A hobby CPU+stuff for FPGA.
For a TinyFPGA BX, which contains an iCE40.
- Build firmware
The firmware is compiled into a .vh file which will initialise the firmware memory with assembled code. The assembler and assemby language firmware are in shittyasm/app/Main.hs
Use Haskell stack:
cd shittyasm
stack build && stack exec shittyasm-exe > ../ram.vh
- Build FPGA bitstream
Uses apio to for the FPGA tool stack:
rm hardware.* ; apio build
# remove hardware.* because the build system doesn't detect changes
# in the firmware file, ram.vh
- Install bitstream into TinyFPGA BX
tinyprog --program hardware.bin
