I've been trying to use the following GNU MCU Eclipse QEMU releases to do unit tests for ARM Cortex binaries.
https://gnu-mcu-eclipse.github.io/qemu/ https://gnu-mcu-eclipse.github.io/qemu/releases/ I compiled the very simple semi-hosting hello world sample in the gcc arm installation (from ARM download site). It's a basic `printf("Hello world!");` It runs ok on the Mac. i.e. displays "Hello world!" on the terminal that I run qemu from. However the same command line and exact same binary does not show any output when run on a Windows box (Win 10). I tried from MSYS2 bash shell and Windows Command Prompt, and both show no output. A bit of googling suggests that it displaying console output just doesn't work on Windows. Is that really true? Why can't Windows output to stdout? Surely it's technically possible, and not too difficult? Surely there must be a way to get stdout working Windows. What magic do I have to do to get this working? Thanks, Brendan.
