Re: PiServer and Arduino

That does seem to be an issue with how you are doing the install or what you have as it works when installed under Raspbian as the "pi" user. Well, Piserver is a multi-user system for classrooms. So the user that will eventually run the application will be "name-of-student-that-logged-in", rather t...

Re: PiServer and Arduino

Judging by those messages, that install script is only written to install Arduino for just the current user (which happens to be root, when running the script through the Piserver chroot shell), instead of for all users on the system. Suggest you ask the Arduino guys why they do not offer scripts/in...

Re: Piserver DHCP Proxy - Clients do not boot

Can you tell OPSI to stop sending PXE boot options to Pi clients?

Code: Select all

Think it seems to confuse the bootcode into thinking it should get its stuff there:

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.

Your screenshot also shows it is missing jar. You did install "Raspbian Full " as operating system in Piserver?

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)

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.

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