What bootloader is included with the modules?
As with any embedded system, the device requires a bootloader, in the case of the microprocessor modules, the bootloader is the uCbootloader. The uCbootloader does everything a typical bootloader does and includes some very useful features in addition. uCbootloader is designed to bring up hardware to a known state and test peripherals. The bootloader then passes control over to the OS. In addition uCbootloader also manages the onboard flash device, enabling reading, writing and erasing images, environment variables or persistent objects, even upgrading itself. uCbootloader also can verify images, perform self-tests, and arbitrate between firmware images (note that not all features are available on every platform). The uCbootloader also traps errors and attempts to recover helping to prevent device lockout, it also provides system calls, a command line interface, console support and a published API.
