Dear Biser：
Though my sdk is old ,but it is just last version sdk before the latest sdk ,and according the AM335X PWM driver's guide ,it also should work,my sdk is newer than the guide.
Can you tell me how the functional clcok to be started in the arch/arm/mach-omap2/board-am335xevm.c
In my opinion ,just enable the pinmux ,and call am33xx_register_ehrpwm(2, &pwm_pdata[1]); is enough.
What make me strange is why it show l3_slow and l4per and ehrpwm is not enabled
thank you
