General issue report

Hello there,

When tried to compile the deep_sleep and deep_sleep_wake_stub example target for ESP32H2, it fails at linking,

Tried light_sleep example and it works as described.

Note: For ESP32C6 target both deep_sleep and deep_sleep_wake_stub works as described as well.

Hi @absoluteabutaj! I have tried to build the following examples for master (v5.2-dev-3220-gaa3b9df), they are built without any errors.

• esp-idf/examples/system/deep_sleep_wake_stub
• esp-idf/examples/system/deep_sleep

Please check your IDF version to which chip it supports https://github.com/espressif/esp-idf#esp-idf-release-and-soc-compatibility. Probably you need to update your IDF barch to get it.

Hey @KonstantinKondrashov - Thanks for sharing.

Switching to the master branch did the trick. Would you mind sharing the diff for tag v5.1.1 and master branch if possible, specific to this issue?

[KonstantinKondrashov]

@absoluteabutaj For your branch tag v5.1.1, it is not supported, please check the page - https://github.com/espressif/esp-idf/tree/v5.1.1/examples/system/deep_sleep, there is no ESP32-H2 mark (see the picture below). However the release/v5.1 branch has it. You can try switching to this branch then.

@KonstantinKondrashov - Thanks for clarifying this.
