Mr Zheng,

Is the information on this wiki page useful: processors.wiki.ti.com/.../Linux_Core_PWM_User's_Guide ?

Also, please note that the latest Linux distribution provided by TI for this processor is v4.0 of the Processor SDK Linux which is based on the 4.9 kernel: software-dl.ti.com/.../index_FDS.html

P.S. After AMSDK 8.0 we renamed the package to Processor SDK Linux starting at v1.0 and we are now on v4.0.

Hi Jason,
The User's guide is not very useful. Imust change the PWM in userspace.Are you understand userspace? Change the brightness of the LCD by change the PWM any any time is my purpose. And I will grade the brightness. Is there any API just like read or write that can control the PWM??
