IMX6 Purple pixels and purple contours (LDVS)

[denisvautour]

Hi

We are using an IMX6 dual with Linux BSP. After many hours of continously showing video (LVDS port 1368x768), we get odd purple contours around certain shapes.  Does anybody know what can be causing this undesireable effect?

Hi denis

one can look at solution and patch for pixelation issue

also one can check if this is caused by jitter: check lcd signals by

oscilloscope, use short cable and just for test increase

VDDSOC_CAP and add more capacitors on it.

Best regards

igor
