Error! Your kernel headers for kernel 4.4.166-rockchip64 cannot be found.
Please install the linux-headers-4.4.166-rockchip64 package,
or use the --kernelsourcedir option to tell DKMS where it's located

Then when searching in aptitude for kernel-headers-4.4.166 then they are not available.    It is also impossible to compile because of the missing kernels headers. 

 

Install your kernel headers.

 

run armbian-config

Software/Headers

 

 

 

It is not so simple.   It seems to me that the kernel headers and kernel source are not available for kernel 4.4.166.

I just tried to install full source.   FAIL.  I got version 4.4.156 as well.

Solved it.

 

Somehow the builds got messed up for rk3399.     What I did to resolve it was in Armbian-Config I switched to nightly builds.  When I did, the correct kernel headers were installed.

Thank you for that, will try that out.    It seems to be okay both on firefly rk3399 and rockpro64.   

Ok, this is getting somewhere.

But there is no display connection.   So just connecting from firefly rk3399 to rockpro64 through minicom /dev/ttsyUSB0 and serial debug device, and ssh and trying to figure out why there is no display connection through hdmi with kernel 4.18.0.    Do you have any ideas?   

 

This is what is in /etc/X11/xorg.conf.d/01-armbian-defaults.conf

Did armbian-config through ssh and did system and nightly development build.  Now the display is back with kernel 4.19.0 .

Now when development kernel 4.19.0-rk3399 is running on both firefly rk3399 and rockpro64, On the first day I have notices 3 issues:  #1. Serial debugging through minicom is not possible, there is no /dev/ttyUSB0 (ls /dev/ttyUSB*).  tail -f /var/log/syslog

failed to execute '/lib/udev/mtp-probe' 'mtp-probe /sys/devices/platform/fe3c0000.usb/usb2/2-1/2-1.1 2 6': No such file or directory

  #2. It is not possible to install rtl8812au driver for my usb wifi dongle on rockpro64.    But this is a work in progress.

  #3. Bluetooth missing.  "This probably means that there were no Bluetooth adapters detected or Bluetooth daemon was not started.

Being a stubborn person, I am still trying to get a rtl8811cu for usb wifi dongle vendor 0bda and product c811 up and running.   The main hurdle have been a this error messages when doing make scripts from /usr/src/linux-headers-4.4.166-rockchip64/
