2000 ..
$ make

You should obtain an ELF file with debugging symbols named like the project, useful for disassembly and debugging, and a .bin file, to be transferred to geckOS’s mass storage device on bootloader start up.

The cmake project is based on efm32-base (link).
