good to have fedback.

I have no experience with skyeye simulator and it seems that
you do not have it installed.

I have studied options for graphic support on ARM in QEMU and there
is not much options.

The found candidates

  PL110 for ARM Integrator/CP, ARM Versatile and PB-A8
     - from these only "realview_pbx_a9_qemu" seems to be supported
       by RTEMS BSP
  framebuffer for PXA255 - this could work with "gumstix" RTEMS BSP
  OMAP LCDC for OMAP1 - but that is dated

For actual OMAP3/BeagleBoard supports seems to be only in the QEMU


and even RTEMS BSP is in the development and not in the mainline tree

It is possible to try Cirrus VGA for these ARM boards which support
PCI. But I think that none of RTEMS ARM BSPs supports PCI.

RTEMS QEMU scripts seems to support DIPLAY only for GUMSTIX.
So that one seems to be only usable target.

I may look at it little more but I am out of time now.

We have never used QEMU for our Linux/RTEMS CSB336/PiMX1 development.
We have worked on real HW and for upper levels of RTEMS target SW
(i.e. graphics and Microwindows, SuiTk application logic etc)
we have used native X86 build for Xorg.

Best wishes,
