Hi,

starting from your Fedora VM without modifications, fsimx6-V3.0, but also with fsimx6-V3.1:

I select the following packages:

Then:

Finally, in the generated filesystem I have the packages selected, except PostgreSQL Plugin.

If, instead of the above, I *only* select PostgreSQL Plugin, it will be in the filesystem.

This is maybe a bug, or a dependencies issue?

Thanks in advance!

I answer myself, and to people who have this problem in the future:

I was not able to find Qt5 PostgreSQL (nor another database) plugin in buildroot packages menu, but, it is! Target packages -> Graphic libraries and applications (graphic/text) -> Qt5 -> qt5base -> PostgreSQL Plugin.

If you navigate to that path you will not see the plugin, and there is no way to find it through the buildroot search.

What I have done to find and install the plugin is to search the parent level (qt5base) in buildroot search, and you will see the "hidden" packages.

I do not know if this is a bug when looking for a package, but this is a strange way to find it.

Thank you so much, following that document I have been able to remotely execute and debug my application.

Ok, thank you! Let's see if someone can help me

Best regards

Any tips on this?

Hi,

I have Qt5 and PostgreSQL working, and I want to connect my Qt application to my PostgreSQL database.

Please, could you help me with this?

Thank you in advance!

Hi,

I have an issue executing and debugging Qt applications on armStone. Until now, my workaround is to manually download my application to armStone with tftp and execute it.

For remote execution and debugging, I follow section 4 of Quickstart with F&S Development Machine. I create the root file system with the additional packages. I have SSH configured, and I check the connection in Qt Creator: OK. I adjusted the paths of cmake, debugger, qt, kit, etc. I have qmake working. The application compiles without errors and the executable is created. All of this is working well.

But, when I click on debug symbol I see the following message:

Quote

Debugging starts
Listening on port 10000
Remote debugging from host 172.17.144.55

and after a while:

Quote

The gdb process has not responded to a command within 40 second(s). This could mean it is stuck in an endless loop or taking longer than expected to perform the operation.
You can choose between waiting longer or aborting debugging.

The application is not copied to /tftpboot/, therefore none of the subsequent steps is working.

Thank you in advance!

Any tips on this?

Issue solved applying your solution.

Thank you!

Thank you for your response.

But, where is that information? According to armStoneA9r2 GPIO reference card:

• Pins 4, 6, 8 and 10 are SPI_B
• Pins 18 and 20 are UART_D_TXD and UART_D_RXD, respectively
• Pin 19 is UART_B_RTS

Thank you!

Hi,

I have a very strange issue with a Qt5 application.

When I run my application, a new mouse cursor appears, so I have two cursors: one black (the system cursor, I know it because of its color and position on the screen do not change) and one white (my application new cursor). Both cursors are on different locations on the screen, and they move synchronized when I move the mouse. Even if I click, the white cursor interacts with my application, while the black one interacts with the desktop or window manager "in the background", and sometimes I can see the desktop blinking, for example when the black cursor is above an icon at the moment of the click. Very strange.

I am using Qt5, cross-compiled wih Qt creator in your Fedora VM. This happens while there is matchbox desktop or twm window manager running, with -qws arg when launching the application and without it. I see this message when I execute my application:

Any tips? Thanks in advance!

P.S. - When I compiled Qt5, I got the error that -lpcre (perl regular expressions compatibility library) cannot be found, so I ran make -k and it finished OK.

Hi, siteco.desarrollo,

in my case, ssh worked out of the box. I only had to configure it as indicated in section 4.3 of this document https://www.fs-net.de/assets/download/docu/common/en/Quickstart with FS Development Maschine.pdf

And, if I want to regenerate the keys, I do

before starting sshd again.

Hi,

you could try this:

In sshd_config, write this:

And set the current date (with date command) before starting sshd again, to generate the keys properly and not to get an expiration error.

Hi,

I wanted to use pins 4, 6, 8, 10, 18, 19 and 20 as GPIOs, so I commented the following lines in armstonea9r2q.dts:

Now I have those pins working fine as GPIOs, but I have lost the serial debug port (pins 53..61). I wonder if this issue is related in some way with the lines I commented or it has nothing to do with it.

Thanks in advance!

Hi,

I finally solved this issue.

Thank you!

Hello,

I have the same issue with GPIO in armStoneA9r2 with V3.0, and V3.1 too.

I have modified armstonea9r2qdl.dtsi as said in #post13713, but I am still not able to toggle the value of any GPIO, pins are always high (I measure the voltage with a voltmeter).

Is this a known issue? There is a workaround for this?

Thanks in advance!
