SAMA7D65 Curiosity Kit
Overview
The EV63J76A (SAMA7D65 Curiosity Kit) is a development kit for evaluating and prototyping with Microchip SAMA7D65 microprocessor (MPU). The SAMA7D65 MPU is a high-performance ARM Cortex-A7 CPU-based embedded MPU running up to 1GHz.
The board allows evaluation of powerful peripherals for connectivity, audio and user interface applications, including MIPI-DSI and LVDS w/ 2D graphics, dual Gigabit Ethernet w/ TSN and CAN-FD. The MPUs offer advanced security functions, like tamper detection, secure boot, secure key stoarge, TRNG, PUF as well as higher-performance crypto accelerators for AES and SHA.
The SAMA7D65 series is supported by Microchip MPLAB-X development tools, Harmony V3, Linux distributions and Microchip Graphic Suite (MGS) for Linux. The SAMA7D65 is well-suited for industrial and automotive applications with graphical displays support up to WXGA/720p.

Programming
Prerequisite
Before Zephyr runs on SAMA7D65-Curiosity, at91bootstrap (the second stage bootloader for Microchip MPU) needs to run first. It will initialize the peripherals and memory controllers, download and jump to Zephyr entry point.
Loading the firmware
Using a bootloader compiled with sama7d65_curiositysd1_zephyr_defconfig configuration, the binary for Zephyr (zephyr.bin) copied to a SD card can be loaded and run on the SAMA7D65-Curiosity board.
