Kernel panic - not syncing: No init found. Try passing init=

[lilleli]

hello community,

    I am port fsl_yocto-L4.1.15_2.0.0-ga bsp in the imx6ull hardware platform,kernel ,device tree, file system ,bootload

rebuild is succes,I write a simle test program,for example test.sh, I want push in rootfs_nogpu.tar.bz2,Do the following,

1,tar jxvf rootfs_nogpu.tar.bz2, -C /mydir

2,cp test.sh /mydir/etc/

3,tar jcvf rootfs_nogpu.tar.bz2

Finally download kernel,rootfs_nogpu.tar.bz2,uboot,by mfgtools ,is no problem,

and power on evbboard boot from sd ,The following error occurred.

Hi lille

"try passing init= option to kernel" may be due to kernel versions differencies, as

from log: "Linux version 4.9.11-1.0.0", while "fsl_yocto-L4.1.15_2.0.0-ga bsp" is mentioned

on post. Please try to rebuild image from scratch using one kernel version.

Best regards
igor
