Hello, here is my configuration:
Raspberry pi 3
Hifiberry DAC+ standard
16GB SD card
static LAN address
no WIFI (disabled completely)
running headless (no display, no keyboard, no VNC, no X11, etc)
– raspberry settings
– SD-Card Protection
I’m using it as an audio player only. LMS (Logitech Media Server) is installed on another computer on my network. I have no need or intention to install LMS on my Raspberry PI.
All works well, *until* I enable SD-Card Protection. After I click the REBOOT button on max2play, the PI goes offline, and won’t boot again. Or at least, I can’t access it over the network, so it’s functionally down.
While running, nmap gives this result:
PORT STATE SERVICE 22/tcp open ssh 53/tcp open domain 80/tcp open http 139/tcp open netbios-ssn 445/tcp open microsoft-ds 3389/tcp open ms-term-serv
After the reboot, nmap gives this result:
Note: Host seems down. If it is really up, but blocking our ping probes, try -PN Nmap done: 1 IP address (0 hosts up) scanned in 5.26 seconds
I have a static IP address assigned to the PI, and am not using DHCP or wireless at all.
I would like to enable write protection, as the planned usage for the device is in a location where power is not always reliable. However, at the moment, it appears that write protection does not work at all for me.6. December 2017 at 17:09 #32808
I have a similar problem here – wifi and bluetooth disabled and the RPi is not present in LAN after booting. Sometimes powering off and on several times helps…
What i figured out and seems to be a solution for the moment in my situation:
Disabling the fix ip adress within the RPi’s webinterface and forcing the router to assign always the same ip adress to the RPi while handling DHCP. I use a fritzbox router and changing this setting is very easy.

I have 3 RPI’s with Max2Play running here – all of them have the sd card protection activated. Two of them don’t have any problem after rebooting and are still reachable in the network (both with jivelite running, TFT attached and with fixed ip adress in the network tab), but the one without jivelite and TFT has the problem with the ip adress as described.

I set up a DHCP server on my local network, and disabled the fixed LAN address on my rasp pi.
After installing and enabling SD-Card Write Protection, the rasp pi is able to reboot and functions normally.
This is an acceptable solution for now.
The original issue is still open / unsolved: fixed LAN address + Write Protection = unbootable rasp pi.
