Hi,

we have got customized board based on IMX6 Dual processor. Now when we have deployed linux image to the SD card and powering on the board, then nothing is happening ( no display is shown) ( monitor is connected to board through HDMI)

 

When we keep the same sd card to another evaluation board, then it is booting. Now to trace out the problem:

 

how i can confirm the processor trying to read/boot from the sd card, which happening but there is problem with the HDMI.

 

or

 

SD card reading is not happening.

 

how trace down where the problem is . when i connect the board to my Ubuntu host system through USB-OTG and run the command $lsusb

 

iam getting following message:
