SK-AM62P-LP: How To Remove Linux Drivers

Tool/software:

Hi,

I am using the SK-AM62P-LP board and need to remove some Linux drivers, but I keep encountering errors. I tried the following commands:

root@am62pxx-evm:~# sudo rmmod ecc rmmod

ERROR: Module ecc is in use by: ecdh_generic

root@am62pxx-evm:~# sudo rmmod ecdh_generic rmmod: ERROR

Module ecdh_generic is in use by: bluetooth

root@am62pxx-evm:~# sudo rmmod bluetooth rmmod

ERROR: Module bluetooth is in use

I also tried stopping the Bluetooth daemon:

root@am62pxx-evm:~# sudo systemctl stop bluetoothd

Failed to stop bluetoothd.service: Unit bluetoothd.service not loaded.

How can I fix these errors and successfully remove the drivers?

Regards,

Veerapandiyan V.

Hi,

Why do you want to remove these kernel modules? Do you not need them at all or just try to remove and reload to solve some runtime problems?

Hi Bin,

I'm trying to remove these kernel modules to reduce boot time for an automotive project.

The best way is to disable the unwanted modules in kernel menuconfig, so that they won't be installed in your root filesystem.

Hi Bin,

Could you please share any user documentation or guidelines on how to disable unwanted modules using kernel Menuconfig?

Hi,

This is a generic Linux kernel question, you should be able to find plenty of information on Internet. The link below to the Processor SDK Documentation also shows how to use kernel menuconfig. You can disable kernel modules once you are in the menuconfig interface.
