If you are using lvds I think your problem could be related to this https://community.nxp.com/message/860347 I use dev=hdmi in my video parameter for my display. But I tried the suggested patch in that thread and it works for me. The error is gone and the Qt application starts on the 1366x768 resolution now.

Re: [meta-freescale] Problem with touchscreen Display 1366x768 with Qt 5.9 and eglfs
Hi, the bpp was set to 16, so I set it as you wrote to 32. But the Qt application still crashes with "EGL Error : Could not create the egl surface: error = 0x3003" So on our setup a Qt application with eglfs works with a 1366x768 resolution? After setting the bpp I get a Kernel message, jfyi [ 198.087193] mxc_sdc_fb fb@0: 1366x768 h_sync,r,l: 40,110,220 v_sync,l,u: 5,5,20 pixclock=83125000 Hz I'm not sure if I understand the thing with the burst size you mentioned. Regards - Benjamin Federau Betreff: Re: [meta-freescale] Problem with touchscreen Display 1366x768 with Qt 5.9 and eglfs Hello, I met the same kind of error recently. The "bit per pixel" of the framebuffer interface should be 32, you can check/change the value in /sys/class/graphic/fb[x]/bits_per_pixel. Default bpp can be specified in DTS. I also remember that IPU configure DMA with burst size and each line will must be a multiple of this burst size. This may be related with your error for line width = 1366.
