Light-/deep-sleep support for ESP32-C6

Open jessebraham opened this issue 2 years ago • 2 comments

This will serve as a tracking issue for light-/deep-sleep support for the ESP32-C6.

Work in this area is already underway:

  • [x] https://github.com/esp-rs/esp-hal/pull/974
  • [x] https://github.com/esp-rs/esp-hal/pull/918
  • [ ] Wakeup sources other than EXT1
  • [ ] Various system state save/restore for light sleep

Please feel free to use this issue for any related discussion. I will add relevant pull requests above as they are opened.

#918 has been merged. I know this isn't feature-complete yet, @bugadani are you able to summarize what's left to do? Or should we just close this issue now?

There are two main areas that I ignored so far:

  • wakeup sources other than EXT1
  • various system state save/restore for light sleep

We now have working basic light-sleep and a few more wakeup-sources. I think for remaining features we should have separate issues as needed instead of keeping this issue open forever

I suggest closing this issue and creating new issues as needed for retaining CPU state etc. when we see a need for it. Feel free to re-open if you disagree
