Hi, I have a Freescale SabreSD board with an i.MX6 quad-core processor. I'm using u-boot-2009.08 (released with Freescale's LTIB)
This list is about the official U-boot project, not the 2009.08 port from FSL.
I would like to enable both LVDS channels.
In mainline U-boot there is support for one LVDS panel in mx6qsabrelite board.
You can use it as reference and add LVDS panel support in mx6qsabresd.
Please send us the patches.
In the "lcd_enable" func (file: / board/freescale/mx6q_sabresd/mx6q_sabresd.c) I properly changed some registers following the advice of Freescale but I could not enable the second channel: https://community.freescale.com/docs/DOC-93617 Furthermore, the "ipuv3_fb_init" func is used to initialize a single Display Interface. Can you give me some advice to enable both channels?
What is exactly your use case? Do you really need dual display support in U-boot?
Can't you just boot fast and use the dual display support that kernel already provides?
