This example is using my setup, which happens to be a RNDU6000 which I upgraded from 4.x to be able to run 6.x OS (http://www.readynas.com/forum/viewtopic.php?f=35&t=70323)
I'm creating this because the info was spread across multiple threads here, and was unclear in some spots, with conflicting info.
First, grab the source for the version you have installed. 6.1.6 in my case: http://www.readynas.com/download/GPL/readynasos/ReadyNASOS_V6.1.6_WW_src.zip Other versions: http://www.readynas.com/download/GPL/index.php?dir=readynasos Older versions: http://www.readynas.com/download/GPL/index.php Alternative URL: http://kb.netgear.com/app/answers/detail/a_id/20684/
sudo su cd mkdir temp cd temp wget http://www.readynas.com/download/GPL/readynasos/ReadyNASOS_V6.1.6_WW_src.zip unzip ReadyNASOS_V6.1.6_WW_src.zip
This will extract a lot of stuff, but one directory of value will be the 'linux-3.0.101' or similar dir! Where we can find the previous config file, and work from there. THIS IS EXTREMELY IMPORTANT TO START FROM:
You will need to compile the full kernel so any modules have proper references
You need a custom kernel name reference which is present in this config
cd ~root/temp/linux-3.0.101 cp defconfig.x86_64 .config
You'll need some additional packages to be able to compile the kernel:
These should be available, but if not, check /etc/apt/sources.list for these values:
deb http://apt.readynas.com/packages/readynasos 6.1.6 updates apps main deb http://mirrors.kernel.org/debian wheezy main deb http://ftp.us.debian.org/debian wheezy main non-free
and then update:
apt-get update
and try again.
You now should be able to configure your kernel:
make menuconfig
Select whatever modules you want/need.
Then compile (YOU CANNOT ONLY COMPILE THE MODULES, YOU MUST RUN THIS FULL KERNEL COMPILE😞
make ARCH=x86_64 make modules_install ARCH=x86_64
You now should have available and installed into /lib/modules/3.0.101.RNx86_64.2.1/ your new modules. modprobe and enjoy! (you may need to run depmod -a to have the new modules found by modprobe.

Your modules will be available in /tmp/build/modules. For simple modules such as USB serial and such you should be OK with just copying the modules over, however more advanced things (iptables NAT for instance) require replacing the kernel as well.
I still running in to some errors when i'm trying to compile the desired modules... I have a ReadyNas RN102, with firmware 6.1.8.
I want to compile the usb serial driver modules: - PL2023 - Generic Serial
I did al the above instructions, accept: - I copied this file /linux-3.0.101-0.15/arch/arm/configs/armada370_nas_defconfig to /linux-3.0.101-0.15/.config - Then I ran menuconfig, and enabled the modules. - Followed by make arch=arm
Then I receive the following error: make: arm-mv7-linux-gnueabi-gcc: Command not found
This must have something to do with cross-compiling. But as far as I know, I don't want to crosscompile, because i'm compiling on the machine.
I tried to edit te .config file. Commented the line: #CONFIG_CROSS_COMPILE="arm-mv7-linux-gnueabi-" Then its starts compile, but in the end I see a lot of errors and can't find my modules...
I'm looking at how to compile kernel modules following your instructions, however I run into a bunch of issues:
- if using local compilation on the NAS itself, the make command exits as it cannot find the cross compile toolchain (which is odd, since I'm using local compile...)
- when trying to use the ReadyNAS VM you reference:
- basic apt-get commands fail, trying to resolve a link which apparently does not exist anymore (even a simple apt-get install man-db fails). Likewise, apt-get update fails on several IP (which however do resolve)
- the link to the cross compiler you indicate below does not exist anymore...
