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.
