Currently I’m working on getting a minimal PC style BIOS together and booting C code from my FPGA designs. This is separate to the customised C tool chain I use for 64-bit development, so I may release a fork of a legacy compiler (which is also a bit more complete than my own) to go with it.
Once this is complete I should be able to progress more rapidly with improved CPUs and then eventually with starting to port more of my operating system. The operating system won’t run on my current chipset though, I decided to moving to testing on smaller, 8-bit soft CPUs so I could ensure the base hardware & BIOS layers would be free from the pitfalls of larger CPUs.
This obviously doesn’t mean work on my 64-bit stack is obsolete or retired, just that I’ll finish some more basics before doing more work.
