Linux/TLV320AIC3105: Building PWM drivers issues

Bruce Gao

Part Number: TLV320AIC3105

Tool/software: Linux

Hi,

I tried to build eHRPWM and eCAP drivers for tlv320aic3105 with Linux kernel (Linux arm 4.4.68-ti-r106) following the procedure from the link below

http://processors.wiki.ti.com/index.php/Linux_Core_PWM_User%27s_Guide

but, /sys/class/pwm fold is empty.

Is there something I need to do to see the devices in the folder?

Thanks,

Bruce

This wiki is valid for Arago linux kernel that comes with TI SDK. I would suggest you to switch to TI SDK or at least to compare your kernel config with TI SDK Arago kernel config.
