How to added pwm support on lnux platform for rt 1052

[seven1]

HI,

I run rt1052 on linux platform, now need add the pwm function, but not found  the dts & driver file about pwm.please provide releted code .thanks.

Thank you for your reply. This is still the issue. I want to directly write registers on LInux to configure the PWM function, which registers should I configure, and what values should I configure. The more detailed, the better.

This pin is MXRT105X_ PAD_ B1_ 15_ GPIO2_ IO31, mean is MXRT105X_ PAD_ B1_ 15_ FLEXPWM4_ PWMA03。

Hi,

Customer could refer RT1050 SDK software provided PWM demo, which uses eFlexPWM to generate A-phase pwm, B-phase pwm and C-phase pwm through submodule 0, submodule 1, submodule 2. 

Related demo located at ..\SDK_2_13_0_EVKB-IMXRT1050\boards\evkbimxrt1050\driver_examples\pwm

Wish it helps.

best regards,

Mike

Hi,

Unfortunately, NXP provides MCUXpresso SDK package for RT1050 product, not support ucLinux.

Please check with EmCraft about ucLinux BSP for RT1050.

Wish it helps.
