Blank screen running dolphin on Jetson TK1

[mastiff]

Hi I'm trying to get dolphin working on Jetson TK1. I've compiled the master branch on git, but when I try to load a game I get white screen. Software renderer works ok, so it seems like an issue with opengl. I've tried various settings, but no changes.


How can I troubleshoot this? I know someone got dolphin running well on TK1, there are videos on youtube, but I couldn't find any specifics on how it was done.

Things may be broken on master currently. Try checking out some older builds, maybe before 4.0-5972.

I tried downloading a new copy off git and building fresh.  I double checked Ubuntu trusty dependencies are installed.

Code:

sudo apt-get install cmake pkg-config git g++ libao-dev libasound2-dev libavcodec-dev libavformat-dev libbluetooth-dev libgtk2.0-dev liblzo2-dev libopenal-dev libpolarssl-dev portaudio19-dev libpulse-dev libreadline6-dev libsdl2-dev libsfml-dev libsoil-dev libsoundtouch-dev libswscale-dev libusb-1.0-0-dev libwxbase3.0-dev libwxgtk3.0-dev libxext-dev libxrandr-dev zlib1g-dev

then i ran

Code:

git checkout 4.0.2

cmake using flags for arm a15 quadcore processor

Code:

cmake -DINSTALL_UDEV_RULES=ON -DCMAKE_C_FLAGS="-march=armv7-a -mthumb-interwork -mfloat-abi=hard -mfpu=neon -mtune=cortex-a15" -DCMAKE_ASM-ATT_FLAGS="-march=armv7-a -mthumb-interwork -mfloat-abi=hard -mfpu=neon" ../

then run

Code:

make

breaks here:

lol, never ever 4.0. That shit is one and a half year old :/
Through the video backend of 4.0 may be compatible with the nvidia driver, the ARM jit isn't working (read implemented) at all.

Well I tried again with another version. I got upstream-master 4.0-5622 compiled and this time the game seems to load (at least it's showing around 60FPS) but screen is still white. Terminal output is only: Dispatcher is 0xa7d2e01c

Ok, I think I was confusing the ARM jit issue with video related issues. It seems like opengl is working so long as I change CMakeLists.txt to set(USE_GLES 0) for arm arch. cmake shows the correct files nvidia opengl files located.

Which version should I use for jetson? It's arm a-15, ubuntu 14.04, runs opengl 4.4.

I see now others have observed the issue and a temp fix was proposed.

What's the best/easiest path for me to get dolphin running in the interim until a permanent fix is implemented? What version or fork do I need to use, and are there any other changes I'll need to make?
