Errors with PWM usage on Up4000 Windows IoT Core

RenUpUser

Hi,

I am trying to use PWM on the Up 4000. I have created my Windows IoT Core image following your instructions here, and it successfully boots and GPIO works fine. I'm also running with the Up Framework.
I have downloaded your sample, however this does not seem to run. The code:

controller = await PwmController.GetDefaultAsync();  

Fails to run with error:

"Could not set desired frequency."

I have configured the pin in the BIOS for PWM. What am I missing please?
Thanks.

Hi Sir

I tested PWM with Windows 10 IoT 21H2 and bios UPAPBM12.
I can set the frequency and duty without any problem.
Please reference the attachments.
