<![CDATA[T113 PWM只能同时输出一路]]>主控：t113
sdk:longan_sdk
单独使用时，每一路pwm都能够正常输出，但是同时开启多路PWM时，只有第一个被开启的有输出，后面开启的都没有输出。

platform/2000c00.pwm, 8 PWM devices
 pwm-0   ((null)              ): period: 0 ns duty: 0 ns polarity: inverse
 pwm-1   ((null)              ): period: 0 ns duty: 0 ns polarity: inverse
 pwm-2   (sysfs               ): requested enabled period: 1000000 ns duty: 500000 ns polarity: inverse
 pwm-3   (sysfs               ): requested enabled period: 10000000 ns duty: 6000000 ns polarity: inverse
 pwm-4   (sysfs               ): requested enabled period: 1000000 ns duty: 300000 ns polarity: inverse
 pwm-5   ((null)              ): period: 0 ns duty: 0 ns polarity: inverse
 pwm-6   ((null)              ): period: 0 ns duty: 0 ns polarity: inverse
 pwm-7   ((null)              ): period: 0 ns duty: 0 ns polarity: inverse

感谢大佬，果然是longan-sdk 的BUG，换上tina 就好了。

https://bbs.aw-ol.com/topic/2027/share/1 然后吧lichee/kernel-5.4 替换longan-sdk的kernel-5.4，longan-sdk里的代码太老了是测试版有bug
