Advanced Bootloader Features
Enhanced Flash Programming
The Picofly bootloader offers advanced flash programming capabilities, enabling efficient and controlled programming of external flash memory devices. With configurable settings and error handling, you can seamlessly update firmware and store data in external flash.
Secure Boot
To ensure system integrity, the bootloader incorporates secure boot features. By verifying the authenticity of firmware updates, it prevents unauthorized access and protects your device from malicious modifications.
Bootloader Configuration
The bootloader’s configuration allows for customization and optimization. You can configure parameters such as boot delays, error handling, and flash memory settings to tailor the bootloader’s behavior to the specific requirements of your application.
Remote Firmware Updates
Leveraging wireless communication protocols, the bootloader facilitates remote firmware updates. This allows you to update your device over-the-air (OTA), eliminating the need for physical access and reducing downtime.
EEPROM Emulation
The bootloader provides EEPROM emulation capabilities, enabling you to store persistent data in non-volatile memory. This simplifies the storage and retrieval of critical data, such as configuration settings or system parameters.
Diagnostic and Debugging Aids
| Feature | Description |
|---|---|
| Serial Console | Access to a serial console for debugging and monitoring |
| Diagnostic Commands | Comprehensive set of commands for testing and troubleshooting |
| Error Reporting | Detailed error messages and logs for easy problem identification |
Customizing the Bootloader Configuration
The picofly bootloader configuration can be customized to meet the specific needs of your project. This is done by editing the `bootloader_config.h` file.
Serial Number
The serial number is a unique identifier for the device. It is used to distinguish the device from other devices of the same type. The serial number is stored in the device’s flash memory and is read by the bootloader at startup.
To change the serial number, edit the `CONFIG_SERIAL_NUMBER` macro in the `bootloader_config.h` file. The serial number must be a 16-byte array.
Device Name
The device name is a human-readable name for the device. It is used to identify the device in the bootloader’s menu. The device name is stored in the device’s flash memory and is read by the bootloader at startup.
To change the device name, edit the `CONFIG_DEVICE_NAME` macro in the `bootloader_config.h` file. The device name must be a null-terminated string.
Bootloader Timeout
The bootloader timeout is the amount of time that the bootloader will wait for a command before automatically booting the user application. The bootloader timeout is stored in the device’s flash memory and is read by the bootloader at startup.
To change the bootloader timeout, edit the `CONFIG_BOOTLOADER_TIMEOUT` macro in the `bootloader_config.h` file. The bootloader timeout must be a positive integer value.
Bootloader Menu
The bootloader menu is a list of commands that the user can enter to interact with the bootloader. The bootloader menu is stored in the device’s flash memory and is read by the bootloader at startup.
To customize the bootloader menu, edit the `bootloader_menu.h` file. The bootloader menu is defined as a table of structures. Each structure represents a command.
| Field | Description |
|---|---|
| name | The name of the command. |
| description | A short description of the command. |
| function | A pointer to the function that implements the command. |
