Running with the master j1a.bin, adding some code, then using `#flash build/nuc.hex` quitting and then `make -C icestorm` and `sudo iceprog icestorm/j1a.bin` results in a non-working image as well... just...

Well, is there something I could do to help? I'm newcomer to forth, but I already know I want swapforth in my labs, controlling my equipment.

This one's closed for me. @robot-army is it still broken at your end?

Works on livebooted Ubuntu 15.10 (if you enable universe and multiverse in "Software & Updates" first)

There are unused ram blocks, yes. I was thinking of using some to implement the deeper parts of the stacks for the j4a, to try to free up some of...

The j4a only has four sets of stacks - they round-robin through the ram and alu, which prevents concurrency problems. The arrangement means the alu could be pipelined, and that's...

I'm currently doing something similar - except using the j4a to spit out samples to a SPI connected DAC, but only at 2 kHz. (Could have gone much faster of...

Hmm, might have to ask James, I don't really either. But it's a bit of a kludge: it's possible now to change block SRAM in a FPGA bin file directly...

Write a little verilog machine to generate it as you will without swapforth entirely - starting from one of the example designs. Then, when that works as expected, modify j1a.v...

You can now just use `map! *`
