Hi,

    I was successfull boot kernel by uboot2016 and boot uboot by spl on the IMX6DQ . But i can't boot kernel directy by spl.

The log is stopped at: Uncompressing Linux... done, booting the kernel. 

    I have set up boot parameters and machine code in SPL.

    Can you give me some suggestions?

Thanks.

Hi, 

    The SPL can start uboot ,then starts kernel is successful. The DDR parameters used by SPL and UBOOT should be the same set. 

If DDR parameter is a problem, uboot should start kernel failure. Or is there any other reason? (I was use uboot 2016 boot  kernel 3.0.35)

Thanks..
