Upgrade to OC 5 on Pi with Jessie

Hi,

tried to update my RPi with Jessie (not Stretch) from OC 4.8.8 to OC5.

I)n the ppa there´s no OC% in the "Trusty" - Area. When trying to set the repo to the "xenial" Version I´m not able to update cause of problems with the pakets.

So do I have to upgrade to Stretch first (it was much slower then Jessie)?

Then next question: The plugin for the Navico-Radar was br24radar and now just radarPi. But I don´t find it in the ppa??

Thank you guys for your hard work

Regards

Andreas

No, sorry for the delay. The radar_pi team has been busy with O V5 adaptation to get the overlay to work on both canvas for all OS. For the very moment it's being updated to also support the Navico Halo type. Give us a couple of days and I think it'll be ready.
Here's a bit dated test installation package but no PPA.
https://github.com/opencpn-radar-pi/radar_pi/releases
The actual code is at the same Github.

I think that's intentional. It's to old. Ubuntus support is soon running out.
Please upgrade.

Re: Upgrade to OC 5 on Pi with Jessie

Hi,

@Hakan: Sorry for beeing so impatient
@cagney: Thomas, the prob is, that when I try to update my pi from jessie to scratch that this will slow down my pi. When using jessie oc will run fine, with Stretch it´s noticeable slower.

When trying it with Stretch and the xenial ubuntu ppa it works but very slow with raster Charts.
With my oesenc Charts OC5 crashes, this is cause the oesenc-plugin. Can´t fix this this evening, try it later.

Maybe I´ll try it with a pretty new Stretch-Version, not with an updated jessie to Stretch Version. But this means much work for installing and get my wlan remote path to work.

But I´ll do this later and only with a chance of sucess and useable oc.

Does anyone have a pi2 run with Stretch and oc 5 here?
What are the experiences (Speed, stable, etc)?

One of the advantages since yet was that OC runs fine with the low power System pi2 (and don´t need much electrical power)

Thanks.

Regards

Andreas

Re: Upgrade to OC 5 on Pi with Jessie

Andreas...

You can also build OpenCPN from sources, should not be a problem as we still use Trusty for the CI builds. We might make the PPA build work for Trusty at some moment when there is no bigger and tastier fruit hanging lower and if it is not completely retired before...

Re: Upgrade to OC 5 on Pi with Jessie

Andreas,

OpenGL driver for RPi has been improved recently. Maybe that will solve the slow speed on raster charts.

Re: Upgrade to OC 5 on Pi with Jessie

Hi,

@nohal:Pavel, yes building from source is also an option. I understand when you guys don´t find the time to build all versions and that the non existing trusty-Version is just a question of time

@transmitterdan:I use the latest kernel for my pi (pi 2 model B) wich you can "official" get via download and update.
It doesen´t matter if I use Stretch or Jessie. It´s then the same OpenGL Driver.

When I compare Jessie and Stretch then I see that OC 4.8.8 is noticeable slower (not very much but noticeable) when using raster or vector charts. Zooming and panning is under Jessie much more usable then under Stretch.
So I decided to stay with Jessie since now.
This experience (Stretch is slower then Jessie) is also reportet in some rpi Forums, so it´s not only my "problem".
When I compare my "home brewed" rastercharts (scanned and georeferenced from papercharts) with the osenc vector Charts then OC runs faster with the vector Charts.

So, when I tried OC5 under Stretch yesterday I had a prob with the osenc plugin (OC crashed) and for the first try I used the raster Charts.
In comparison to OC 4.8.8 it was slower (25%). What happens when using vector charts I don´t know yet.

But I have to say that I tested an updatet (Jessie to Stretch) Stretch, not a new one.

Regards

Andreas

Re: Upgrade to OC 5 on Pi with Jessie

Andreas..
Yes, I've a RPi 3B and Rasbian/Debian Stretch.
I always build from source and have never tried a PPI. Won't take more then 2-3 hours to built!
I use to have the inbound OpenGl switched off in Raspi-config for best performance. I've a feeling that one will clash to what's used by OCPN?

Hi,

@Hakan: Håkan, yes, I also build from source in the first days of using the Radar plugin cause of some Errors. But then I switched back to the ready-build packages.

You wrote you switched the in build OpenGL Driver of. This is a point I don´t understand.
When using the Radar plugin I Need OpenGL. Does OC5 have an inbuild OpenGL Driver?
Since yet I thought I have to Switch OpenGL in the raspi-config on.


Regards

Yes, radar_pi do need OpenGl.
And yes I've switched it off in raspi-config. O will find a OG-driver version 3.0 Mesa.... I didn't care why it works so far. Try it!

Re: Upgrade to OC 5 on Pi with Jessie

Håkan,

switching to stretch now. Yes, it´s possible to disable the pi OpenGL Driver in the raspi-config.

The vector charts are still slow while panning and zooming.

But I still have probs with the oesenc-plugin (OC crashed), so I can´t test this.

Regards

Andreas

Re: Upgrade to OC 5 on Pi with Jessie

Håkan,

so now I managed to bring the oesenc vector charts on the screen.
Same thing. Zooming and panning of the vector charts is terrible slow.
Nearly useless.

Using Stretch updated and upgraded.

Doesen´t matter if switching the rpi-opengl Driver on or off

Overclocking does not have a great effect.

It seems that a raspberry pi 2 b have not enough cpu and gpu power for OC5?

Regards

Andreas

Yes, the 2B may be ready for retirement or dedicated to other things. I bought my 3B when it first showed up so I haven't used the 2B for a year or so.
