iMX6S Wandboard can not boot?

[toanjunifer]

Hi,
I'm Toan. I'm using iMX6S wandboard with Yocto OS(I get from wandboard download section). I have bought since last year. Recently, I have an issue. I can't boot it up. I don't know what did I do. Normally, at booting, LED2 in core board will light up. But bow It's not. And the serial output shows nothing.
This is normal state:

This is error state:

What should I do to fix this ?

Thank you so much,

Toan

Hello Dao,

     The evaluation board we released is MCIMX6DL-SabreSDB board,  it seems that your board is designed by 3rd party, we don't have corresponding design files, there is no way to help you analyze the problem.

     The better way is to contact your provide to get more help.

Have a nice day!
