How to generate 10ms single pulse with iMx6S ?

[IHOU35]

Hi to the community.

We are facing some trouble while migrating from Kernel 4.4.302 to 5.4.217 on our application running with iMx6S

We need to send a single electrical pulse with a controlled 10ms timing.

With Kernel 4.4.302, we used the led driver in oneshot mode with no problem.

With Kernel 5.4.217, this driver still exists but generated signal is 20ms minimum.

Is there anyone who coud help us to solve this issue, we are using the GPIO _7 (ball R3) which is not part of PWM peripheral ?

Thanks for your help

Hello @Bio_TICFSL ,

Thanks for your answer:

Try reducing the clock or try to adapt your PWM model

Could you please be more explicit: what clock are you referring to, and I remind that we don't use the PWM peripheral neither PWM driver, so there might be some misunderstanding between us.

Hello,

Try reducing the clock or try to adapt your PWM model.But this must not happens.
