Field Firmware Updates
Updating firmware in the field is often a necessary part of a product life cycle.  In many cases an embedded application is not designed to update itself or has no connection to the outside world to allow remote updating. Access to a PC network or even wall power is often limited. P&E provides several solutions to allow in-circuit reprogramming of a target in an extremely simple fashion with little or no training required.  P&E tools support programming the target automatically with a single click of a button. The only requirement of the target system is to have access to the background debug header on the microcontroller to be updated.

Field Target Diagnostics
P&E’s UNIT library software development kit allows the user to create a Windows application which can fully control the execution of an embedded processor via one of P&E’s hardware interfaces. The application can peek and poke memory, peripherals, and other resources of the embedded processor through the debug mode. Applications can use this capability to perform tests of the target hardware, calculate target calibration data, or simply be a way to develop a totally custom application which controls the target via debug mode. The advantage of using debug mode is that the processor doesn’t need to be running application code or even to be programmed for the PC application to fully exercise the processor’s capabilities.
