Hi, thought I'd cross post here as I imagine some of you have the same issue. Anyone here found a slim console only image with Debian (or Ubuntu) that plays well with LEDscape?

Ryan, it sounds like you may have worked this out. However, I think you simply needed to disable the HDMI in the uEnv.txt file.

seriousmumbo commented 9 years ago

Yes, kernel bone70 works with HDMI disabled. I'm curious as to why this is necessary? I like the HDMI =).

mykolasmith commented 9 years ago

It's because LEDscape uses those GPIO pins that would otherwise be used for HDMI. You can't have your cake and eat it too ;)

Speaking of tradeoffs: I noticed that the ledscape dtb breaks sd card hotplug.

seriousmumbo commented 9 years ago

Is the .dts source for the dtb available?

seriousmumbo commented 9 years ago

I created a new dtb, it should work well with the newer kernels (tested with bone70). Advantages include: sdcard hotpug working, hwrng, enhanced quadrature encoder pulse decoder, bandgap (chip temp) sensor, GPS cape and much much more:

My use case (one 24 pixel strip) is probably more limited than yours, so testing is in order.
