w00 BeagleWire!

Post by shapr » Mon Sep 10, 2018 6:32 pm

First Post!

But seriously, I bought a BeagleWire and convinced several coworkers to buy BeagleWire boards and we're doing a group FPGA learning class.

I've worked through some of the examples and I understand some things, but there's so much I don't understand.

My first question, I know the GPMC on the BeagleBone has a bunch of different modes, what's the mode it uses to talk to the RAM on the BeagleWire board?

This is determined by the devicetree settings for the GPMC.

See the following for the default configuration:

See this for the documentation of the devicetree fields for the GPMC:
