Tool/software: Linux
hi.
we have a board based on am335x, for which we have used ti-sdk-am335x-evm-07.00.00.00 for developing software. the lcdc settings in the dts file, which is a copy of those in am335x-evm.dts apart from display_timings worked fine. (dts_lcd_orig.txt)
we have decided to update the software, so, switched to /ti-processor-sdk-linux-rt-am335x-evm-04.00.00.04. though the dts did not compile well, so, we have restructured it to be similar to the am335x-evm.dts in this new SDK. however, there is no activity on the display (except from the backlight): no boot logo (CONFIG enabled), no terminal. the kernel messages are:
[ 1.163806] [drm] Initialized
[ 1.167976] panel panel: found backlight
[ 1.173004] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[ 1.179664] [drm] No driver support for vblank timestamp query.
[ 1.185983] tilcdc 4830e000.lcdc: No connectors reported connected with modes
[ 1.193180] [drm] Cannot find any crtc or sizes - going 1024x768
[ 1.217403] Console: switching to colour frame buffer device 128x48
[ 1.234145] tilcdc 4830e000.lcdc: fb0: frame buffer device
i followed the Linux Core LCD Controller user guide, but it does not work. can someone advice?
thank you.
