hi Rita Wang!
After I received the development board, the power on the system starts up, and the system stops running in the starting kernel...;Later, I downloaded linux-imx-rel_imx_4.1.15_2.0.0_ga.tar source code, compiled, generated zImage and DTB, copied to micro SD card, and then started is the log as described above:
