Map tiles not visible on Armbian

  • Hi
    I have an application with maps in QML. Works prefectly on my Linux machine, on Armbian on OrangePi it compiles fine, but tiles in map are not visible (gray map), although there are items visible on the map, items that I add to Map. Even when I change zoom items are moving closer or further apart as with normal working map application, just tiles are not visible?
    Machine runs Ubuntu Xenial Qt version 5.5.1 I'm using "import QtLocation 5.5" and OSM plugin.
    There are no error at the application startup, however, when I disable network resolver I have the errors like:
    QGeoTileRequestManager: Failed to fetch tile (1141,675,11) 5 times, giving up. Last error message was: 'Host not found'
    With network working correctly I don't have any messages regarding maps,
    even the standard msg:
    QGeoTileProviderOsm: Tileserver disabled at QUrl("
    QGeoTileFetcherOsm: all providers resolved

    Icons for the object I have added to map looks very low quality, some problem with open GL ? framebuffer ?

    Has anyone some clues ?

    Best Regards

  • I thought it might be the problem with graphics, mali_triangle did not want to start, so I have installed mali binary driver now mali_triangle starts, triangle visible, and output is:

    still no tiles visible although map itself is working I can see items on map, even copyright visible ;)
    Any idea someone ?


  • this was OSM plugin problem with Qt 5.5.1 - does not work in this case.
    HERE, on the other hand, is willing to cooperate ;)
