Kernel Stops booting in Starting kernel ...

Contributor I

I am having Custom i.MX6ULL based board(NAND boot) which is currently having 4.1.15 Kernel . Now I am trying to port Latest NXP community BSP( ). This has following Items :

  1. Yocto Rocko 2.4
  2. Linux Kernel 4.9.88
  3. Uboot 2017.03

My plan is to retain older Uboot and just change Linux kernel and Rootfs. For this I ported My device tree(DTB) , defconfig and board file related to my board. But unfortunately Booting stops in  "Starting kernel ..."

Starting kernel ...

I have Few doubts here.  I am using older version of Uboot

  1. Whether using Older version of Uboot is OK?
  2. How can I debug more on "Starting kernel ..." .

Thanks in Advance.

Hi Keshava

>My plan is to retain older Uboot and just change Linux kernel and Rootfs.

this may be issue. Recommendation is to use nxp linux

freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel 

and corresponding with it imx_v2017.03_4.9.88_2.0.0_ga uboot

uboot-imx - i.MX U-Boot 

Note, community bsps are not supported by nxp, issue may be posted on

 meta-fsl-arm mailing list:
