Due Debug

My notes on debugging a arduino Due with a cheap stm32 in ubuntu 16.04, for future reference, and to help whoever needs to do the same.

Material:

1. Arduino Due.
2. stm32 arduino board (~2$) with stlink v2 programmer (~2$) from aliexpress.
3. Micro USB cables.
4. Connectors.

Steps:

STM32 Firmware

Get Mitek's wonderfull stm32 CMSIS-DAP firmware: https://github.com/x893/CMSIS-DAP

Download the .hex file in "CMSIS-DAP/Firmware/STM32/hex/CMSIS-DAP-V1-F103.hex"

To Convert to a bin file using:

$ arm-none-eabi-objcopy -I ihex --output-target=binary CMSIS-DAP-V1-F103.hex firmware.bin

Upload to smt32

1. Install stlink: https://github.com/texane/stlink

2. $ make release

3. (for system wide install)

   $ cd build/Release; sudo make install

4. upload using stlink or platformio

   $ st-flash --format ihex write CMSIS-DAP-V1-F103.hex

Upload Blink with debug symbols (-g) to due using platformio

$ cd ..

$ cd due

$ sh upload.sh

Use edbg to test programming and verifying the firmware:

https://github.com/ataradov/edbg

Download the repo:

$ make all

connect wires:

Program:

$ ./edbg -p -t atmel_cm3 -f myduefirmware.bin

Verify:

$ ./edbg -v -t atmel_cm3

Debug with OpenOCD

$ apt install openocd

$ openocd -c "interface cmsis-dap" -f due.cfg

Using gdb interface

$ arm-none-eabi-gdb example.elf

(gdb) target remote localhost:3333

Remote debugging using localhost:3333

Using Clion gdb interface
