[vivektol]

Hi,

       We have custom board  based on freescle / NXP imx6dl sabresd board.

Our console UART Pins are differet  SD3_DAT7__UART1_TX

                                              SD3_DAT6__UART1_RX

and we have 2GB DDR3 RAM.

We have configure DDR RAM in uboot and console UART pins in uboot-imx and  kernel-imx.

When we are booting the android oreo images on our custom board we are getting kernel panic error.

Please guide us where is problem.

Logs of android booting on our custom board is attached.

With Regards,

VIVEK TOL

Hi VIVEK

kernel panic usually caused by ddr errors, one can try to run ddr test

i.MX6/7 DDR Stress Test Tool V2.80 

and rebuild image with new calibration coefficients found from ddr test,

modify uboot/../mx6sabresd/mx6dlsabresd.cfg

For flashing images recommended to use mfg tools from

Dear igor,

                 Thanks for your reply.

Now my kernel is booting properly and I am getting command prompt.

I am facing one issue that I am not getting uboot command prompt. I am not getting a message "Hit any key to stop autoboot" . Directly kernel is starting.

I want to change boot arguments for my  HDMI display. Please give some suggestions to solve this problem ?
