White screen about gba_vscode_basic

[JamieDStewart]

Hi I've not run this on a linux system, only tested on Mac and Windows. I'd imagine that the "linux" set up options in both launch.json and tasks.json would be similar to the Mac setup options.
I've not tried debugging with visualboyadvance, or retroarch mgba core. I know that mGBA versions after 0.6.2 dont work with the gdb debugging set up I'm using here.
Can you confirm that a gba rom is built? You should be able to simply build the gba file by following ctrl+shift+p and running the task 'make release'.
Could you build the rom that way and test?

Build is fine.
The problem is with main.c code - it just displays whitescreen, was it supposed to do so, though?
Tested even on an online emulator (http://endrift.github.io/gbajs/)
Every other demo I've thrown at it is fine. Tried both the prebuilt .gba from repo and building main.c

[JamieDStewart]

The code displays a full screen Serpinski style of visual effect that repeats every few pixels.
There is no pre-built GBA ROM in this repo?
When you are building this what is the output from the console that you receive?
I have tested this ROM image with the online emulator you linked and the version I have built under release works in this emulator as expected.

Edit: That problem probably has nothing to do with your repository but devkitARM or something else
