Hi zhang

to avoid this message one can try to rebuild all image with custom

application from scratch. Also one can try with new kernels from nxp repository

linux-imx - i.MX Linux kernel

Hi igorpadykov
    There's a bunch of machines.Using the same kernel, there are two machines in the thermostat for testing. One will happen every 24 hours or so, and the other has no abnormality. How to eliminate hardware problems?

Hi zhang

for every machine own image should be created, not recommended to use same binaries.
