This blinky is based on the ULX3S-Blinky project from @Doctorwkt. This example blinks an LED using FPGA code.
It is assumed the yosys, nextpnr toolchain has been already installed. If not, see instructions here
Optionally copy a fresh ulx3s_v20.lpf constraint file.
# assume git clone to ~/workspace/
cd ~/workspace/ulx3s-examples/blinky/OpenSource
cp -f ../../doc/constraints/ulx3s_v20.lpf ./ # optionally copy an updated lpf file
On linux, the regular ujprog can be used:
make clean
make ulx3s.bit
../../bin/ujprog ulx3s.bit
For Windows WSL, there is no USB support so the linux ujprog will not work, but the Windows executable ujprog.exe can be used.
It is important to note that ujprog.exe should only be executed from a non-VoIFS directory in WSL (e.g. /mnt/c/somedirectory...) see ujprog troubleshooting and the discussion here.
# assume git clone to C:\workspace\
# Note ujprog.exe does NOT work when launching from WSL VoIFS, so we move to a DOS directory (/mnt/c/....)
cd /mnt/c/workspace/ulx3s-examples/blinky/OpenSource
make clean
make ulx3s.bit
../../bin/ujprog.exe ulx3s.bit
for the 12F on WSL:
# assume git clone to C:\workspace\
# Note ujprog.exe does NOT work when launching from WSL VoIFS, so we move to a DOS directory (/mnt/c/....)
cd /mnt/c/workspace/ulx3s-examples/blinky/OpenSource
make clean
make ulx3s.bit -f Makefile.12F
../../bin/ujprog.exe ulx3s.bit
