TDA2HG: vblank wait timed out

Part Number: TDA2HG

Hi,

My software version: visionSDK3.08.

When I make a boot sd card, the drm crash log appears when it first starts.

In order to reproduce this phenomenon, I put avm_qt_app in front of apps.out to start, and then this kind of crash almost became a phenomenon(9/10) .

Is the control screen too early to cause the abnormal phenomenon?

The crash log is as follows:
