I have been using the oeSENC charts
since they became available on my Linux
machine. They have worked well. I have just upgraded to the new oeSENC to get the latest charts
, however, there appears to be a problem on both my Ubuntu based machine (Linux Mint 19) and my Raspberry PI 3B.
If I am zoomed in showing a small area it all works OK. If I zoom out to show a much bigger area the display starts to suffer "grey areas" rather than the chart. At this point opencpn
will crash a little while after these areas show. On the Linux
machine the following is shown in the journal:
Mar 02 08:07:52 mishka kernel: opencpn: segfault at 4 ip 00007f27ee7cdc45 sp 00007ffdcf57bf00 error 4 in liboesenc_pi.so[7f27ee705000+19d000]
Mar 02 08:09:17 mishka kernel: opencpn: segfault at 4 ip 00007f7b5d982c45 sp 00007fff29462bb0 error 4 in liboesenc_pi.so[7f7b5d8ba000+19d000]
Mar 02 08:20:00 mishka kernel: opencpn: segfault at 4 ip 00007fbe2e670c45 sp 00007ffe9cc65c20 error 4 in liboesenc_pi.so[7fbe2e5a8000+19d000]
This is from three separate crashes but shows that it occurs in the same location within oeSENC. This is on OpenCPN
version 5.0.0 .
On the Raspberry PI 3B the same grey areas occur but in the system journal lines showing 'kernel: [drm] Resetting GPU' occur. At this point the PI is essentially locked up and takes 5 or more seconds to respond to any input. OCPN may crash or lock up the PI to make it unusable unless I can zoom in more. The CPU consumption
goes from ~10-20% to 1% at this time.
The zoom level, i.e. how far out I can zoom, is considerably less than on the PI than the Ubuntu machine.
Due to the slowdown on the PI and the inability to interact with it I cannot get a screen
shot of it happening.
