Dissasembly and global variables not working with second debug environment (build_type = debug) #3708

Open dzid26 opened 1 year ago

dzid26 commented 1 year ago

Using a separate environment for debugging (as in the example) causes global variables to disappear and switching to assembly impossible.

Debugging session:

Globals are still accessible in debug console (e.g. p a returns 5 correctly)

Platformio.ini


[env]
platform = ststm32
board = bluepill_f103c8
framework = cmsis
upload_protocol = stlink

[env:bluepill_f103c8]
build_type = release

[env:bluepill_f103c8_debug]
debug_build_flags = -O0 -ggdb3              ; Apply no optimization to the code written.

build_type = debug
debug_tool = stlink

References: Original issue Similar issue OP issue is probably unrelated but linking for others.

Workaround is to point the environment switcher from default environment to the debug one.

This partially fixed itself somehow. Maybe VScode pushed an update?

The main.c can be found by disassembly if I explicitly switch to debug environment:

I am currently working with this repo if someone wanted to reproduce it.

Edit: It didn't switch to disassembly in "Auto" mode again. I needed to manually select a specific debug-type environment. Globals work most of the time, but occasionally they don't show up. Static variables, I believe, never show up.
