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 , 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
