Are you using MFGtool?
What is the different between your board and evk board?
Have you modify the u-boot and kernel base on the different on your board?
If you are using mfgtool, have you generate a new firmware for your board?
Is there a debug console output from your board? any log message and where is it stopped?
Hello, thanks for your reply.
Yes I use the MFGtool to download the programs, but my board is a little different from the evk board.
I have not modify the U-boot and kernel, and haven't generate a new firmware for the board.
I am now looking for the reason from the hardware circuit.
