Other Parts Discussed in Thread: TDA2PXEVM
Hi, we are seen strange behavior on TDA2P display subsystem.
Looks like some uninitialized memory at the bottom of frame. Sometimes it has some "stripe" pattern, sometimes not, but always present.
Our setup to reproduce such behavior:
- TDA2PXEVM board with Fusion Application Board attached
- D3CM-IMX390 connected to port0 on Fusion Board
- HDMI port of TDA2PXEVM (not Fusion Board) connected to HDMI input on PC display (DELL/ThinkVision/any other)
- VisionSDK 3.07.01 (or 3.08, same behavior)
- VisionSDK config: tda2px_evm_linux_all
- ISS usecase: 1CH ISS Capture + ISP + DISPLAY
Also, we saw same behavior on our custom PCB with TDA2P and custom LCD panel connected to parallel interface (DPI). LCD panels have different resolution than 1080p used for HDMI, but this pixel line still there.
Such behavior seen on displays no matter what number of camera streams we are showing in mosaic on display.
This pixel line is always on bottom of whole frame shows on display. That why we think the problem is near the DSS.
Maybe somebody can help us with debugging this case?
