Charles, I found the branches. Can you clarify on how to browse the 
overlays?

Re: [Machinekit] frame buffer for Optocape in 3.8

2017-03-10 Thread Dean Gouramanis 
I tried over ten .dts files made from snippets of the files you 
recommended, as well as other ideas. I keep getting error messages similar 
to:

*panel panel.11: Failed to get pinctrl*
>


Then I tried *BB-BONE-LCD4-01.* It loaded no problem, and fb0 was present. 
The strange thing is:

cat /sys/devices/bone_capemgr.9/slots

It says the version is *00A0*, but that file is nowhere to be found. 
Loading 00A1 also fails. 


*lsinitramfs -l /boot/initrd.img-3.8.13-xenomai-r83 | grep 
> BB-BONE-LCD4-01-00A0.dtbo*

 ...returns nothing.

I tried compiling copies of each of the (4) historical versions also. They 
all failed. 

https://github.com/beagleboard/linux/commits/3.8/firmware/capes/BB-BONE-LCD4-01-00A0.dts

My best guess is that I'm using the wrong version dtc.

dtc --version

Is that old enough?

The dtc compiler version is:

DTC 1.4.0-gf345d9e4


I made a .dts file with fb section + corrected uart:

So first, make sure you are using the old dtc compiler, it should be
installed in /usr/local/bin/dtc

second, for your overlay, 3.8.x needs a fb section:

https://github.com/beagleboard/linux/blob/3.8/firmware/capes/BB-BONE-LCD7-01-00A3.dts#L272-L280

with 3.8.x the usart is off by one:
