ADuCM3029 Flash Demo no-OS Example Project

See projects/aducm3029_flash_demo (doxygen) for the Doxygen documentation.

The ADuCM3029 Flash Demo is a no-OS example project that demonstrates basic flash memory read and write operations on the ADuCM3029 microcontroller. The project initializes UART, interrupt controller, and flash memory peripherals, then performs a series of flash read/write operations at user-defined addresses. All results are reported via the UART serial console at 115200 baud, providing a straightforward demonstration of the no-OS flash memory API.

Applications

Flash memory read/write verification
ADuCM3029 platform bring-up and validation
Non-volatile storage development reference

Hardware Specifications

Power Supply Requirements

The EVAL-ADICUP3029 board can be powered through the micro-USB connector (P10), the DC barrel jack (P2, +7 V to +12 V DC input), or a battery header (BT1). The USB connection provides power and also serves as the programming and debug interface.

No-OS Build Setup

Please see: No-OS Build Guide

No-OS Supported Examples

This project is organized around the no-OS variant based build flow. Selecting a variant at build time (--variant <name>) chooses which application is compiled. The platform main() is a thin dispatcher that calls example_main(), provided by the selected example. The initialization data is defined in src/common and the platform-specific macros in src/platform/aducm3029.

Flash Example

The flash example (flash variant, the default) initializes the UART, IRQ controller, and flash peripherals, then reads from and writes to flash memory at specific addresses (0x3E000 and 0x3E004). The results of each read/write operation are printed to the serial console.

No-OS Supported Platforms

ADuCM

Used Hardware

EVAL-ADICUP3029

Connections

Connect the EVAL-ADICUP3029 to a PC via the micro-USB connector (P10). This provides power, programming, and serial communication. Ensure the UART switch (S2) is set to the USB position for PC terminal access.

Build Command

Available variants: flash. Available boards: eval-adicup3029. Replace --variant / --board accordingly.
