I asked ChatGPT with help about bare metal 32-bit ARM (For the Pi Zero W) C/ASM, emulated in QEMU for testing, and after the third iteration of “use printf for output” -> “there’s no printf with bare metal as target” -> “use solution X” -> “doesn’t work” -> “ude printf for output” … I had enough.
QEMU makes it pretty painless to hook up gdb just FYI; you should look into that. I think you can also have it provide a memory mapped UART for I/O which you can use with newlib to get printf debugging

Sounds like it’s perfectly replicated the help forums it was trained on.
That’s what tends to happen

The latter is what I tried, and also kinda wanted ChatGPT to do, which it refused
Did it at least try puts?
Can’t you just send prints to serial?
Yes, that was the plan, which ChatGPT refused to do
