DVI Support
How to enable HDMI Support
The default imagest doesn't support HDMI-DVI converters
REFERENCE: http://boundarydevices.com/dvi-support-on-i-mx6-boards
- In order so setup a fixed resolution, add to >uEnv.txt
video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32
Otherwise the best higher resolution will be choosen.
Hpw to enable OpenGL suport
Kind of message like this
libEGL warning: DRI2: failed to authenticate [ error ] ofAppGLFWWindow: 65544: X11: RandR gamma ramp support seems broken X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 72 (X_PutImage) Serial number of failed request: 120 Current serial number in output stream: 121
Can be solved updating all the mesa packages to the same version
# apt-get install libopenvg1-mesa libgl1-mesa-dri libgl1-mesa-dev libgbm1
How to build Mesa video drivers on a new kernel
Reference: http://www.solid-run.com/community/viewtopic.php?f=8&t=851
- Get the latest open source driver
# git clone https://github.com/laanwj/etna_viv
- Build the driver
# cd etna_viv # export GCABI=imx6_v4_1_0 # make
- Get the mesa fork for the library generated above: libetnaviv.a
# git clone https://github.com/laanwj/mesa
- Install dependencies to build the mesa driver
# apt-get -y install x11proto-dri3-dev x11proto-present-dev
- Configure the mesa driver
- First pass to try to trick the intel drivers
# cd mesa #./autogen.sh --with-driver=dri INTEL_CFLAGS=disable INTEL_LIBS=disable
- Second pass to enable etnaviv
