SK-AM62-LP: DRM / LVDS Display Permission Errors on AM62PX with SK-LCD1

Part Number: SK-AM62-LP
Other Parts Discussed in Thread: SK-LCD1

Tool/software:

Hi,

I am using an AM62PX processor connected to the SK-LCD1 display (datasheet) and running the prebuilt demo applications on Processor SDK Linux.

When I launch the demo (ti-apps-launcher or directly the QML file auto_cluster.qml), I see the following errors:

root@am62pxx-evm:/usr/bin# qml /opt/ti-demo/auto_cluster.qml
Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.
Failed to move cursor on screen LVDS1: -13
Failed to move cursor on screen LVDS1: -13
Could not set DRM mode for screen LVDS1 (Permission denied)
Could not queue DRM page flip on screen LVDS1 (Permission denied)

I followed the guide at How to enable Microtips LVDS Panel to configure the display, but the issue persists.

Are there recommended steps to successfully run demos with LVDS1 on AM62PX?
