Error in uninstalling FEC driver on kernel 5.10

jerry2004 — Sun, 08 Oct 2023 08:15:47 GMT

platform ： I.MX6

kernel： 5.10

We have compiled the FEC driver configuration into a ko module, and everything is normal when loading insmod. However, in the rmmod driver module, the following error will be reported. What is this error （rmmod:ERROR:Module FEC is builtin）and how to solve it? Thank you

Hi @jerry2004

It seems that the fec is already a builtin kernel driver. what have you modified?

You can do dmesg to check and zcat /proc/config.gz. also try to add print in remove of your driver.

Best regards
