The board is designed by our customer and the reference schematics is SPF-27516_C3 (Sabre_SDB board).

 

They download the images to eMMC on board. But they can not boot from eMMC. And they check the input power and OSC signal is normal.

But they can not find the eMMC's clk signal and other putout clk.

 

I don't know how to check the root cause. Could you give me some advise?
