Help with LED Panel example

tonyd

Hi

I'm try to get the LED panel example working with my LogiBone and I've run into couple of problems.

http://valentfx.com/wiki/index.php?title=RGB_LED_Panel_Driver_-_by_Glen_Akins

This is my setup:

LogiBone 1.5.1
logibone_150429_ubuntu-14.04-console-armhf-2014-08-13.img

When I run "sudo ./setup_device-tree-slow.sh" to set up the device tree I'm getting the following error message:

"dtc: not found"

So it looks like the device tree compiler is missing from my installation or not working, can anyone help?

thanks

Tony

When using the 14.04 image there should be no need to use the setup_device-tree script since the driver and device tree setup is performed on boot. Unfortunately instruction provided by Glen does not work with 14.04 images since device-tree support changed,,and logibone 1.5.1 is a bit different on the loader side, from the one used in glen's work.
More-over Glen's use its own implementation of the GPMC interface on the FPGA side which does not work with latest GPMC drivers from the image. To get help on this specific example, you should contact glen through his webpage :

Another option is to use a derivative project on the logi-projects github (logi-matrix) but it will require to compile your bitstream. You can find informations on :
