Re: Piserver and Eclipse

Doesn't sound like a Piserver specific issue to me. There are no Eclipse packages for Debian Buster. (Not for Intel computers either) Avoid Eclipse if you can. If not, you can try using an older Raspbian Stretch image as operating system. http://downloads.raspberrypi.org/raspbian/archive/2019-04-09-...

Re: RPI and Buildroot - QT APP on startup and Starting Network

Do device management through udev and it will load the modules asynchronously for you (in the background and no need to modprobe anything manually).
Do may need to comment out "udevadm settle" in the init script so it does not wait before continuing.

If you are not connected to the Internet for time synchronization, that is best fixed with hardware clock.

Re: PiServer and Lego NXT lejos ant compile error

Your screenshot also shows it is missing jar. You did install "Raspbian Full " as operating system in Piserver? (As "Raspbian" without the "full" no longer comes with the Java stuff pre-installed) As far as it not finding jni.h, you may need to help it bit. Enter "leafpad build.xml" Change: <conditi...

Re: Updating piServer for RPi 4 network boot capacity

Piserver does detect that the Pi 4 is network booting?
As in it does appear in the "add clients" window?

Also make sure you have recent firmware files on the operating system you are trying to boot (may need to go to tab "software" -> start "shell" -> and run rpi-update)

If in doubt, use WWNs...
The Linux kernel by itself does not understand those.
So that only makes sense if the Linux distribution you are using has an initramfs with helper code to resolve those and mount the root file system. Raspbian by default does not.

Well that worked. Adding the vcdbg packag lets me import the picamera module without errors. Doubt you actually need vcdbg. The reason it works if you enable it, is because vcdbg has a dependency on rpi-userland, which is the package you need instead. While I had that package enabled, I didn't have...

Double check you have dhcp-reply-delay=2 in your dnsmasq.conf NetBoot is not one of Pi3B’s forte.

Managed to reproduce it on a 3B+, reported it to dhcp's author, and he issued a fix.

If you want the updated version, you will need to compile it from source for now:

Code: Select all

I followed official RPi kernel building documentation for local build, just changing to KERNEL=kernel8 but it broke the Raspbian.
You will need a real 64-bit operating system (e.g. OpenSuse), and not Raspbian, if you want to do a native build.

Today on my Pi 3B it's not giving either IPv4 nor IPv6 until a long time later, then it gets the IPv4 local link address. Though it did get the initial IPv6 as you noted. That IPv4 takes ages is normal. IPv4 link local is only given if there is no response to DHCP, so DHCP has to timeout first, and...

The difference on the 1B is it re-adds the address after the second IAID -
See it also goes up, down and up for me, but does add the IPv6 for me, even on Pi 4.

Perhaps a timing specific bug in dhcpcd then.
Hard to report to the author though, if it is not so reproducible.
