Hi Dave, your build output looks ok to me. The /lib/modules folder is created if the symbol "MODULES" is set in the Linux kernel configuration.
... if [ "$CONFIG_MODULES" = "y" ]; then \ [ -d /home/christian/uClinux-dist/romfs/lib/modules ] || mkdir -p /home/christian/uClinux-dist/romfs/lib/modules; \ ... Have you enabled the option "Enable loadable module support" in the Linux Kernel Configuration that sets this symbol?

Hi Dave, if you build the loadable module with the make process for the image the loadable modules should be in /lib/modules/<version>/kernel/... Regards, Christian Hi, I have successfully built a simple driver module configured for built in operation and it runs at startup - great so far. I then built it for loadable operation and it builds ok. I am left with a .ko file. When I download my new image to the target, I cannot see the ko file in order to load it. Do I have to download the module separately or should it be part of the image and visible somewhere? Is there anything else I need to do other than enabling loadable module support and selecting the loadable module <M> in the config? I'm running 2.6.30 btw.
