I understand that you are working with a IcoBoard
using a Raspberry Pi.

& Dave Vandenbout.

This was 3 hours which you can see in 43 sec.
I am using Chris Felton rhea and Jan's MyHDL.

I programmmed the ICE40-HX8K with catboard.bin obtained
after running the "python catboard_blinky_host.py --build"
I see the led blink at 1 per sec.
When you send 02de 0000 2000 ca04 0000 ff00
over the serial port at 115200 you should see

Using the catboard.v & catboard.pcf and the Lattice
iCEcube2 which provides catboard_bitmap.bin all works as
