This is great! Baremetal debugging is a really nice idea. I liked it. |

Not actually. Some errors in Makefile and/or make.sh. I'll try again later and do a review. |

Maybe related to nash version... Some incompatible changes happened recently.. |

Did you installed last nash version? |
|
nash-git-r578.bca7991-1 from AUR, but I removed it and built a clone repo. Same error. |

I copied my
termimplementation from EnzOS and theprintfimplementation of libc from SmallerC to run the example debugger (#1 still unnamed as xxx) in bare metal. The script to build was part copy-pasted from other project of my own too.Below is an screenshot of qemu:
The code of
regs.cis the same (with exception that printf I'm using do not support tabs, then registers are separated by spaces).Why I'm doing this? Because it would be very cool if we could build the debugger to run in a host OS (linux and so on) and on bare metal also.
But we'll need to find a good project layout and abstractions to make it work. Some way to separate system-dependent and system-independent code.
The code is a mess... It was only a hack/PoC and do not need a review from your side.
