I am testing the Beaglebone black C and LCD displayer 4DCAPE-70T that is
pruced by 4D-systems now. If ADconveter that is installed in the beaglebone
black C works, the touch panel that is provided in 4DCAPE-70T works very
slowly and sometimes CPU halts at all.
For example

Can anybody tell me if this patch has been implemented in 4.0.0-bone0?

Robert, could I connect a keyboard and monitor and see the boot messages on
the monitor, the same boot messages that would appear on the serial
console? I'm asking because I could connect a monitor today, but I'd have
to order a FTDI cable, which would take a few days to arrive.
Thanks,

The only difference is, I was able to capture more using debug console.

Hi Peter.
I replicate this as many times as I want.
I have got can0 interface and SIM908 connected to ttyO2 (GPS) and ttyO4
(GSM).
To achieve this all I need to do is:
Option 1:
run candump can0 in one session of putty
cat /dev/ttyO2 (gives GPS position) on second putty session
Wait a little
Great, thank you.
This means it is related to something else.

Is this one also applied to 4.0.0-bone0?

Pretty sure that just means that DT overlays are not in mainline for 4.x.
@Robert, does that mean the next kernel will have overlays in, or . . .?

On Windows puTTY is probably your best bet. I'd say that *everyone* who
uses COMx devices on windows use it, but I'd probably be wrong. There are
many apps out there. But puTTY and the paralax serial app are the two most
prominent on my mind.
