QT5 application on AM3352

Other Parts Discussed in Thread: AM3352

Dear Collegues,

I try to run application build by linaro toolchain and QT5 kit from SDK 01.00.00.00 on custom AM3352 board. It doesn't have SGX core. When I run it with -qws parameters I get error: could not initialize egl display. Could I run application with linux framebuffer support? What should I do? rebuild QT or specified running parameters? Applications build by QT4.8 kit from SDK6/7 works fine on this board with SDK6/7 environments (kernel,rootfs,etc).

I tried to install powervr driver from Graphics SDK but it's seems need to have SGX core for working properly.

Any help will be very appreciated!

Hello Tim,

These errors will disappear when the PowerVR driver gets installed.
You can build and install the driver by using the source from SDK 01.00.00.00 with these commands.

make sgx-modules && make sgx-modules_install

The produced objects will be placed in your $DESTDIR.

Best regards,
Kemal

Hello Kemal, I actually don't have SGX core on chip. Is it still suitable for my case? I have messages with dumps from sgx modules after installing it

Have you installed additional drivers on SDK6/7 in order to get the application work. The latest SDK 01.00.00.00 uses Qt5.4 which no longer supports qws.

I will check rootfs, but I did not install additional drivers manually in SDK6/7. It's seems like QT4.8 was OK with linux framebuffer driver

I have the same problem when install processor SDK 01.00.00.03 on AM3352. My display was dark when launching matrix gui application.
