Hi there,

 

You are right, I made a mistake. Here’s the updated instructions that work for me:

 

$ cd ~/zephyrproject/zephyr

$ source zephyr-env.sh

$ west build -b qemu_x86_64 samples/hello_world/

$ cd build/

$ ninja debugserver

 

and then in another terminal

 

$ /opt/zephyr-sdk/x86_64-zephyr-elf/bin/x86_64-zephyr-elf-gdb build/zephyr/zephyr.elf

(gdb) target remote localhost:1234

(gdb) dir ~/zephyrproject/zephyr/

(gdb) continue

 

So it’s a matter of using Zephyr’s SDK gdb and passing it as a parameter the path to build/zephyr/zephyr.elf

Thank you!

But it seems cant load the symbol, so how to compile the debug elf files?

BTW: there are two elf files exist in build dir, zephyr.elf and zepyhr-qemu.elf, what is the difference?

The qemu_x86_64 target is configured to use two cores and SMP by default.

Now SMP only supported on xtensa, arc and x86 arch, but it seems more diffculte to run on xtensa and arc becasue of no boards.

so anybody can tell me how to launch a smp run environment on x86 arch? thank you!
