SPICA Build Process

Generating the initial project

• STM32CubeMX
  • Makefile project
  • Use HAL libraries

Building with the Makefile

• GCC/G++ version 6.3.1
  • Relies on newlib
• Line added to linker option
  • "-specs=nosys.specs"
    • adds stubs for some libc syscalls
    • retargeted functions in lib/sys/sys.c
• Makefile also modified to use g++ and build C++ sources
• run "make" to build
  • make all → builds all code
  • make flash → flashes latest built binary using st-link (requires st-link debugger)
  • make erase → erases flash on chip
  • make program → build all code and then flash it
  • make -B → forces a new build regardless of updates

Using the serial monitor

• Run "cu -l /dev/ttyACM0 -s 115200" or "screen /dev/ttyACM0 115200"
  • Note: this is for Linux
• Any serial monitor will work
