Hi jie

seems this message is from ..drivers/input/touchscreen/max11801_ts.c

Is this chip used in custom board, in general one can debug it using
AN4553 Using Open Source Debugging Tools for Linux on i.MX Processors

Best regards

Hi, igorpadykov

I am glad to see your repay, The chip max11801 is used for touch panel controller in my custom board. The operation to touch panel is normal. I want to watch the kernel information using the command dmesg. but now It fails. The document will be useful when I debug. Now I just need to watch , not to debug.

Best regards
