MicroMonitor, or uMon, is an open-source embedded system boot platform. It is a mature, target-resident environment that provides the target system with a set of capabilities that enhance the development process and add to the flexibility of the deployed application. In its simplest form, it is a bootloader used to speed up the early stages of embedded system development by providing a target independent mechanism for program/data storage as well as industry standard communication interfaces for transfer of data to/from the target.
As a part of a development strategy for an organization, it provides a common base platform, an integral part of the application itself, providing the system with a core set of features that are generic in nature, and should be useable by application code regardless of the operating system chosen.
A fully enabled MicroMonitor platform includes:
- Extensible built-in flash file system (TFS)
- Support for JFFS2 and FAT
- TFTP client/server for network file transfer
- Xmodem for serial file transfer
- On-board ASCII file creation (i.e. target resident file editor)
- File-based scripts with conditional branching
- ASCII-script-driven startup options
- Command line history and editing
- UDP and RS232 based command line interaction
- Versatile configuration management using files
- Symbols and shell variables
- Symbolic display of variables, stack trace, runtime profiling and memory-based runtime trace
- Gdb server for application loads and post-mortem analysis
- Network host supporting ICMP and DHCP/BOOTP as a startup option
- Syslog client
- Zlib-based decompression
- Password-protected user levels
- Large API to hook the application to facilities provided by monitor
- Frame buffer interface, with variable sized fonts and bitmap
generation.
Here are a few examples that are simply running uMon scripts:
