Set a breakpoint at main, (gdb) break main Now, we are all set to debug this program. Connect GDB $ arm-none-eabi-gdb (gdb) file helloworld

This command will wait for the debugger to connect on port 8090, here you can use any port. Now we can run the program with qemu-arm as, $ qemu-arm -L gcc-arm-none-eabi-10-2020-q4-major/lib -g 8090. We will compile this program using below command, $ arm-linux-gnueabihf-gcc -o helloworld helloworld.c -static -g Now lets try to create simple helloworld program, $ vim helloworld.c #include Ībove simple program prints helloworld and also prints addition of two numbers. Once you exported path, you can see arm-none-eabi-gcc is available in terminal. In this post, we will show you how you can debug the ARM binary compiled for some embedded ARM based target on the ARM QEMU, but this same things will be working for debugging on real target except how you run the binary on qemu.ĭownload latest ARM toolchain from, we downloaded gcc-arm-none-eabi-10-2020-q4-major-x86_2 which is the latest toolchain when writing this post.Įxport the toolchain path $ mkdir -p /home/myuser/workspaceĬopy the downloaded toolchain to this workspace directory, extract and export the bin path so we have the binaries in terminal path, $ tar xvf gcc-arm-none-eabi-10-2020-q4-major-x86_2 $ export PATH=$PATH:/home/myuser/workspace/gcc-arm-none-eabi-10-2020-q4-major/bin In our previous two posts, “How to use gdb for debugging application programs” and “Using GDB to debug functions defined in another file in C” we have shown some basic steps for how you can use GDB to debug your programs running on X86 based desktops.
