i.MX6 kernel boot parameter "ldb=" still active?

All,

I remembered i.MX6 L3.0.35 supported dual LVDS display to set kernel parameter such as ldb=dul0.

Then I tried this for KK4.4.3 but some of them were ignored.

     c.f. u-boot=> setenv mmcargs .... ldb=dul0

           u-boot=> boot

The results were:
      ldb=dul1 OK                           #dual  (same output to 2 panels)
      ldb=sep  Fail(same as dul1)   #serarate
      ldb=spl1 Fail(same as dul1)   #split (2 ports for 1 panel)

Is this parameter still valid/alive?

Thanks.

Hello Thorus,

Did this work for you with previous versions of android?.

As far as I know, android cannot send separate video through 2 different channels, that is why only dul1 works


Have a great day,
Sergio
