Subject: [Buildroot] problem with building kernel modules.
Date: Fri, 15 Nov 2013 21:24:49 +0100 [thread overview]
Message-ID: <3FF194268D984DEF96AF81E6681E03E9@JohanW7> (raw)
Hi
I have a kernel module that I build and install trough the build system.
This works fine, the module gets build, installed and depmod is run for it.
The problem occurs if I change the kernel config, the kernel build system
removes all target/lib/modules/2.6.36.../kernel/* files , including my built modules.
As a result, my modules are missing.
How can this be solved ?
