CHAPTER 11 FIRMWARE UPGRADE 11 In this chapter: • This chapter describes an interface for programming (loading) firmware into the Copernicus GPS receiver. The interface can be used to develop a tool to upgrade firmware in the field. Sample source code of a tool for Microsoft® Windows is available to demonstrate implementation of the interface described in this document. • Software Architecture • Boot Monitor • Firmware Binary File Format • Firmware Loading Procedure • Monitor Interface Protocol • FlashLoader Tool Reference Guide This chapter describes an interface for programming (loading) firmware into the Copernicus GPS receiver. The interface can be used to develop a tool to upgrade firmware in the field. Sample source code of a tool for Microsoft® Windows is available to demonstrate implementation of the interface described in this document. The information contained in this chapter is applicable only to the Copernicus GPS receiver developed by the Advanced Devices group of <strong>Trimble</strong> Navigation Ltd. It may not be relevant to other products. Copernicus GPS Receiver 105
11 FIRMWARE UPGRADE Software Architecture The Flash memory chip of the GPS receiver is divided into several functional sections. The Boot ROM section is loaded during production and cannot be changed or erased without special packets with password protection. The User Data section is maintained by the application. The Copernicus GPS Receiver Firmware section holds the main software application, and can be erased and loaded with a newer version through the GPS receiver’s serial port. Table 11.1 Functional Software Components and Memory Map Word Address 0x3FC000 – 0x3FFFFF 0x3F8000 – 0x3FBFFF 0x3E0000 – 0x3F7FFF 0x360000 – 0x3DFFFF 0x300000 – 0x35FFFF Software Component/Section Boot ROM User Data Copernicus GPS Firmware Boot Monitor The boot monitor module is a part of the Boot ROM section. It provides facilities to perform checksum verification and RAM tests, and to read/write data from/to a specified location in RAM or Flash, thus allowing the user to update the firmware. The GPS receiver will enter the boot monitor mode if either of the following conditions occurs: • Application firmware checksum verification failed at power-up; • RAM test failed at power-up; • A special protocol packet is issued by the user. Once the system is in the monitor mode, a special Monitor protocol is used to communicate with the Copernicus GPS Receiver (here after referred as the Target). The necessary details about this protocol are presented in Appendix A. To return from the monitor to the normal GPS operating mode (i.e. execute the application firmware), either • Cycle the main power or • Toggle the reset pin, or • Send a “Restart Target” packet described on page 115. The default settings for the Copernicus GPS receiver’s serial ports in the monitor mode are: • Serial port A: 38400 baud, 8 data bits, 1 stop bit, and no parity • Serial port B: 4800 baud, 8 data bits, 1 stop bit, and no parity 106 Copernicus GPS Receiver
