Features

The serial flash loader uses a packet type interface to provide reliable synchronous communications. Two different UART download utilities are also supplied that can be used to program the flash using the serial flash loader. The serial flash loader application is factory-programmed into each device. Since the flash loader allows programming of a device using basic serial interface, it can be used to program a device during production when a debugger interface is not available. It can also be used to provide a method to download applications to the on-chip flash and run the application without the use of any debugger interface. In the event that the serial flash loader is erased, a downloadable binary (flashloader.bin) to reprogram the flash loader into a device is also provided.
