Support of ESP32-P4

[VojtechBartoska]

This issue is tracking adding support of ESP32-P4.

Initial support for basic functions already merged in release/v3.1.x. Now working on checking if the peripherals work as expected and fixing what is found broken.

---

Oficial announcement is available here

---

ESP32-P4 is fully supported in ESP-IDF v5.3, this version is used in Arduino Core v3.1.0

Hello,

table updated, most of peripherals are already supported.

The ESP32-P4 has 16 or 32MB PSRAM built in. Is that picked up automatically if configured?

[me-no-dev]

@mutatrum yes. Just enable PSRAM and it will pick it up

Hi @me-no-dev ,I was wondering about the example program to drive es8311 using ESP32-P4 on Arduino and will it support ESP-ADF's numerous voice frames?

[me-no-dev]

@Y1hsiaochunnn we do not import ADF, so if you want to use one of it's features, maybe you should use Arduino as IDF component.
Here is an example program with 8311 driver:

Hi, @me-no-dev ,I tested the program and it worked fine. My ESP32-S3 SDK v3.0.7 tests also worked fine (pointer definition is a little different). I think this code is ready to be published in the sample application.
