Installation

pip install ax520tool

Usage

AX520Tool is operated via the command line. Below are the instructions to perform various operations.

Basic Syntax

python ax520tool.py -p <serial_port> [options] <command> [command_options]

• -p, --port: (Required) Specify the serial port connected to the AX520 device (e.g., COM3 on Windows or /dev/ttyUSB0 on Linux).
• -b, --board: (Optional) Specify the board name. Defaults to M5_TimerCamera520.
• -r, --reboot: (Optional) Reboot the device after flashing.
• -c, --check: (Optional) Verify firmware after flashing.

Commands

1. Write Flash

Download firmware to the device.

Syntax:

python ax520tool.py -p <serial_port> write_flash <address1> <firmware1> [<address2> <firmware2> ...]

• <address>: Starting memory address (hex 0x... or decimal).
• <firmware>: Path to the firmware binary file.

Example:

python ax520tool.py -p COM3 write_flash 0x3000000 firmware.bin

2. Read Flash

Read firmware from the device.

Syntax:

python ax520tool.py -p <serial_port> read_flash <address> <size> <output_file>

• <address>: Starting memory address.
• <size>: Number of bytes to read.
• <output_file>: Path to save the read firmware.

Example:

python ax520tool.py -p COM3 read_flash 0x3000000 1048576 read_firmware.bin

3. Erase Flash

Erase a region of the device's flash memory.

Syntax:

python ax520tool.py -p <serial_port> erase_flash <address> <size>

• <address>: Starting memory address.
• <size>: Number of bytes to erase.

Example:

python ax520tool.py -p COM3 erase_flash 0x3000000 65536

Examples

Flashing Firmware

Download firmware.bin to address 0x3000000 and reboot the device after flashing:

python ax520tool.py -p COM3 -r write_flash 0x3000000 firmware.bin

Reading Firmware

Read 1MB of firmware starting from address 0x3000000 and save it to read_firmware.bin:

python ax520tool.py -p COM3 read_flash 0x3000000 1048576 read_firmware.bin

Erasing Flash Memory

Erase 64KB of flash memory starting at address 0x3000000:

python ax520tool.py -p COM3 erase_flash 0x3000000 65536

Verifying Firmware

After flashing, verify the integrity of the firmware:

python ax520tool.py -p COM3 -c write_flash 0x3000000 firmware.bin

Note: The -c flag enables verification after flashing each file. It will never check overlapping.
