i seem to be unable to get the graphics to attach to any apps on the SHIELD tablet. whenever it scans processes i just get “No attachable processes found.”. i’ve tried running the debugger on OSX and windows, and with the nvidia sample apps as well as my own. does this require root? typical log output is:
Scanning for attachable processes on SHIELD Tablet …

i ended up using the root method, and i can now profile applications which is great. however, the “capture frame” button doesn’t seem to do anything? (the button is enabled, but clicking it does nothing). i’ve tried running the tegra debugger on OSX and windows with the same result - should i be able to capture frames from the shield tablet?
I/TegraGfxDebugger( 3411): [Frame Debugger Alert] Cannot enter frame debugging!
I/TegraGfxDebugger( 3411): The Tegra Graphics Debugger only supports frame debugging for GLES 3.1 and OpenGL 4.2.
I/TegraGfxDebugger( 3411): First seen unsupported operation: glAlphaFuncQCOM
the app i’m profiling is built with unity3d and i can either force it to ES 2.0 or ES 3.0 - i assume that’s the problem?
for the non-root method, there is no official documentation yet, will update within next release. If you have any problem with non-root method, please send mail to devtools-support devtools-support@nvidia.com
Hi although I am rooted I am still having an issue with permissions? I’m currently developing for the shield tablet using unity, any help would be great
