Having installed the Unified Multitouch driver
it does not load on boot
all Registry settings are correct
sometime it will boot once then never again
Having installed the Unified Multitouch driver
How did you determine that the driver was not loaded?
we know the status of the driver by using the dbg.Serial output on a terminal
on boot if it loads we get UnfdMutiTchDrv 2.0 loading…done
if it dosent load we get nothing no error
until we try and load the HwAdapt then we get an error
MultiTchHwAdapt loading…no Unified Touch Driver…aborted
this loads and works with a new module then for no reason will just stop working
we have the touch screen running it is calibrated then the driver just stops loading
nothing seams to rectify this until I re flash the module
it appears to stop loading if I run the I2C tool (scan the bus)
I have re flashed 3 modules and it loads every time until I run the I2C tool and never loads again after that
@Malc and @alex.tx - we are having the same issue here as well!
The unified driver works only for a short while, after a clean image install and driver install. Then it stops loading. Have you found a solution?
We are on iMX7D 512 with WEC7.
Thanks for your support!
I still don’t understand your issue. What does it mean “Then it stops loading”? Are you getting any error messages when you trying to load driver? How you define that it was not loaded? Which display/touch controller are you using? Can you describe a repro steps in details?
We are using the FT5x06 controller.
After we installed the Unified Multi-Touch Driver, both drivers (Unified and the Adaption Driver) worked.
But after a few reboots, the Unified Multi-Toch Driver is no longer loading. Unfortunately I have no steps to reproduce.
I checked the debug output during boot and could not find any error. No attempt is made to load the driver, so the line “UnfdMutTchDrv 2.0 loading…done” does not appear.
Below you find the debug output in the case where its not loaded:

I’m very sorry, but I can’t investigate an issue if there is no way to reproduce it.
@alex.tx unfortunately, we have not yet found a way to reproduce the problem reliably.
Therefore we use a workaround in the meantime:
We have changed our hardware adaptation driver so that the touch events are no longer passed on to the unified driver but we now trigger the corresponding mouse events ourselves.
Perfect that you have found a workaround. Let us know if you need any help.
