Greetings. I’m trying to use an Ubuntu GDB to debug a binary compiled in Visual Studio 2017 / Visual GDB.
The “regular” GDB that I tried first was this one:
Copyright (C) 2016 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law. Type “show copying”
and “show warranty” for details.
This GDB was configured as “x86_64-linux-gnu”.Which I later found that different GDB’s are needed for different target platforms… So I did a ” sudo apt-get install gdb-arm-none-eabi” and tried this one (after copying the entire project from Windows to Linux via samba share):
gojimmypi@ubuntu:~/workspace/STM32-ST7735-standalone/VisualGDB$ /usr/bin/arm/bin/arm-none-eabi-gdb -d ./

(gdb) file ~/workspace/STM32-ST7735-standalone/VisualGDB/Debug/STM32-ST7735.bin
“/home/gojimmypi/workspace/STM32-ST7735-standalone/VisualGDB/Debug/STM32-ST7735.bin”: not in executable format: File format not recognized
(gdb)As you can see, I am still getting the same “file format not recognized” error. Any suggestions as to what I might do to make this work? This is the same binary image that gets flashed to the device, right?
In this case, I am targeting the STM32F103 found in the “STM32_Smart_V2” using a J-Link
https://github.com/gojimmypi/STM32-ST7735
http://wiki.stm32duino.com/index.php?title=STM32_Smart_V2.0
Everything works fine from within Visual Studio… I’m just trying to see if “alternate debug” methods are possible 🙂
Thanks in advance. Cheers.

gojimmypi@ubuntu:~/workspace/STM32-ST7735-standalone/VisualGDB$ /usr/bin/arm/bin/arm-none-eabi-gdb -d ./ -f Debug/STM32-ST7735

Reading symbols from Debug/STM32-ST7735…done.This helped:
C:\SysGCC\arm-eabi\bin\arm-eabi-readelf.exe -a STM32-ST7735

In case someone wants to do something similar:
start OpenOCD (in this case using JLink and stm32f100):
sudo openocd -f /usr/local/share/openocd/scripts/interface/jlink.cfg -f /usr/local/share/openocd/scripts/target/stm32f1x.cfg
launch GDB:
/usr/bin/arm/bin/arm-none-eabi-gdb -d ./ -f ~/workspace/STM32-ST7735-standalone/VisualGDB/Debug/STM32-ST7735
then from (gdb) prompt, select elf file (no elf extension!) and connect to OpenOCD port 3333:
file ~/workspace/STM32-ST7735-standalone/VisualGDB/Debug/STM32-ST7735 target remote localhost:3333
