LCD Expansion Port not working with Sabre Android BSP Demo images

btjosh — Thu, 19 May 2016 14:36:18 GMT

Hi Experts,

The iMX6 SoloX Sabre board LCD Expansion Port is not working with the default BSP images for Android.

Both MCIMX28LCD and MCIMXHDMICARD are not recognized when connected. I do not have the LVDS based LCD display, so I am unable to test if video is working using that either.

Can anyone comment how to configure the default Android Sabre BSP images to work with either of MCIMX28LCD or MCIMXHDMICARD?

I have tried many comments in the discussion forum here on configuring U-boot with specific bootargs, but nothing has worked.

Thanks in advance

refer to the android relese note, mx6sx supports lvds only, but for linux, as I known can support hdmi (sii902x), if you need to support hdmi you should refere to the yocto bsp driver.

Thanks, confirming the same. Neither the MCIMX28LCD or MCIMXHDMICARD worked with out-of-the-box Android images for the IMX6SX. Purchased the MCIMX-LVDS1 and this worked as expected.
