Cannot change device tree in iMX6q

Question asked by Zhongjian sun on Mar 7, 2018

hi,

     I have a serious question about imx6q device tree.

     When I change dts file and compile it to dtb file, using 'scp' to copy dtb file to imx6:/run/media/mmcblk3p1, and I copy the file from imx6 to PC to confirm it's the right file. But when I reboot imx6, I found the dtb file is the same as old dtb file. Even I rewrote the file system with the new dtb file, the dtb file in imx6 still not change.

     It botherd me for days. Is the EMMC broken? Read Only or somthing?
