New Raspberry Pi 5 and OpenCPN

[Hakan]

Christophe..
I also think I have experienced slowness using X11. Not for views on OCPN but when starting other programs like the browser.
The lack of OpenGL I actually have seen as well. I thought it was something I introduced while testing other things but when you say the same it may be a result of the Wayland mismatch where OCPN during the process has disabled OpenGL in the config file.
To again get OpenGL using X11 try to:
- close O
- Open ~/.opencpn/opencpn.conf
- Set: "OpenGL=1"
- and "DisableOpenGL=0" (This may have been set to "1" ?)
- Save and restart OCPN


Let's hope the RPi developers can fix the drivers for Wayland or O find a work around.
It may be @bdbcat can elaborate my simple thoughts?

Hi Hakan,
finally I reinstalled bookWorm and with advices everything is fine now.
Thanks for your help.

Is there much noticeable difference running opencpn on a Pi5 compared to a 4?

4 was plenty fast enough I thought.

Pi5 seems faster but maybe just me. It will be nice when OpenPlotter is ported to Bookworm.

I'm running OC on Pi5/Bookworm/X11.


Works great, OC startup time is just a few seconds now and scrolling is quicker than ever. Noticeable improvement.


Browsing (Chrome/FF) is also much much faster on the Pi5 vs Pi4. btw, I disabled Wayland in favor of std X11 for several reasons including keyboard app support.


The only current issue I have is w/ my build (latest git pull) of OC, the depth isn't showing on tactics, dashboard tactics or watchdog, even though a valid DPT/DBS is being read from signalk 10110 tcp port. Tried DBK and others, no luck.

Just tested the Ubuntu Manti Minotauer version on the RPI5. OpenCPN flatpak 5.8.2.-1.

SignalK-server

This version works very well also with two finger command on my 10" touch screen I use on the boat.

Raspi OS (Bookworm) with flatpak O on Wayland has still the problems with piano bars.

BBN Marine OS with OpenCPN and plugins for raspberry pi5/4 test images based on Bookworm Debian are out. Download and install on your pi5/4 and report issues if you want to help.

Fair winds!

Test builds are available at

Just tried the new Raspberry Pi 5 with the flatpak OpenCPN.

First using the latest RaspiOS 64 on the basis of Debian Bookworm.

Can be installed from the internet. Works direct out of the "box".

Then the latest Ubuntu Mantic Minotar 23.10. But that did not work. You have to add the following sentence to the config.txt

os_check=0 .

Working twice as fast as the RPi 4 with the same power consumption of 4-6 Watt.

Debian Rawhide does not work yet on the RPI 5.

I'm new to this raspberry pi tech and opencpn. I needed a winter project to keep me busy so purchased the Pi 5. I am fairly tech savvy, have dome a fair amount of computer programming, but having issued getting opencpn installed.

Care to elaborate on how this is done? I keep getting errors trying the flatpak route. Thanks!

Hi,
I have power problems when connected aboard.
I have a 12v/5v converter 10A. When I plug a GPS antenna on the USB port, the rapi5 shutdown after about 5 min.
If I unplug it, it seems ok, but when starting or shutdown the inboard engine, it shutdown again.
Do I have to add a voltage stabilizer ?
Do anyone have an idea to solve this ?
Thanks and happy Christmas to everyone.

I'm not pro but I'd guess some dirty power. Your idea of a power buffer makes sense to me, see what those in the know have to say. Following.

I got it figured out! Stupid mistake using the wrong image ��

[cliaco]

Thanks !

cliao..
My experience is normal (long) power USB cable is often with very thin wires causing voltage fall as soon power, amps, increase. Then the 10 A converter doesn't help. I once measured using a 1 meters "normal" cable. 5.13 V at the converter. At start up 4.82 V at the Rpi5 GPIO pin.

Thanks Hakan, I will try this.
