OpenCPN on Raspberry Pi2

Built with wxWidgets3.0.2
CubieTruck OpenCPN logfile shows a bunch of can't find SVG files (looking into that) and Opencpn initialized in 9045ms.
Also see my update, to the message you quoted, things get better after caching;
Should the caching be required/forced for this type of system?

Let me try and quantify that, I may have been judging it relative to the Raster performance which I had not been able to use for a while.
I will do some more testing soon.
That it is Working is most important!

Is this comment related to my problem with the OOM Killer on the TK1 or EGL_BAD_ALLOC ?
Can the problem be fixed ? Or do I need to lower the resolution ?

I can dramatically reduce the texture memory needed, but not until after version 4.2

Can you see if there are issues with black screens with wx 2.8?

I will try it with wx 2.8, but I'm not exactly sure how to do that ?

Do I just disable newer versions using Synaptic package manager ?

Thanks,
JM.

After building the texture cache, the only time I see black or garbled screens is: at startup (about10S), on exit (about3S), and when the screen size changes (like when going full screen).

CM93 is always less than 10FPS often 2-4.

Raster charts are always >10 FPS sometimes as high as 150FPS.
But after zooming and panning eventually OpenCPN hangs with 100%cpu use.
OpenCPN is using most of the CPU, rsyslogd the rest.
The system monitor shows 60%RAM usage.
dmesg shows:

I think this is the same scenario where the OOM killer kicks in on my TK1.

You should get 30fps for raster and 15-20 for cm93 when panning. Zooming on cm93 can be very slow (1-2fps) in some cases, but hopefully this is fixed soon. I intend to use the android style canvas zooming to improve this...

Can you set the maximum texture memory to 64mb or something and see what happens? To try with wx2.8 I compile wx from source.

Tried GPUTextureMemSize=32 on the TK1 earlier in this thread at BDBCATs request, but it did not resolve the problem.

I will try wx2.8 and smaller texture memory on CubieTruck tomorrow if I can.

Thanks for all the work you have done on this.

Are you in CapeTown now? Or going soon ?

When I set GPUTextureMemSize=32 on the CubieTruck I don't run out of memory. I also had to set OpenGLExpert=1 to make this work.

I also pulled the latest from GIT.
At first I had a black screen for about ten seconds on startup, then the chart appeared. After a bit of testing that changed so that either the black screen remained until I clicked the screen, or a garbled chart remained until I clicked the screen. It's possible that this started happening after I tried fullscreen mode which did not work correctly.

The black screen on exit seems to be gone, at first I saw the crosshatching during exit, but then later mostly the chart becomes garbled as OpenCPN is exiting. Seems like a mode it gets into, rebooting will not fix it.

With OpenGL=off startup shows a white canvas for 10Sec., no garbled charts, fullscreen works, and shutdown works correctly.

It looks like wx2.8 is installed on my system, is there a way to force OpenCPN to use it ?

Cheers,
JM.

OK, I compiled wx2.8.12 from source on my CubieTruck.

What now ?
Do I need to hack cmakelists.txt ?

Sorry, I am not sure how to do this.

Did you run
make install
after compiling wx2.8.12?
If yes:
for finding wx libs cmake is using a program named wx-config
execute in a terminal:
wx-config --version-full
if you're seeing
2.8.12.1
you're set, rerun cmake as usual it will recreate makefile with the right libs.

Hello guys. I have a brand new to me raspberry PI 2 that I ordered off amazon right around thanks giving.

Robot Check

Was wondering what to do with it and then ran across this thread. Would love to set this up with openCPN and put in on my Columbia 34 Mark 2. What ever gps antenna works I will install it to make this work. Probably do a good LCD screen on an arm that would swing out into the companion way. I will take the time to read through the thread, and start investigating. Any pointers for a newbie like me would be much appreciated.

I am a heavy Linux user on my home server, and in a past life I used to be a software programmer with HP. I have compiled code, just not in a while.

I am so excited to find this because not having a laptop on the boat has been what I was thinking.

That seems to work.

The openplotter image is all you need, easy to VPN into it even without a keyboard or monitor. See this thread..

Hi,
I have built a working version of the latest beta of OpenCPN and OCPN_DRAW_PI which will install on a Raspberry PI2 running raspberian (standard OS which comes with NOOBS to install on new PI). You will find them here:

Thanks, should I use this one then? What's the difference between the OpenCPN and OCNP_DRAW_PI .....
