CMake - issue creating .elf file for embedded device

Hello
I am trying to compile a source file for an atmega328p (aka arduino uno). I managed to narrow down the issue, but don't know how to solve it.
This is the file I am trying to compile:
#include "../include/libgpio.h" #define TWSR_REGISTER_OFFSET 3 #define TWI_GYRO_ADDRESS 0b1101000 void main (void) { /* Disable interrupts. */ cli(); /* Reset watchdog. */ wdt_reset(); /* Clear WDRF in MCUSR */ MCUSR &= ~(1< When using those commands I am able to compile everything without issues:
avr-gcc -g -Os -mmcu=atmega328p -c gpio.c avr-gcc -g -mmcu=atmega328p -o gpio.elf gpio.o avr-objcopy -j .text -j .data -O ihex gpio.elf gpio.hex avr-size --format=avr --mcu=atmega328p gpio.elf sudo avrdude -c arduino -p m328p -P /dev/ttyACM0 -U flash:w:gpio.hex 
But when trying to replace the first two commands with the following CMake file it doesn't work:
cmake_minimum_required(VERSION "3.5") project("gpio" LANGUAGES "C") set(CMAKE_C_COMPILER "/home/yalishanda/Downloads/arduino-1.8.5/hardware/tools/avbin/avr-gcc-4.9.2") add_executable( "gpio.elf" "src/libgpio.c" ) target_compile_options( "gpio.elf" PRIVATE "-mmcu=atmega328p" PRIVATE "-std=c99" PRIVATE "-Os" ) 
I am still able to upload it onto the embedded device but I can see my software not being run; instead the device keeps on resetting. It is as if the binary generated by CMake isn't OK.
Does anybody have any idea's?

Automatic Compiling & Flashing of EFM32 Programs

I'm working a Machine Learning project, and I need to gather some data about the run-time of an EFM32 Microcontroller (EZR32LG).
After gathering a small dataset and realizing I need more (A lot more) data, I decided I'd automate the data-gathering process. I've managed to automate most of it, but I'm stuck on one thing.
Before, I used the Simplicity Studio IDE to manually compile, flash and run my code/device, however, since I need a lot of data, I'd like to automate this as well.
I tried reverse-engineering Simplicity Studio's makefiles etc., but I was a bit overwhelmed by them, so I'd like to try a different approach.
What commands do I need to run in order to compile, link and flash a binary for my microcontroller (Silicon Labs EZR32LG, SLWSTK6200A_EZR32LG)?
I've already found the command-line-tool I can use to flash my software (Simplicity Commander), but I'm a bit overwhelmed by all the GCC commands the IDE uses, are there any unnecessary commands/options or things that I could do without?
In case anyone is wondering, here are the commands Simplicity Studio seems to run in order to compile/link a program:
make -j4 all arm-none-eabi-gcc -g -gdwarf-2 -mcpu=cortex-m3 -mthumb '-DEZR32LG330F256R60=1' '-DDEBUG=1' -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/CMSIS/Include" -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/kits/common/bsp" -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/emlib/inc" -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/kits/common/drivers" -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/Device/SiliconLabs/EZR32LG/Include" -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/kits/SLWSTK6200A_EZR32LG/config" -O0 -Wall -c -fmessage-length=0 -mno-sched-prolog -fno-builtin -ffunction-sections -fdata-sections -std=c99 -MMD -MP -MF"src/bsort.d" -MT"src/bsort.o" -o "src/bsort.o" "../src/bsort.c" arm-none-eabi-gcc -g -gdwarf-2 -mcpu=cortex-m3 -mthumb '-DEZR32LG330F256R60=1' '-DDEBUG=1' -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/CMSIS/Include" -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/kits/common/bsp" -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/emlib/inc" -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/kits/common/drivers" -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/Device/SiliconLabs/EZR32LG/Include" -I"C:/SiliconLabs/SimplicityStudio/v3/developesdks/efm32/v2/kits/SLWSTK6200A_EZR32LG/config" -O0 -Wall -c -fmessage-length=0 -mno-sched-prolog -fno-builtin -ffunction-sections -fdata-sections -std=c99 -MMD -MP -MF"src/bsort_block_r129-130.d" -MT"src/bsort_block_r129-130.o" -o "src/bsort_block_r129-130.o" "../src/bsort_block_r129-130.c" arm-none-eabi-gcc -g -gdwarf-2 -mcpu=cortex-m3 -mthumb -T "External_Test.ld" -Xlinker --gc-sections -Xlinker -Map="External_Test.map" --specs=nano.specs -o External_Test.axf "./src/bsort.o" "./src/bsort_block_r129-130.o" "./emlib/em_cmu.o" "./emlib/em_gpio.o" "./emlib/em_system.o" "./CMSIS/ezr32lg/startup_ezr32lg.o" "./CMSIS/ezr32lg/system_ezr32lg.o" -Wl,--start-group -lgcc -lc -lnosys -Wl,--end-group arm-none-eabi-objcopy -O ihex "External_Test.axf" "External_Test.hex" arm-none-eabi-objcopy -O binary "External_Test.axf" "External_Test.bin" arm-none-eabi-size "External_Test.axf" 
Here's the makefile:
################################################################################ # Automatically-generated file. Do not edit! ################################################################################ -include ../makefile.init RM := rm -rf # All of the sources participating in the build are defined here -include sources.mk -include src/subdir.mk -include emlib/subdir.mk -include CMSIS/ezr32lg/subdir.mk -include subdir.mk -include objects.mk ifneq ($(MAKECMDGOALS),clean) ifneq ($(strip $(C_DEPS)),) -include $(C_DEPS) endif endif -include ../makefile.defs # Add inputs and outputs from these tool invocations to the build variables # All Target all: External_Test.axf # Tool invocations External_Test.axf: $(OBJS) $(USER_OBJS) @echo 'Building target: [email protected]' @echo 'Invoking: GNU ARM C Linker' arm-none-eabi-gcc -g -gdwarf-2 -mcpu=cortex-m3 -mthumb -T "External_Test.ld" -Xlinker --gc-sections -Xlinker -Map="External_Test.map" --specs=nano.specs -o External_Test.axf "./src/jfdctint.o" "./src/jfdctint_block_15.o" "./emlib/em_cmu.o" "./emlib/em_gpio.o" "./emlib/em_system.o" "./CMSIS/ezr32lg/startup_ezr32lg.o" "./CMSIS/ezr32lg/system_ezr32lg.o" -Wl,--start-group -lgcc -lc -lnosys -Wl,--end-group @echo 'Finished building target: [email protected]' @echo ' ' @echo 'Building hex file: External_Test.hex' arm-none-eabi-objcopy -O ihex "External_Test.axf" "External_Test.hex" @echo ' ' @echo 'Building bin file: External_Test.bin' arm-none-eabi-objcopy -O binary "External_Test.axf" "External_Test.bin" @echo ' ' @echo 'Running size tool' arm-none-eabi-size "External_Test.axf" @echo ' ' # Other Targets clean: -$(RM) $(OBJS)$(C_DEPS)$(EXECUTABLES) External_Test.axf [email protected] ' ' .PHONY: all clean dependents .SECONDARY: -include ../makefile.targets 
Automating the make command and substituting some things in the makefile wouldn't be too much of an issue, but when looking at the (600+ line) linker map is where I get a bit intimidated.
The same goes for the (200+ line) linker script...
I realize I'm building a debug version of my program, this is intentional and could change in the future.
I also forgot to mention that my previous automation (and the framework I'm integrating into) is written in Java, so Java solutions are a must.
Edit: I just noticed that the commands and the makefile are from different 'runs', if you replace the word 'bsort' in the commands-paragraph with the word jfdctint and keep in mind that the numbers in the filenames are more or less random, you'd get the commands for the run that matches the makefile.
I've also posted this over on IoT Stack Exchange here

According to this page it should be something like this arm-none-eabi-objcopy -I binary -O ihex filename.bin filename.hex 0 endnode over 3 years ago Use arm-none-eabi-objcopy from GCC for ARM, it has various input output options and BIN to HEX is supported (you supply target address as parameter, see the documentation). The GNU objcopy utility copies the contents of an object file to another.objcopy uses the GNU BFD Library to read and write the object files. It can write the destination object file in a format different from that of the source object file. The exact behavior of objcopy is controlled by command-line options. Note that objcopy should be able to copy a fully linked file between any two formats. llvm-objcopy is a tool to copy and manipulate objects. In basic usage, it makes a semantic copy of the input to the output. In basic usage, it makes a semantic copy of the input to the output. If any options are specified, the output may be modified along the way, e.g. by removing sections. objcopy can be used to generate S-records by using an output target of ` srec ' (e.g., use `-O srec '). objcopy can be used to generate a raw binary file by using an output target of ` binary ' (e.g., use -O binary). When objcopy generates a raw binary file, it will essentially produce a memory dump of the contents of the input object file. All objcopy can be used to generate S-records by using an output target of srec (e.g., use -O srec). objcopy can be used to generate a raw binary file by using an output target of binary (e.g., use -O binary). When objcopy generates a raw binary file, it will essentially produce a memory dump of the contents of the input object file. All symbols
