2026-02-26 13:06:08 Well, the next step is the big one. I can put code into the buffer, but can I run it yet? Will I need to muck about with page permissions, etc.? I've read the technical reference, and it seems like at boot time the high speed CPU does have all permissions on all pages, but I don't know yet whether the tool chain will have rewritten those or not. 2026-02-26 13:17:28 So the next test will be something very simple - a bit of code that just returns, or maybe puts a number on my stack (the monitor implements the stack in the RAM buffer, so it's accessible either from the monitor or from the buffer code) and returns. Then just successfully calling that code and getting back without crashing will be a "pass."
