[I] ESP32S3: LEDC does not have output. [nuttx]
w2016561536 opened a new issue, #11476:
URL: https://github.com/apache/nuttx/issues/11476
## Problem:
Use the examples of pwm in nuttx. Execute the command ` pwm ` in terminal. The output is always LOW (GPIO 2, the default pin of channel 0). And I'm sure the hardware is OK because it can works in idf. More accurately, the GPIO2 is floating after reset, and connect to ground after execute the command.
## Test conditions:
Configs: ` esp32s3-devkit:pwm `, no changes.
Hardware: ESP32S3-WROOM-1(M0N4R2)
## More tests:
It seems that ` PWM Mutiple Outpur Channels Support ` does not open. So I open it and configure the examples of pwm channel to 0 and 1 (default is 1 and 2). Test again. Nothing changed, except GPIO 3 output low either.

Hi @w2016561536 thank you for reporting this issue, when I tested it last year everything was working fine. @tmedicci do you know if it stopped to work?

I have found the problem of ledc does not have the output. I am trying to make it better to fit for a wider range of frequency. Thanks for your contributions!
