Linux editing protip: instead of `sudo nano /path/to/file` use `sudo -e /path/to/file` after ensuring $EDITOR is something sane. Sudo will run your editor as your user on a temporary file which it will later copy over the actual file. This allows you to keep your editor configs on your user only and is arguably more secure.

nice one!

[@RochusKeller]

This is really great work, thank you very much! It's complete and explains the problem and the solution end-to-end even with the relation to the device tree, a suitable driver and test module and the tools used. This lecture is worth every second!

this is a great video. whoever picked that blue color, the dark blue, not the light blue, for text in a console, has better eyes than any human I have ever encountered, or has their monitor brightness up far too high.

[@MobiusHorizons]

very impressed with your content!!! I picked up the ice-pick dev-board, and it finally arrived, so I will be attempting to use that to follow along!

Great, thanks so much for this, it will help a lot! Just received my iCE40HX8K dev board (cheaper at Symmetry Electronics), and waiting for an Olimex iCE40-IO to go with it. The icoBoard is too expensive ($101!). Planning some simple logic and old CPU designs.

great vid, thanks, and good work too. Hope to be using it or something similar in the near future!

You just got a new subscriber. That was FANTASTIC!

Really great video!

[@SkyRiderJavelin]

always interesting well explained content ....

[@nikolavasovic]

Great job!

[@mlefe09]

Excellent!

[@aymen_dh2499]

Well done ..Still waiting for more FPGA videos

[@OpenTechLab]

+Aymen Din They will be coming soon!

Great video! I noticed that you had your oscilloscope probe set to x1 instead of x10 (your voltage was set to 20V/div instead of 2v/div). You should change that on your probe, as you otherwise limit the bandwidth of the probe significantly and you may not see the real ringing.

Like a super cypress usb loader :) I'd love the next generation of mainstream 'arduino/raspberry' type boards to be arm+fpga duos with oss toolchains. Emulate an NES? How about BE a 6502 :D

[@Aemilindore]

Really miss your videos

You make my brain hurt .... and I like it!

[@MichaelAddlesee]

Good work. Well done. BTW have you evaluated the Lattice Semiconductor: ICE40HX1K-STICK-EVN iCEstick Evaluation Kit?

[@edgeeffect]

It's a pity that you have to write a kernel module.... something like *cat firmware.bin >/dev/ice40-1* would make it all worth it.
