Bare metal gpio twiddling for RISC-V on rpi pico2

My little project this week was to try to a get bare metal RISC-V assembler coded GPIO twiddler working on a pi pico2. (Actually PICO2-W)
With little to no useful help from chatgpt 4o, I finally managed to get something working although it appears a regular daplink probe is a little flaky with the pico and openocd, maybe a pi pico programmed with daplink would be better?
