mongoose-os-template

Mongoose os template with the following features:

• CMake with:
  • local quick compilation (run mos build first - to generate files, for examples configs)
    • ESP8266 and ESP32 - xtensa
    • Windows - VS C++
  • full mos build
• ESP32 on-chip debugging (GDB) with OpenOCD and JTAG

  1. build and flash MCU.

  2. Connect JTAG to MCU. I use ESP32 devkit\Wemos ESP32 Pro + FTDI FT2232H. Pinout (https://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT2232H.pdf):

     ESP32	JTAG
     GPIO 12 (TDI)	ADBUS1
     GPIO 13 (TCK)	ADBUS0
     GPIO 14 (TMS)	ADBUS3
     GPIO 15 (TDO)	ADBUS2
     GND	GND

     

     Optinally you can use the reset pin.

     TIP: If you use FT2232 (or FT4232H - 4 channels) you can use the second channel for TX\RX

     ESP32	JTAG
     RX	BDBUS0
     TX	BDBUS1

  3. run debug_start_openocd.bat. I usually do it by hand. You can reconfigure appropriate OpenOCD configuration inside the file.

  4. update .gdbinit and\or .gdbinit-command-line accordingly

  5. start debugger:

     • command line:
       1. start xtensa-esp32-elf-gdb.exe -x tools/.gdbinit-command-line build/objs/mongoose-os-template.elf (debug_start_gdb.bat)
     • CLion:
       1. Create GDB remote debug configuration. You can use OpenOCD Download & Run however you cannot configure it with additional params (as for now) - for example you have to merge config files into one (interface/ftdi/esp32_devkitj_v1.cfg, board/esp-wroom-32.cfg).
       2. Create custom tool (debug_copy_gdbinit.cmd) and run it before lunch - CLion does not allow to use local .gdbinit as for now so we copy it to %HOME%/.gdbinit before each run.
       3. Select config and press Debug (Alt + F5).
• Google test under windows build
• CLion tested
• other build, flash scripts
  • Look into tools folder

Some features are still in development
