Re: OpenCPN on Raspberry Pi2

Champ...
Yeah - sound nice and doable but I've no printer. So I think I've to do as usual, acrylic glass or plywood.

Re: OpenCPN on Raspberry Pi2

Is the power draw .8 Amos @5v or @12v?

Re: OpenCPN on Raspberry Pi2

akopac..
Sorry.. @5V equals < 5W, but say 5W since the voltage regulation from 12V will also use some power.

Re: OpenCPN on Raspberry Pi2

it's .2 to .3 amps draw at 12 volts

Re: OpenCPN on Raspberry Pi2

@NahanniV...

Looking into your trouble with incorrect raster mipmap display on 4.1.1108.

Can you tell me your build process? I am having trouble building O with glshim on (noobs) Wheezy. I get a software rasterizer only. This works, but slow....

Thanks
Dave

I am building on a CubieTruck. The distribution is called Aruntu (Ubuntu 14.0.4LTS (I think).

I had to build and install WxWidgets 3.0.2.
Also had some difficulty getting LibCurl installed; Resolved that with Apptitude.

Otherwise the build is standard LINUX. Watch cmake log to see that it finds gGLes; On another distro, I had to hack cmakelists? to force to to assume GLes.

I don't have a Pi, but I am getting an NVIDIA Jetson TK1 for a Christmas prez. I'll let you know how that works, I am hopeful!

Merry Christmas,
JM.

Re: OpenCPN on Raspberry Pi2

JM...

OK, thanks for the info.

Sean, or anyone else have GLshim working on RPI2?

BTW, I am also working with the new OpenSource VC4 GL driver for RPI2.
Disable the GLES stuff in CMakeLists.txt, and build as for standard gtk OpenGL environment.

Latest build for Jessie seems plenty fast enough to run OCPN GUI. But there is no texture compression support, so we run out of RAM pretty fast on raster charts. I'm still learning how to drive RPI2, so there may be some tweaking to do. Not looked vector charts yet.

We get a very nice OCPN OpenGL configuration, though. VBOs and FBOs available

Code:
18:44:36 UTC: OpenGL-> Renderer String: Gallium 0.4 on VC4
18:44:36 UTC: OpenGL-> Version reported:  2.1 Mesa 11.2.0-devel (git-97eee90)
18:44:36 UTC: OpenGL-> Texture rectangle format: de1
18:44:36 UTC: OpenGL-> Using Vertexbuffer Objects
18:44:36 UTC: OpenGL-> Using Framebuffer Objects
18:44:36 UTC: OpenGL-> Using FBO Stencil buffer
18:44:36 UTC: OpenGL-> Using Stencil buffer clipping
18:44:36 UTC: OpenGL-> Using Scissor Clipping
18:44:36 UTC: OpenGL-> Not Using compression
18:44:36 UTC: OpenGL-> Minimum cartographic line width:  1.0
18:44:36 UTC: OpenGL-> Minimum symbol line width:  1.0
Comments, Sean?

Thanks
Dave

JM:
I have two Jetson TK1's, and O builds and works flawlessly on both. Quad core 2.225GHz processors make these things move. Its faster than my 2.25GHz Mac Mini. Jetson comes with full OpenGL working from the git go.
They also don't use much more power than the CubieTrucks either.

Merry Christmas,
Freddie

Re: OpenCPN on Raspberry Pi2

Dave,

I don't know if the image I downloaded with the vc4 driver was corrupted or what, but it gave me a very broken system.

So instead I used glshim with the broadcom drivers, and got pretty good frame rates. Also the FBO works, but only with power of 2 sizes...

Anyway, I have reproduced the problems on my cubie truck. No doubt it is doing something wrong with mipmaps, but also maybe something with the FBO. The old version works fine, so I have only to git-bisect. I am waiting for the first of 10 builds to complete...

Re: OpenCPN on Raspberry Pi2

Sean...

OK, thanks for helping. I never have gotten a GLshim/GLES environment running on RPI2/Wheezy. Stuck in SW renderer.

The latest Jessie image with VC4 driver I found is:
http://sukzessiv.net/~gohai/vc4-buil...-vc4-image.zip

Installs and boots with no problems. No changes needed to config.txt. Build OCPN by hacking CMakeLists to skip GLES detection, and use plain old OpenGL mode. I can do OCPN over X11 VNC link, so debugging is easier with a full size keyboard and monitor.

Today I plan to add some debug messages and fiddle with the OCPN declared texture memory limit. We are getting asserts from the VC4 driver about GL_OUT_OF_MEMORY, then a clean crash.

Vector charts work fine.

Dave

I don't know if this is relevant or not. I am trying out the TK1 Arm board and everything works well so far except if I select OpenGL mode without texture compression using raster charts. In this mode I see the busy spinner get stuck on and eventually get a crash. The debug information is not too helpful:

Code:

I also am trying to figure out how to build OpenCPN to use GLes on this system, just to see how it works.

Re: OpenCPN on Raspberry Pi2

Hi,

first a friendly hello, cause Im new here. Im Andreas, coming from Germany and sails round the netherlands coast and the North sea.
Ive read much about opencpn and the pi so I decided to start with it.
I try to run opencpn on a pi (Raspi 2 Model B). I use the build from agurney. I was sucessful, cause it works with my self scanned rastercharts of the netherlands coast.
I also get run a remote control to my android tablet via xrdp and an app (not Microsoft remote desktop-does not work) via a wlan.
But Im not able to install any plugins.
How can I install e.g. watchdog?
Im new in Linux and new with the raspi so I need a how to for dummies.
Thanks

Andreas

Try the openplotter rasp pi image, it has opencpn v4 with most of the plugins, and much more as well.

Re: OpenCPN on Raspberry Pi2

Hi,

solved the problem with the plugins but not finally. I can now install the plugin with sudo apt-get install ... and the plugin will be downloaded and istalled. But I cant see it in the plugin list under opencpn. Here are only the two build in plugins.
Ive also a problem with the settings of the plugins. After rebooting or power off the pi and starting again the Settings for the plugins are lost.

Sugestions?

Andreas

Witch version of opencpn are you running ?. Have you downloaded the image from agurney or used the script wget http://agurney.com/raspi/opencpn_install.sh ??
