I recently buy a new MCIMX6ULL-EVK board. There seems to be 2 problems with the board.

1. After powering on or resetting the board, it sometimes cannot start sucessfully.

The console messages are shown as follows.

Power on

U-Boot 2016.03-imx_v2016.03_4.1.15_2.0.0_ga+g0ec2a01 (Nov 05 2016 - 01:13:31 -0500)

CPU: Freescale i.MX6ULL rev1.0 at 396MHz
CPU: Commercial temperature grade (0C to 95C) at 47C
Reset cause: POR
Board: MX6ULL 14x14 EVK
I2C: ready
DRAM: 512 MiB

No following messages anymore, the board seems to be not working, and then I Reset the board by pressing the reset button.

Still not boot up.

After another reset, it finally boots up the u-boot.

(BTW, I start the board without connecting LCD screen. Does it matter?)

I use the original SD card (no content changes) shipped with the board. It is brand new product and I buy it from certified distributor. Is there something wrong with the HW or SW of the board? Need help.
