Summary

https://docs.waveshare.net/ESP32-P4-WIFI6

The ESP32-P4-Pico is a multimedia development board based on the ESP32-P4 microcontroller. It offers a rich set of human-machine interfaces, including MIPI-CSI (integrated image signal processor ISP), MIPI-DSI, SPI, I2S, I2C, LED PWM, MCPWM, RMT, ADC, UART, and TWAI. Furthermore, it supports USB OTG 2.0 HS and features an onboard 40-pin GPIO expansion interface, making it compatible with some Raspberry Pi Pico expansion boards for broader application adaptation. The ESP32-P4 uses a 360MHz dual-core RISC-V processor, supports up to 32MB of PSRAM, and features peripherals such as USB 2.0, MIPI-CSI/MIPI-DSI, and H.264 encoding, meeting the needs of low-cost, high-performance, and low-power multimedia development. In addition, the ESP32-P4 integrates digital signature peripherals and a dedicated key management unit to ensure data and operational security. The ESP32-P4-Pico is designed for high-performance and high-security applications, meeting the needs of embedded systems in areas such as human-machine interaction, edge computing, and I/O expansion.

Product Features:
Processor: Features a RISC-V 32-bit dual-core processor (HP system), equipped with DSP and instruction set extensions, a floating-point unit (FPU), and a clock speed up to 360MHz.

• Features a RISC-V 32-bit single-core processor (LP system), with a clock speed up to 40MHz.
  Memory:
  128 KB of high-performance (HP) system read-only memory (ROM).
• 16 KB of low-power (LP) system read-only memory (ROM).
• 768 KB of high-performance (HP) L2 memory (L2MEM).
• 32 KB of low-power (LP) SRAM.
• 8 KB of tightly coupled system memory (TCM).

The package includes 32 MB of internal PSRAM and 32 MB of onboard Nor Flash. Peripheral Interfaces: The board has 2 × 20 header pins and 27 remaining programmable GPIOs. Onboard speaker and microphone interfaces allow for ideal audio functionality using codec and amplifier chips. An onboard MIPI-CSI high-definition camera interface supports full HD 1080P video capture and encoding, integrating an image signal processor (ISP) and H.264 video encoder, supporting H.264 & JPEG video encoding (1080P @30fps), facilitating applications in computer vision, machine vision, and other fields. An onboard MIPI-DSI high-definition display interface integrates a pixel processing accelerator (PPA) and a 2D graphics acceleration controller (2D DMA), supporting JPEG image decoding (1080P @30fps), providing strong support for high-definition display and a smooth HMI experience, facilitating applications in smart home control screens, industrial control screens, vending machines, and other scenarios.

Impact

Hardware: Adds board support for the Waveshare ESP32-P4-PICO-WIFI development board (ESP32-P4 rev v1.0, 768KB HP L2MEM,）. On rev < v3.0, the non-contiguous sram_high (384KB) is now added as a second heap region, increasing available heap from ~500KB to ~620KB.
Build: New Kconfig option ESPRESSIF_FLASH_32M for 32MB flash support. New board target esp32p4-pico-wifi-wareshare with nsh, spiflash, and nsh2 configurations. Requires CONFIG_MM_REGIONS=2 for dual heap and CONFIG_ESP32P4_SELECTS_REV_LESS_V3 to bypass chip revision PANIC on rev < v3.0
Compatibility: No impact on existing boards or configurations. PSRAM driver is not yet available upstream. Boards targeting rev < v3.0 must explicitly opt-in via Kconfig to boot.

Testing

1. ./tools/configure.sh esp32p4-pico-wifi-wareshare:nsh
2. make CROSSDEV=riscv32-esp-elf- -j$(nproc)
3. esptool.py -c esp32p4 -p /dev/ttyACM3 -b 460800 --before default_reset --after hard_reset --no-stub write_flash 0x2000 nuttx.bin

Hi @Otpvondoiats , why did you close this PR? Doesn't it make sense anymore for some reason?

Still under testing, will reopen later.

@Otpvondoiats another thing: you missed the board Documentation, although you almost created one in the Summary :-D
