There are no other information to be listed, just the information above . My core board is imx6q . I need you help, thanks!
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

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
Allen
