IMX8QM SDK2.9 PWM driver missing

[AhmedMobarez]

Hello everyone,

I just started using IMX8 QuadMax, going through the reference manual I can see that there are multiple ways to generate PWM, which are:

- TPM module : fsl_tpm.c , fsl_tpm.h

- FTM module : fsl_ftm.c, fsl_ftm.h

- PWM module : No driver available

In the latest available SDK2.9 there is no "fsl_pwm.c/.h" drivers available, is there something I am missing ? 

please let me know if this driver is available or not, I know it should be there as it is mentioned in the datasheet and also the online SDK https://mcuxpresso.nxp.com/api_doc/dev/1523/a00063.html

I would like to use the PWM module rather than the other ones as I have more PWM pins available on the board I am using.

Thank you

Hi @AhmedMobarez,

Yes, you are right, there is no build error or anything that you have missed. But for i.MX8QM, there is no specific PWM driver support.

One can take reference of "/boards/mekmimx8qm/driver_examples/tpm/".

Best Regards,

Hello @Dhruvit ,

Thanks for the reply

Is there any plan for supporting the PWM module ? if not, is it possible to port the pwm.c/.h from another SDK for use with the IMX8QM ?

Thank you

Hi @AhmedMobarez,

There is no update planned related to this PWM driver for i.MX8QM as of now.

Yes, one can port the pwm.c/.h from another SDK for use with the IMX8QM, but NXP does not provide any support for it.

Thank you.

Best Regards,
Dhruvit.
