Chip is ESP32-D0WDQ6-V3 (revision v3.0)
Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
Crystal is 40MHz
After jaguar update (from V ~1.13 to 1.18) the device reports brown out instead of deep sleep.
(ESP-RST-BROWNOUT ::= 9 // Brownout reset (software or hardware).
-----
Version: v1.12.0
SDK version: v2.0.0-alpha.99
Build date: 2023-09-07T13:53:42Z
runs properly

Any suggestions ?(edited)

Are you sure the device is getting enough power? Do you have any way of measuring that?
kaxori 11/04/2023 11:48 AM
yes, it works in the same condition with V1.12

Can you provide a bit more context?
From what I understand:
- you call deep sleep, but
- the device wakes up and claims that it experienced a brownout, instead of a regular deep-sleep).
Correct?

We had the brownout detector disabled in earlier versions.
It was enabled in https://github.com/toitlang/toit/pull/1795 (September 6)(edited)

I'm guessing Jaguar 1.13 was released before then.

To me this looks like the ESP32 is indeed detecting a brownout, and we just didn't report it before.
There are some boards that are known to have brownout issues. Could you tell us which board you use?
Independently: if you want to continue running without brownout detection, we (or you) can create an envelope that has that feature disabled. The https://github.com/toitlang/envelopes repository has multiple variants, and is designed to be forked. Iirc we finished the work in Jaguar to fetch envelopes from custom forked envelope repositories.

with Jag V1.12 the device wakeup code 08
with newer V device wakep code 09 (brown out)
with newer V device wakep code 09 (brown out)

The brownout detector was disabled a few releases ago.

Is it an az-delivery board?
1floitsch 11/04/2023 09:01 PM
I remember those had a regulator that wasn't strong enough
floitsch 11/04/2023 09:02 PM
Yes. It was the az-delivery: https://discord.com/channels/918498540232253480/918498540232253483/1034224170369810442
floitsch 11/04/2023 09:05 PMPower regulator 3.3V is too weak.

Maybe see if you can figure out which regulator is on that board.
kaxori 11/04/2023 10:10 PM
- onboard regulator removed
- replaced with external regulator
- updated to V1.18(edited)

- application runs without problems (brown outs)

Thank you for the right hint !
