Running the example https://github.com/esp-rs/esp-hal/blob/main/examples/src/bin/ledc.rs . If I chose a frequency higher that 16MHz no PWM output is produced. For my use case I need to produce 20MHz - 24MHz .

We are investigating this issue with IDF folks, adding status Blocked for now.

IIRC this is not a hardware issue, and now works in idf - removing the blocked label.
