FLTK is a cross platform GUI library.

But I changed my decision. I want use Qt. Now I'm working on buildroot. Did 
you use buildroot in your project?

 For a 5 second bootup time, your going to have to do a lot of work..

 I'd first start with buildroot and make sure to use u-boot in falcon 
 mode..

RT linux is just scheduler difference? more frequent switching?

if this is what you mean, you can still optimize to 5 sec.

to date, we don't have a PocketBeagle overlay for usb configuration of
the second port..

Patches welcome ;)

PS, sometimes this issue just bad wiring, double check your
connections and make sure you have real 5v of power.

[beagleboard] Ubuntu Device Tree Issue on PocketBeagle

2019-01-06 Thread rosehulmanuniversity 
Hi,

I am working on the PocketBeagle platform and using the USB breakout pins 
to interface with devices. I had successful communication with USB devices 
with the debian image for the PocketBeagle. I tried running the Ubuntu 
image and ran into a problem with the device tree configuration.

I tried to change the uEnv.txt by adding this line:
dtb=am335x-pocketbeagle.dtb

However, it resulted in the same error.

When I see the following error, I feel like the current configuration isn't 
setting the USB as ground (host).

[beagleboard] Ubuntu Device Tree Issue on PocketBeagle

2019-01-06 Thread rosehulmanuniversity 
Hi,

I am working on the PocketBeagle platform and using the USB breakout pins 
to interface with devices. I had successful communication with USB devices 
with the debian image for the PocketBeagle. I tried running the Ubuntu 
image and ran into a problem with the device tree configuration.

I tried to change the uEnv.txt by adding this line:
dtb=am335x-pocketbeagle.dtb

However, it resulted in the same error.

When I see the following error, I feel like the current configuration isn't 
setting the USB as ground (host).

It's probably an issue with the boot loader.  Hook up a serial console
to see what's going on.  Pause U-Boot when prompted (hit a key) and
dump the environment (printenv).

The kernel version shouldn't matter, but the BBB boot loaders have at
various times been setup to look for files like uEnv.txt in various
places.  I suspect the U-Boot installed on the uSD is seeing something
on the programmed eMMC that it doesn't like and/or breaks the boot
sequence.
