Getting Started with Freescale software and tools for automotive

the target 9s on-chip debug hardware. " Target system is the MCU. In the absence of an MCU, the target system can be an emulator or simulator.<br><br> Did you know? Freescale offers starter kits for many devices that include the software development tools, cables, a wiggler (debug interface), an MCU and a board needed to begin development. Examples of the software development process Development Tools www.freescale.com/automotive 3 Write, Compile, Debug With the development environment in hand and the software development tools installed on the host computer, the next task is to develop a bug-free application for the end product.<br><br> To achieve this, development becomes an iterative process of creating code and verifying its operation. There are several steps in the development process: " Write/edit source code " Compile and link code to develop an executable for the target system " Flash executable onto a target system " Validate the application and debug the code " Repeat steps above if necessary More about Debugging Debugging utilizes one or more dedicated pins on the MCU to access built-in debugging hardware. The on-chip debugging hardware typically provides the ability to read and write memory, I/O and the CPU registers, and to start and stop program execution.<br><br> In addition, the target MCU generally contains a dedicated logic block that implements a few hardware breakpoints. While not as flexible and powerful as an in-circuit emulator, it can provide very transparent access to the MCU and target system. In addition, the connection between a host computer and the target MCU is facilitated by an inexpensive piece of hardware known as a wiggler.<br><br> In-Circuit Emulation An in-circuit emulator uses the actual target device in an expanded mode so that external circuitry can monitor both internal and external bus activity. Because some of the microcontroller 9s I/O ports are lost when placing the device in expanded mode, an emulator will typically utilize an FPGA to replace the lost ports. Additionally, the external circuitry typically provides a virtually unlimited number of complex hardware breakpoints and large amounts of bus trace memory.<br><br> In addition to source-level debugging, many emulators provide additional software analysis tools, such as code coverage and performance analysis. Pre-Silicon Emulation Before an announced MCU device is physically available, pre-silicon emulation can be used to mimic the behavior of that MCU with other hardware, usually a special purpose pre-silicon emulator system. The tool allows an entire system to be debugged before the silicon is available.<br><br> The emulator is typically plugged into a target system in place of the MCU, which allows a developer to test software in real time in a target system environment. www.freescale.com/automotive 4 Development Tools Simulation Even without silicon you can start development using Freescale 9s simulation targets. They allow developers to analyze how MCUs and their programs will act in an application environment.<br><br> The simulator shows the internal processor state and that of the outputs and allows input signals to be generated. Simulators can be the quickest way to debug and analyze problems. Understanding Run-Time Software Resources The embedded MCU development process is designed to create and validate binary executables that run on the embedded MCU once deployed.<br><br> This application run-time software can be developed from scratch using custom source code, from off-the-shelf prewritten source code or through a combination of both. Run-time software resources can provide you with a starting point for application development or, in some cases, with the total solution. Off-the-shelf prewritten software generally includes: " Operating systems , which manage CPU resources, I/O, communication and synchronization constructs, processes, threads and tasks.<br><br> " Device drivers, libraries and protocol stacks o Device drivers are target run-time software used to initialize and drive specific SOC or hardware board peripherals, such as Ethernet, USB and serial. o Libraries are run-time software components shipped as a package and intended for re-use. o Protocol stacks are communication protocols and other software that typically sit logically on the target OS.<br><br> They include software used to communicate between disparate processes (e.g. TIPC or CORBA) or software used to communicate with other devices, such as Ethernet or USB. Production Programming Options In cases where numerous MCUs need to be flashed with final code for mass production and duplication, developers have three options: " Stand-alone programmer allows you to connect directly to a board to program, test or debug an MCU.<br><br> " Gang programmer is a device with slots for programming several MCUs at once. " Factory programming is where a customer provides final code to an MCU supplier for code installation onto the MCUs during production.
