Re: Raspbian Stretch

You *should* however make the kunbus sources a higher priority than the raspbian sources. Otherwise there might be the risk of a future upgrade reeling in a kernel coming from raspbian instead of kunbus which ships a patched version. Our kernel package has epoch 9 whereas Raspbian has epoch 1 (firs...

Re: Revolution Pi Core 3 - zu heiß

Nach einer Hand voll installierter Updates blieb er jetzt mit einem Thermometer-Symbol in der rechten oberen Ecke auf dem Monitor stehen (Raumtemperatur ~23 °C) :( Ist die heißeste Lösung die CPU über die config.txt herunterzutakten? Ein halb gefülltes Thermometer-Symbol signalisiert, dass der Takt...

Re: RevPiModIO - Python3 Direktzugriff auf IOs

Danke für den Hinweis Sven, ich habe python3-revpimodio 0.10.0-1 sowie revpipyload 0.3.0-1 soeben in das apt Repository aufgenommen. Das muss immer durch uns manuell erfolgen, wegen der kryptographischen Signierung der Paketlisten. Die Pakete befinden sich im "contrib" Bereich unseres apt ...

Re: Using Pixel

PIXEL is a graphical desktop which is included in our jessie image (released yesterday). The Revolution Pi boots to the command line by default because the graphical desktop consumes a significant amount of memory and noticeably prolongs the boot time. You can manually start the desktop with "s...

Re: Kernel module + Core 3 questions

I did have a look at this during the weekend and I would first like to understand a bit more what kind of concurrency model you're going for here before actually writing some code - the things is: my questions about this would be far more technical than the ones I've already asked here - so should ...

Re: [Jessie] Separating policy from binaries

Ok great. May I ask, how were you able to perform a dist-upgrade despite the puny 4 GB eMMC? I'd expect /var/cache/apt/archives to overflow, did you mount that on a USB stick? Initially we'll only post a tutorial to upgrade by flashing a new image, but we intend to follow up with another tutorial to...

Re: [Jessie] Separating policy from binaries

Hi Christian, no reason at all to apologize for providing valuable feedback. :) disallow any user to start an interactive shell except pi and automatically calls revpi-factory-reset unless a dotfile in pi's home directory exists Okay the former is actually a bug, other users except for the pre-confi...

Re: Kernel module + Core 3 questions

Thanks cseiler for opening this thread, I'm delighted to get some hardcore questions here. The kernel module parses the configuration JSON file from the filesystem directly - and uses the set_fs(DS_KERNEL) trick to use the VFS API to read the file. Wouldn't it be better for the kernel module to prov...

Re: Is the OS soft or hard float?

Just to confirm Volker's statement, yes the OS shipping on the RevPi Core (which is essentially a stock Raspbian + kernel with RT patches + a few userland additions) does make use of the ARM CPU's hard float capability. In case you're interested in the gory details, the ARM CPU on the Compute Module...

Re: Echo :Write Error: Connection Refused

Hi gopal30, Unlike the Raspberry Pi 3 and Raspberry Pi Zero W, the Compute Module doesn't have on-board Bluetooth. So the first question is, how did you make your RevPi Bluetooth-capable, perhaps with a USB adapter? If so, which one? (So that I can check if a driver was actually shipped with our whe...
