galcore crash with qt application

mdilger — Mon, 25 Feb 2019 07:22:20 GMT

Hello,

we are running a linux system build with buildroot on an imx6 dual lite. We use qt webkit application as the front end.

Currently we have an issue with /dev/galcore. The qt application freezes after some period of time, sometimes it happens after 30 minutes, sometimes it takes a whole day or longer for the freeze to occur.

The qt application displays a web page which in case of the error does refresh a clock using java script and communicate with the main application using a web socket and http web service.

The kernel messages show a crash of the driver being stuck

Jan 29 17:44:44 fsimx6 user.warn kernel: DMA appears to be stuck at this address:
Jan 29 17:44:44 fsimx6 user.warn kernel: 0xFFFA8018

After that error happens the system has to be rebooted to get it working again.

Do you know similar problems or a way to debug it?

Please see the complete output of the crash in the attachment.

Hi Maik,

You can check if it is caused by GPU supply. Also one can try different gpu mem settings, recommended to have 128M gpumem, with 1G system memory, We can not reproduced since you are using build root, try to run in the BSP and see what happens.

Regards

Hi,

Can you tell me how to change the settings then i will look for it. The system memory cannot be changed because it's a COM we get from F&S, we only have these hardware configuration available.

The module is efusA9 COM

Best regards
