7054 support

Open fenugrec opened this issue 1 year ago • 1 comments

This is just a checklist of things to do. I am not planning on working on this myself. I expect 7054 will be very similar to either 7051 or 7055_35.

[x] look at ROM dump to see what RAM location is typically used for payload (in WE85C , looks like ffff8428 ; fairly typical ?) and other details pre-ramjump
[x] ensure sufficient RAM
[x] add register defines
[x] if necessary, add interrupt vectors
[ ] implement platform-specific code either as a subset of 7051, 7055_35 or as a separate file if too different
[ ] if reusing 7051 or 7055 flash code, make absolutely sure the needed constants (such as delays, loop counts etc) follow the 7054 datasheet
[ ] test

eh, I had some wastable time and took care of the easy stuff. Incomplete, will not work. https://github.com/fenugrec/npkern/tree/7054
