Install icesprog

icesprog is a tool which can program FPGA. https://github.com/FPGAwars/toolchain-icesprog

sudo apt install git && git clone https://github.com/FPGAwars/toolchain-icesprog.git
cd toolchain-icesprog
./build.sh linux_i686
./build.sh linux_x86_64
./build.sh windows_x86
./build.sh windows_amd64

In my WSL setup, run ./build.sh windows_amd64 and restart command line tool. Type icesprog.exe will show following message.

if not showing anything, please check if you installed icesprog correctly.

write bitstream file onto FPGA

git clone https://github.com/wuxx/icesugar-pro
icesprog.exe icesugar-pro/demo/linux-with-litex.bit

Please make sure that you did connect FPGA on your PC.

This process will take some times, roughly 1 min.

After Done. We can disconnect the FPGA and prepare for the next step.

you can use drag and drop the bitstream file onto FPGA iCELink and it will do the same magic!

Prepare SD card for system image.

Take a microSD card, format it with FAT32 format. Assume SD card root is under mnt/sdcard

 cp icesugar-pro/linux/* mnt/sdcard/.

Insert the microSD card on the back side of FPGA.

After finishing copy system file into SDcard. Insert it on the back side of FPGA.

Connect the FPGA to PC and its led will glowing like this:

Check port number of the device.

Open Putty on the PC. In serial line, type what you see above. For example, my FPGA is on COM4.

Set Speed(baudrate) to 1000000 and type session name LITEX_LINUX and click save. Load LITEX_LINUX and click open.

Next time, you can simply load the session without typing again.

The Terminal will pop up like this:

Press reset button on the FPGA and the terminal will load correct booting information.

That is all! Next step should be building our own system though liteX.
