Not that I know of. I have been looking thoughtfully at Ultibo: https://ultibo.org/ It is a bare-metal FreePascal development environment for the RasPi 1 to 3B. I have not actually tried to build anything yet and my Pascal skills are 30y rusty now (and they were never that great anyway, but they're better than my C skills ever were). I believe it is possible to get Ultibo to load and execute a monolithic ARM binary, so long as it meets some requirements. I was pondering trying to built a statically-linked executable of Aranym: https://aranym.github.io/ Aranym already runs on the RasPi using Rasbian: https://sites.google.com/site/beebox68k/news/beepi10 But by the same token it ought to be possible to do this with SimH or anything else... -- Liam Proven – Profile: https://about.me/liamproven Email: lpro...@cix.co.uk – gMail/gTalk/gHangouts: lpro...@gmail.com Twitter/Facebook/LinkedIn/Flickr: lproven – Skype: liamproven UK: +44 7939-087884 – ČR (+ WhatsApp/Telegram/Signal): +420 702 829 053
