Summary
Following #18492, say hello to ESP32-P4 on NuttX!
This PR adds support for Espressif's RISC-V-based ESP32-P4 chip on NuttX, supporting its ESP32-P4-Function-EV-Board board.
Impact
Impact on user: Yes. They now can start designing applications using NuttX on the brand new ESP32-P4 SoC.
Impact on build: No.
Impact on hardware: Yes. New hardware is being add!
Impact on documentation: Yes. Documentation is provided for ESP32-P4 and ESP32-P4-Function-EV-Board.
Impact on security: No.
Impact on compatibility: No.
Testing
All provided defconfigs are already being tested on our internal CI with HW in the loop. As an example,
ostestcan be tested manually.Building
Build and flash using UART0. Please note that, depending on the board version, it might be necessary to attach an external USB-to-UART bridge connected to UARTO pins and set the board to download mode. Please, check the
