Hi Team,
I have designed an board with iMX6ULL. The board is powered ON successfully and while booting, the below pint is displayed.
U-Boot 2016.03-nxp/imx_v2016.03_4.1.15_2.0.0_ga+ga57b13b (Nov 02 2020 - 12:48:26 +0530)
CPU: Freescale i.MX6ULL rev1.1 69 MHz (running at 396 MHz)
CPU: Industrial temperature grade (-40C to 105C) at 55C
Reset cause: POR
Board: i.MX6ULL iW-RAINBOW-G18M-SM
Boot Device: NAND
I2C: ready

### ERROR ### Please RESET the board ###
I have tried resetting the board multiple times and observed same print.
One of the GPIO (E5 pin of CPU - CSI_PIXCLK) we are using for enabling peripheral power control for the switch. By default the GPIO is externally pulled down.
When the external pulldown is removed for the same GPIO, the board is successfully booting.
Kindly let me know what is the reason for such error when the pin is pulled down.
Thanks and Regards,
Nibin
