[Overlayfs for NanoPi M1]

Hi,

 

I test it on armbian Jessie fresh install on Nano pi M1 - http://www.armbian.com/donate/?f=Armbian_5.14_Nanopim1_Debian_jessie_3.4.112.7z

[Overlayfs for NanoPi M1]

Hi,

 

I tried the instruction provided on topic http://forum.armbian.com/index.php/topic/1526-armbian-in-read-only-mode/?hl=overlayfs#entry11877 but I received kernel panic and the system doesn't boot any more. I mount the SD card on my laptop, I comment the line overlayroot="tmpfs" in /etc/overlayroot.conf and the system boot again.

 

The package apt-get install overlayroot is not available.

In installed it manualy from http://packages.ubuntu.com/en/xenial/overlayroot

When I installed the package cryptsetup it return un error that cannot determine the root partition from /etc/fstab

 

Please be so kind and write step by step instructions howto make the root file system read-only.

Include also the final content of /etc/overlayroot.conf and /etc/fstab

 

Best regards,

Thank you borombo,

 

I configured alsa mixer and now I can play multiple mplayer audio instances.

 

Please be so kind and help me again:

I can't play video on hdmi because output is in text mode (I can see only few big square pixels). If I start X everything works fine, but I like to play a mp4 file without install X.

Thank you for your answer, now mplayer works fine.

 

I have another problem.

I wish to play 2 instances of mplayer or vlc or mpc ( a background music as first player)  and an announcement as second player.

 

The first player plays ok, but the second return:

 

[AO_ALSA] alsa-lib: pcm_hw.c:1557:(snd_pcm_hw_open) open '/dev/snd/pcmC0D0p' failed (-16): Device or resource busy

[AO_ALSA] Playback open error: Device or resource busy

Failed to initialize audio driver 'alsa'

Could not open/initialize audio device -> no sound.

Audio: no sound

 

please help
