You need to connect to USB1 (US1) connector to the host computer in order to program the board.

Download fujprog for your OS latest version of fujprog.

Extract fujprog to "any-folder" on your drive

MacOS: export PATH=[path-to-fujprog]:$PATH
Linux: export PATH=[path-to-fujprog]:$PATH
Windows Powershell: $ENV:PATH = "[path-to-fujprog];" + $ENV:PATH
Windows cmd.exe: PATH=[path-to-fujprog];%PATH%

You may want to rename fujprog name, for example on linux just rename fujprog-v46-linux-x64 to fujprog

cd path-to-fujprog
mv fujprog-v46-linux-x64 fujprog

Upload blink led for your board version

git clone https://github.com/ulx3s/blink.git
cd blink
fujprog blink_85f.bit

On linux you may need to add udev rule

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

Default size in Makefile is 85F - you can change it here:

https://github.com/ulx3s/blink/blob/main/Makefile#L69

make clean
make ulx3s.bit
make prog
