			Q4: Which ESP-IDF version is recommended for ESP32-P4?
			</div>
			<div class="mw-collapsible-content">
			A:This message means the firmware's ESP32-P4 chip revision configuration doesn't match the chip on your board. Do not use --force to skip the check — rebuild with the correct chip revision instead.

			The ESP32-P4 Platform repository provides shared configuration files:

			* rev v3.1 or later: config/esp32p4_rev_v3_1.defaults
			* rev v3.0 or later: config/esp32p4_rev_v3_0.defaults

			Q5: Can the development board be powered by both USB Type-C and PoE at the same time?
			</div>
			<div class="mw-collapsible-content">
			A: Yes, it does not affect power delivery.

			<div class="toccolours mw-collapsible mw-collapsed">
			<div style="font-weight:bold;line-height:1.0;">
			Q6: What is the maximum camera resolution supported by ESP32-P4?
			</div>
			<div class="mw-collapsible-content">
			A: During functionality testing, we have validated several features. Currently, there are developments such as using a Cat-4 module to provide network connectivity for the P4, or using the P4's MIPI-DSI to extend a host screen. However, for stability reasons, related example programs are not yet provided. They will be added to the wiki once the features and solutions are more mature.

			<div class="toccolours mw-collapsible mw-collapsed">
			<div style="font-weight:bold;line-height:1.0;">
			Q7: Can I develop using PlatformIO or MicroPython?
			</div>
			<div class="mw-collapsible-content">
			A:
			* For stability, support for ESP32-P4 in PlatformIO requires the PlatformIO community to support the Arduino-esp32 SDK version 3.1x.
			* During development, we have experimented with using MPY firmware for the ESP32-P4, which can run simple commands. However, this is still in the validation phase. Actual interfaces and peripheral applications are not yet fully adapted. Once adaptation is complete and stable, usage examples for ESP32-P4 in MicroPython will be released.
