Yocto HDMI dispaly custom hardware issue

[saurabh206]

Hi,

We are having custom hardware, We found one strange issue.

Yocto core-image-minimal build work perfectly with HDMI display, LVDS display is also works fine.

While fsl-image-fb build works find with LVDS display but With HDMI display set system hangs.

Any possible issue why hdmi display is not working with fsl-image-fb?

At which point does the system hangs? Would you please provide more details on the error and if possible an error log? Perhaps the boot arguments are not correct for HDMI output, how are you changing the active framebuffer from the LVDS to tge HDMI?
