I can't seem to display those Dutch ENC charts at all.

I have the charts from here:
ENC - Fairway Information Services

If I zoom in around:
51 35.6626 N 003 36.9273 E

Then select the ENC from the bar at the bottom of the screen.

OpenCPN crashes, displaying "Aborted" if started from a terminal window.

I'll try with US ENCs later.

Cheers,
JM.

Re: OpenCPN Runs on Embedded ARM

Tried with US ENCs this evening and could not get them to display at all.

I found that the configuration->Charts->VectorChartDisplay kept reverting to display category==base and nothing checked; Could this be something introduced in the android changes ?

Tried deleting the config file and .xml files to reset everything but it did not help.

Raster charts and CM93 charts worked OK.

If I have time tomorrow, I might try disabling stencil buffer in the 4.0 code to see how that works.

Cheers,
JM.

Re: OpenCPN Runs on Embedded ARM

NahanniIV...

I found a bug in the armhf math for ENC SENC file creation. Could affect your ENC display difficulties on native arm machines.

Please try the latest github, when you get a chance. You will need to delete your existing SENC files (~/.opencpn/SENC/*.S57) in order to have new SENCs made.

Good Luck
Dave

I had files in (~/.opencpnSENC/) ? There was no (~/.opencpn/SENC/).

I deleted all config and chart files.
Built from latest source.
Tried CM93: Still a problem with dredged areas (using stencil buffer in log).
Tried US ENCs OpenCPN aborted when chart was first displayed.
Tried NL ENCs but could not get them to display at all.
BSB Raster charts worked OK, but eventually got error:
"ERROR: EGL Error detected: EGL_BAD_ALLOC (0x3003)" and program aborted.

Then I rebuilt changing glChartcanvass.cpp to force stencil buffer off.
CM93 problem with dredged area was fixed.
All other problems remained.

Cheers,
JM.

Hi, I think I have found the problem with the build of the gl cache crash. While watching OpenCPN 4.1.412 rebuild the gl compressed cache update using the command line option: "opencpn -rebuild_gl_raster_cache".
I watched the memory usage climb from around 150MB to 1.4GB in about 5 minutes. I would say for all those who have less than 2 GB of main memory this is the cause of the crash. Right now after running for 19 minutes O is using 1.4GB (76%) of main memory.

When I tried to use the command line option: "opencpn -unit_test_1" to convert the charts from ENC to SENC O crashes after just 5 charts. With each chart the memory use grows until it not only consumes all of main memory (1.8GB) but also another 2GB of the disk swap.

As just a guess, I would assume there is a memory leak somewhere.

(This board is called a Tegra-TK1, and it has (4) 2.3GHz ARM7l processors, full OpenGL 4.4 & OpenGL ES3, 2GB of main memory, SATA, USB2, USB3, HDMI, audio in & out, gigabit ethernet, mini PCIe port, Full size SD card, and 16GB onboard flash.)
This board is screaming fast. Faster that my 2.25GHz Mac Mini.

Thanks for all you do,
Freddie

Did you try running OpenCPN V4.0 ?
Seems it should run in OpenGL mode without GLShim on that board.

Have you measured the actual current consumption of the board ?

The specs are great, but it's a bit spendy.

Cheers,
JM.

JM:
Yes, you are right it does work without the GLShim however once the cache is rebuilt it is about 100 times faster.

If you are interested in power consumption then look at this page: Jetson/Jetson TK1 Power - eLinux.org

At a price of $192 plus shipping its a little pricy, but with full OpenGL from NVIDIA built in, its worth it to me.

This board not only will run OpenCPN without any headaches right out of the box, you can also watch full 1080p videos, as well as install gnuradio right out of the box without fiddling around with the low level firmware or software.

Thanks,
Freddie

Glshim and Caching are two separate things. In OpenCPN V4.0 you should be able to run with OpenGL and Caching without installing GLshim.

The current code has some problems, also, since the TK1 supports OpenGLES you may be getting GLshim built even though you don't need (or want)it.

Cheers,
JM.

Yes, again you are right (senior moment). No I did not install GLShim, because I don't need it on this board. It has OpenGL 4.0 built in, so OpenCPN uses Open GL not OpenGL-ES2.
I looked in the log and it indicates "O" is using OpenGL.

Re: OpenCPN Runs on Embedded ARM

You could install the stable version of OpenCPN like this:
Configuring Ubuntu PPA | Official OpenCPN Homepage

The current version that you are trying now is under development and mainly focusing on Android.

I would be interested in hearing how the stable version of OpenCPN works on the TK1.

Cheers,
JM.

I have not had much luck with the prebuilt versions of O. However my script only takes about 5 minutes to build the latest stable version of O, plus most of the plugins in about another 8-10 minutes.

Thanks,

Re: OpenCPN Runs on Embedded ARM

Freddie...
Any exact info behind "not much luck with the prebuilt versions"? Like for example what the problems with them are.
Unfortunately I have no ARM HW to test them so I have to rely on what Launchpad produces and so far nobody ever answered my question whether the product works or not

I tried it last week and it would not work, I don't remember the specifics though.
Tomorrow I will try again with the PPA, and let you know.

Re: OpenCPN Runs on Embedded ARM

Freddie...

Yo! My worst tester nightmare returns! Long time no hear

O 4.1.xxx has lots of changes related to armhf, both in the code, and in the build scripts. And the the linux armhf environment is substantially different from the android environment, even though they have a common processor model.

So, my question is this:
Does the gl texture cache memory growth occur in O4, also? Or is it happening only on 4.1.412 built by you locally from github? And does it eventually crash?

I have not heard about raster cache crashes under android, so far.

Also, be careful about evaluating memory footprints under linux. The philosophy of linux is: "Unused memory is wasted memory". Processes routinely overcommit physical memory, expecting that actual page faults will sort things out when the memory is really needed later, if at all. So, growth of memory for a particular process is not a problem until a malloc request actaully fails, causing a crash. This may indeed indicate a real leak.

And memory management under android is a whole 'nother beast. Automatic Java garbage collection, and no swap space, for example...

Thanks
Dave

Dave:
It's always good to hear from you. I have been lirking around for all this time, just have not had much to say.
I rebuilt from git, O 4.0.0 and guess what I see, the exact same problems for both the gl texture cache rebuilding and the ENC conversion. Crashes, although not as soon as O 4.1.xxx, but never the less, crashes. Here is a snip from the sys log:

Code:
Apr 16 09:44:35 tegra-ubuntu kernel: [57045.702459] [31904]  1000 31904   354712     4269     643   290076             0 opencpn
Apr 16 09:44:35 tegra-ubuntu kernel: [57045.702469] Out of memory: Kill process 31904 (opencpn) score 192 or sacrifice child
Apr 16 09:44:35 tegra-ubuntu kernel: [57045.710407] Killed process 31904 (opencpn) total-vm:1418848kB, anon-rss:0kB, file-rss:17036kB
So, what your saying is that it is normal for an application to continually grow in size until it uses all the available memory and then it crashes? I was watching the Chromium web browser's memory footprint as I was loading up tabs in the browser and did not notice a large increase in the memory usage.

Here is a snippet from the make log during the build of O 4.0.0:

Do you think this is a problem, having both OpenGL and OpenGLESv2 found during the same build?

Also here is a snippet from O's log file concerning the use of OpenGL:

Code:
09:23:08 PDT: OpenGL-> Renderer String: GK20A/NullRM/AXI
09:23:08 PDT: OpenGL-> Version reported:  4.4.0 NVIDIA 21.3
09:23:08 PDT: OpenGL-> Texture rectangle format: de1
09:23:08 PDT: OpenGL-> Using Vertexbuffer Objects
09:23:08 PDT: OpenGL-> Using Framebuffer Objects
09:23:08 PDT: OpenGL-> FBO Stencil buffer unavailable
09:23:08 PDT: OpenGL-> Using Depth buffer clipping
09:23:08 PDT: OpenGL-> Using s3tc dxt1 compression
09:23:08 PDT: OpenGL-> Compressed tile size: 128kb (6:1)
09:23:08 PDT: OpenGL-> Minimum cartographic line width:  1.0
09:23:08 PDT: OpenGL-> Minimum symbol line width:  1.0
If you would like, I will send the entire logs.

Thanks,
Freddie
