ESP32-S2 OTA Fail

[fabesp]

Hello everyone,

I am testing OTA through the ESP Rainmaker Dashboard, but it fails on the ESP32-S2 with the following error message:


I tested the same code and configurations and successfully performed OTA on the ESP32, ESP32-S3, ESP32-C6, and ESP32-C3.

I used the examples available on the ESP Rainmaker GitHub as a reference.

Could anyone help me resolve this issue?

Thanks for reporting the issue. It seems that with newer ESP IDFs, the default RAM usage is more, leading to heap memory allocation failure as can be seen in the logs. We will check what can be done to make more heap available for OTA.

Thanks Piyush. I'm using IDF v5.1
