Kernel headers for ReadyNAS OS 6.4 RN104
Good morning,
Apologies if this has been posted twice, I received an error when posting, and yet I can't seem to find it
I am attempting to build driver modules for DVB-T USB devices, using this link:
http://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers
To do so I need to install the kernel headers. I used the traditionnal Debian command: apt-get install linux-headers-$(uname -r)
which on 6.4 will attempt to install linux-headers-4.1.7.armada.1
Unfortunately it fails (no package name found)
I found here a link to download what I assume is the full kernel source:
http://kb.netgear.com/app/answers/detail/a_id/2649/~/gpl-open-source-code-for-programmers
I entered the linux kernel directory for armada, and ran the make headers_install command, which seems to complete fine
However, it does not seem to create the /lib/modules/4.1.7.armada.1/build folder, with the required files for DVB modules compilation to succeed.
So am I missing something ?
Ideally, it would be better if I could find directly the kernel headers
Alternatively I can try to compile the kernel directly with DVB support, but that's a little bit extreme...
Thanks and regards
I cannot answer your question about the kernel headers, but I think you have to recompile the kernel anyway as the Netgear kernel does not support DVB (at least until 6.3.5).
Also, I think you'll have to use the Netgear variant of the kernel source (copy the correct Netgear kernel config), not the Debian variant (because of kernel symbols, as I understand, but maybe that changed in 6.4.0 too).
I made a little recepe here for using HDHomerun (last post, ): https://community.netgear.com/t5/Using-your-ReadyNAS/Q-compiling-kernel-modules-on-OS6-dvb-hdhomerun/m-p/867251
This is confirmed to work on 6.3.3 and on 6.3.5.
I've read rumours that the boot code/process changed in 6.4.0 so I don't know whether the process to replace the kernel is still the same. And I have no intention to downgrade from 6.3.5 to 6.4.0.
Be sure to read and understand the warnings in the post: if it goes wrong, your NAS probably will not boot again, ever.

Just wanted to emphazise: the link in the precious post concerns a x86 system. For other systems, you probably need a Netgear kernel config file from a different arch.
Many thanks for these details
I find it quite amazing that Netgear did not built in DVB support in the kernel. Synology has it as far as I can tell (well at least compiling and installing tvheadend on a synology is a no brainer).
What I find also surprising is that DVBLogic claims for support of Netgear RN10x, with various USB sticks. And I would have assumed this would require DVB support in the kernel... Now that might be the reason why it does not work in the first place though :-)
That said, is there a recovery procedure in case the NAS is bricked ? If not, the risk is kind of high so I'll probably simply setup a Raspberry Pi as a TVHeadend (among other things) server. Granted it's not as integrated, and it's kind of a shame, but at least there is a huge community support, and it works out of the box
