imx8QXP - MEK - LVDS - HDMI Display

Hi,

 

We are working on imx8QXP - MEK HW to realize automotive cluster under linux. As a first step we are using the prebuilt binary images(Linux Binary Demo Files – i.MX 8QXPlus MEK) from "https://www.nxp.com/pages/alpha-beta-bsps-for-microprocessors:IMXPRERELEASES". Though we could boot the HW with the prebuilt image, we are unable to bring the display UP. The LVDS0/DSI0 interface of imx8QQXP-MEK HW is connected to a HDMI display via IMX - LVDS - HDMI daughter card. With this HW setup, we are trying to run the display test script "autorun-fb.sh" that comes with the file system of prebuilt image. This script fails with the error

 

Setting FB to 24-bpp

"./autorun-fb.sh: line 35: echo: write error: Invalid argument"

"FAIL - Unable to set bpp"

"FAIL - Unable to set virtual size" & so on...

 

Any help to bring the Display UP in imx8QXP - MEK board is greatly appreciated.

Thanks,

Deepa
