@Jeepgoing it seems to me that a similar issue was discussed intensively some time ago, so look into closed issues

@zhang-peter In my opinion the Qt5 crash wouldn't mean that there was something wrong with Mali kernel module. Did you try the sample application (showing a triangle)? What userspace components...

@Jeepgoing hi if you want to get help I'd recommend you publish your build framework (scripts) on github (or any other) so that we can see what's going on there.

@zhang-peter what kind of crash is this , kernel level (oops) or user space ? what is your dmesg saying ?

@zhang-peter just to be 100% sure, could you measure voltages +5V and +3.3V on corresponding GPIO pins 1)just after reboot 2) after the crash

@zhang-peter you need to be 100% sure that your power supply is not failing before you start resolving software issues

@zhang-peter @Jeepgoing I tried your scenario and got the same issue. So we're all in the same boat. OrangePi PC Kernel 4.19.12 Qt 5.11 Mali r6p2 Mali blobs https://github.com/bootlin/mali-blobs/tree/master/r6p2/arm @mripard...

@zhang-peter That is not going to help IMHO. Something makes me think that the blob we are using isn't actually compatible with our hardware, i.e. this isn't our fault and...

I have tested sun4i DRM + wayland blob and it seems to work fine. But I can't say for sure that hardware acceleration is utilized in this configuration. lsmod shows...

I recompiled the driver in debug mode and I can finally see the driver activity, so yes, it seems like hardware acceleration is involved when using the Wayland blob.
