[baijinlong]

hi,

      we have a custom board same as iMX6ULLevk,Then by using Mfgtools flashed compiled images to NAND successfully.

      But at the booting time it is getting stop at "cpu cpu0: dev_pm_opp_get_opp_count: device OPP not found (-19)" without any errors.

MFGTOOL failed after booting the kernel：

                     

  we attached custom board logs.

The problem has been found. This problem is a problem with the kernel image. Recompile the firmware/zImage on it. I estimate that the kernel version is inconsistent. The corresponding solutions are as follows:
Compile zImage of MFGTOOL tool configuration, ie imx_v7_mfg_defconfig configuration, generate zImage into
In the mfgtools/Profiles/Linux/OS Firmware/firmware/ directory, you can write it; in addition, you must correct the DDR data and DDR stress test.
