Portsdown 5 Installation

Post by NJ6E » Wed Oct 22, 2025 8:52 pm

Hello,

I have been attempting to install Portsdown 5 from https://github.com/davecrump/portsdown5 and have run into a problem when Stage 2 installation begins. My setup is a Raspberry Pi 5 4GB with the DSI 7" touchscreen attached. The installation proceeds as expected until the end of Stage 1, when the installer reboots to begin Stage 2 installation. At that point, reboot begins, the screen backlight comes on, and then all apparent installation activity stops. There is no text on the screen and no LEDs on the Pi 5 flash to indicate activity. I have left it in this state for several hours, with no apparent activity. At that point I can log into the Pi via the terminal, and I note that the installation log does include a "Stage 2 started" entry.

Any ideas on how to proceed with the installation would be appreciated. The DSI touchscreen is nominally functionally equivalent to the official Raspberry Pi screen (V1), so I was wondering if the presence of this screen could be related to the problem.

Thanks and 73,
Stan NJ6E

Hi Stan

The Portsdown 5 is not yet formally released and does not have even 50% of the Portsdown 4 functionality. DATV transmit capability is proving particularly difficult to implement.

During the development process occasionally I have released builds that have been broken, and you have caught one of those.

I am about to push a new release that fixes the stage 2 build problem, but there are still quite a few other bugs that cause the system to stop responding. However, DATV receive, Stream Viewer and LimeSDR BandViewer are quite robust as long as you do not try to use the "View Snap" functionality.

More details in my talk in CAT 25 on Saturday.

Might be worth hiding the builds to avoid this.
