Maxim Bootloader Tools User Guide
■Maxim provides generic and secure variants of flash bootloader firmware for microcontrollers that enable firmware update and protect customer IP by secure communication. This user guide provides a detailed explanation of how to communicate with Maxim bootloaders. The document should be used in conjunction with the target device bootloader user guide.
●Introduction
■The bootloader is a special firmware that loads inside the main microcontroller, and generally the purpose of the bootloaders is to load the main application and provide firmware update functionality.
■For some microcontrollers, Maxim provides the bootloader firmware that gives target microcontroller firmware update functionality and security. There are two types of Maxim bootloaders:
◆Generic bootloader (provides firmware update capability)
◆Secure bootloader (provides firmware updates + secure transfer of firmware)
■The Maxim bootloader solution is capable of handling communication over I²C, SPI, or UART interface. These bootloaders utilize a special communication protocol which is described in the bootloader user guide to configure bootloader options and perform the firmware update. Detailed information on the protocol is available in the target device's bootloader user guide.
■Maxim provides collaterals to ease the porting effort of the customer for the target platform and enable an evaluation platform for the bootloaders. The collaterals are listed as follows:
◆Bootloader Programmer Board: To enable I²C/SPI communication through USB CDC ACM.
◆Bootloader PC GUI Tool: A PC tool which provides GUI interface to configure target and load firmware.
◆Bootloader Host Example: A platform-independent bootloader host example, which can be used by the customers while developing their bootloader host.
■Bootloader-related software and tools are delivered to customers by Maxim Software Development Kit (MSDK).
■The rest of this document is structured to guide users on steps for communicating with the bootloader and porting host programmer for the target platform.
