Hello,

I see that function machine_deepsleep has a TODO for STM32H7.

Please could you help me to implement the TODO ? I should do that but i need main guide lines.

Thanks

esp32 s3 deepsleep wake

closedby stephanelsmithopened 2022-01-07updated 2022-02-01
port-esp32

Migrating to S3, one curious issue is I'm not able to wake from deep sleep. Timer wake nor the ext0/ext1 modes. I have no problem with D4 or S2 versions. I'm using the UART console on S2/S3, so I do not get disconnected on deepsleep.

import machine
machine.deepsleep(1000)

Purusing modmachine.c where looks like the important bits are, I don't see anything jumping out at me in 'machine_sleep_helper' that would make a difference on a per sku basis.

I'm on micropython master branch. What esp-idf branch are S3 folks using? I'm on a October commit b86fe0c66ca17d5907ae26ecdffc9d4eb79cec07 which is working for me. Master esp-idf is giving my compilation errors. Maybe a more recent idf version?
