I once successfully built ZImage、Rootfs、.imx .dtb file and flash them into emmc, and everything was ok(one month ago). But this time, i change the kernel and recompile it , build is ok, no error. But this time after i flash them into emmc, i can't find unit test package in the root direction, and ssh also disappear(i use putty to ssh the board) , and i tftp mxc_vpu_test.out file to the board and execute it, it say no libvpu.so.4 , i think it not vpu lib. But i follow the steps what i did one month age, and didn't change anything. i use mfgtool to flash it , even i use the old files(what i built one month ago), it is still same.
i delete the charge-led driver in the new one , so i can confirm i flash the old one cause charge-led driver still in the /sys/class/leds/ dir. Can anyone tell me, what may happened and how to solve it.
I use Imx6QSABRESD BOARD. kernel version: core-image-base linux： YOCTO
THANK YOU！
