> why? First answer is that it is not implemented. Second is that we won't work on it past experimental. You'll be on your own if you really need it on ESP32. It is not a bug, it was not implemented. > is there a known hardware bug or something? Not a bug, but its implementations is more suitable for AMP scenarios and/or a bare metal hypervisor approach. For regular, single kernel on multicore approach, it becomes quite hard to use it. > do you have a reference? Datasheet. My opinion also comes from evaluating it as a Project: too big, little to gain, something only valid for ESP32 as others are different. > why not? Ok, I oversimplified. The point is you can't simply switch PIDs. You must follow the steps on how to make it work (on datasheet). It is currently not implemented and there are some caveats on how NuttX is and what would need change to make that work. It get more complex when you throw multicore SMP in the game. Cherry on top is the IRQ control and all the changes it will require. -- This is an automated message from the Apache Git Service.
