I am trying to connect an SATA -> USB DVD-R drive to OPi3, but it fails, K3b complains about "no drive".

Here is syslog:

there is NO /dev/sr0 after plugging drive. At the same time SATA->USB HDD works w/o problem.

What am I missing? What should I do?

I want to record my motion recordings w/o need to transfer them to laptop.

armbianmonitor -u

root@orangepi3:/var/motion# armbianmonitor -u

Here it is. Don't know why there is an error.

If some feature is missing from the kernel but its possible to add it? Build the kernel with that feature and send a changed config upstream that it will not be gone by update.

 

https://github.com/armbian/build/blob/master/config/kernel/linux-sunxi64-current.config#L6518-L6525

I have no idea what else is needed to fire up CDROM. It has been 10y+ since I used it last time

Ok, here it is: "# CONFIG_BLK_DEV_SR is not set"

Not even =M (module)...

 

So I'll try to build my own kernel.

It is not that hard since the script will do most of the work for you.

The config You provided is for building whole Armbian? I need the one for kernel only (I have already kernel sources as I needed to compile "tmon" from there).

Just to put it in kernel source root, "make menuconfig" to change optical drives on, and "make; make install", - how do I update initrd?)

If you refuse using the build script to create a kernel package for your board (yes, it is possible to build the package only and not a whole image) then you are on your own.

Ok, if it is possible to build only kernel (I hope it will not download anything else...) thats GREAT, and I will try :) THX.

Well it will install some tools and of course will download the toolchain to make cross-compile possible. So first startup will take a while.

I have already toolchain on OPi3 + kernel source, can I use native compile?

You can try but it is not supported so you are on your own then.

Ooops, You were right:

[ o.k. ] Preparing [ host ]

Problem is that I have only 32bit Linux on x86, and 64bit Armbian....
