The CMSIS enables consistent and simple software interfaces to the processor for interface peripherals, real-time operating systems, and middleware. The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series and specifies debugger interfaces. You don’t need to use/buy external debug probe.Īrduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences ST Nucleo F401RE has on-board debug probe and IS READY for debugging. You can switch between debugging Tools & Debug Probes usingĭebug_tool option in “platformio.ini” (Project Configuration File). Instructions and configuration information. Please click on compatible debug tool below for the further You will need to install debug tool drivers depending on your system. Compilation database compile_commands.json.

I'd advice you to build and flash some simple example from libopencm3-examples (like this one), and try to debug it with GDB. Everything works as expected.Īlso it should be mentioned that I'm using libopencm3 in my firmware, so it also might have some influence over success of operation. /cm3/vector.c:68Ħ8 for (src = &_data_loadaddr, dest = &_data Īnd then use usual debugging commands, like step, next, print var, bt, etc. In my case, GDB shows me (on start): GDB connected. Now you can use usual GDB commands for debugging. Save it as gdb.sh and run it like this (once you powered up your board): $. $GDB -ex "target extended localhost:4242" $elf_file #!/bin/shĮcho "Please provide elf-file for debug symbols" >&2 Of course, st-util must be installed, as that script uses it. Perhaps if you follow my instructions, it will work out for you, too.įirst of all, provide next flags to GCC when building your firmware: # Debug flagsĬFLAGS += -Os -g -fno-schedule-insns -fno-schedule-insns2ĬFLAGS += -fno-omit-frame-pointer -funwind-tables I have a similar setup (except for CLion), and I'm able to debug my STM32 board via STM32F4DISCOVERY (which has ST-LINK v2 on it). Lastly, if I use configuration of GDB: Default (Bundled) I don't expect it to work well, but it actually gets further and allows a very limited functionality of pausing/resuming (but with absolutely no other abilities) and does not complain about the symbols elf symbols load properly direct from command line. If I use arm-none-eabi-gdb direct from command line ( /usr/bin/arm-none-eabi-gdb verified), things work as normal, breakpoints, stepping, etc. gdbinit but gdbinit seems ignoredįurthermore, it does indicate a connection to st-util running remotely, but I am unable to execute any commands (breakpoints, stepping, pause, etc) except for terminate - which does seem to terminate it. Symbol file: /home/malachi/temp/mbed_test/mbed-os-program/BUILD/NUCLEO_F401RE/GCC_ARM/mbed-os-program.elfįrom CLion, no matter what I do, I consistently get this for Console: Cannot configure GDB defaults: No symbol table is loaded. In the GDB Remote Debug config panel, I've set: GDB: /usr/bin/arm-none-eabi-gdb I read through GDB Monitor commands in CLion providing good insight, but I am having a slightly different issue:
