Getting Mali Graphics Debugger to work on Xiaomi Hongmi 1s - "No trace data to display"

Hi Elan,

Did you ensure the application was force-closed before you started tracing? After installing libGLES_mgd.so onto the device, the process must be completely killed in order for the runtime linker to link in the MGD interceptor. Android does not necessarily kill the application process when you "close" the application by pressing the home button. If in doubt, restarting the device will definitely kill everything, or you can use the task switcher/force close/etc.

The flow is:

Install MGD interceptor + mgddaemon

Run mgddaemon

Connect from host

Force close application if it isn't already

Run application

Trace should then start flowing into the GUI

Hth,

Chris

Thanks Chris!

I have traced the application correctly and get a lot of information from the MGD just now, thank you again!

This time in east Asia is midnight now, hope you buddy have a nice day.

Thanks,

Elan
