Hi experts,

 

I have a i.MX6 boot-up issue for Dual-lite CPU.

 

With the same PCB layout, I use four different CPUs.

 

1. Quad-Core Automotive (MCIMX6Q6AVT10AC)

2. Quad-Core Extend Commercial (MCIMX6Q5EYM10AC)

3. Dual-Core Automotive (MCIMX6D6AVT10AC)

4. Dual-Lite-Core Extend Commercial (MCIMX6U5EVM10AB)

 

And the power strap are followed AN4397 Hardware Design guide.

 

Now item 1~3 can boot up successfully, but item 4 (Dual-lite CPU) will boot up randomly.

I have use DDR3 calibration tool to get the ddr parameters and put into u-boot image.

But the issue still appear, the system will hang on "Hit any key to stop autoboot: 0" (please see the attached picture).

 

Does anybody has the similiar issue? Please give me some directions to solve this issue.

 

Thanks for your comments.
