For a scientific space project I'm thinking about
including an FCode
interpreter into the onboard software.
The target system is a Leon3 processor (Sparc-V8) in FPGA with serial
port(s), spacewire and a few other interfaces.
I'm able to compile & run bare C applications (gcc cross-compiler), so
it seems to me that I don't need a real BIOS.
So you probably won't need SCSI or floppy drivers or any of the filesystems.
These can be disabled by editing config/examples/cross-sparc32_config.xml.
What kind of serial port is this, Zilog or PC (16550)?
Ideally the complete FORTH system should be in the
range of 32-40 kBytes...
That can be difficult to achieve, currently the full build is 150k C code +
100k Forth. I don't know how much of the Forth is needed. Taking out
unwanted drivers etc. could help a lot on C side, but down to 30-40k?
