About This Book This guide provides a detailed description of Freescales Embedded Bootloader and describes how to port Freescales Embedded Bootloader to a specific PCB/target.. The Embedded Bootloader is intended for use with the IEEE® 802.15.4 evaluation kits (EVK). However, it is possible to upload applications with the Embedded Bootloader in the development phase, but the Embedded Bootloader will not provide any debug functions. The Embedded Bootloader provides an easy and inexpensi

Chapter 1 Embedded Bootloader Description The Embedded Bootloader is intended for use with the IEEE® 802.15.4 evaluation kits (EVK). However, it is possible to upload applications with the Embedded Bootloader in the development phase, but the Embedded Bootloader will not provide any debug functions. The Embedded Bootloader provides an easy and inexpensive way to upload new firmware and eliminate the requirements for expensive debug/development tools. The only requirement is a standard PC

1.2 Features The following features are supported: • Upload firmware (802.15.4/Zigbee application) in Motorola S19 record format through UART/USB. The S1 data record length must be set to 32 bytes • Auto-Detection of the PC communication interface (see Section 1.1.1, Ported Targets). • Initialize memory including stack of uploaded firmware • Initialize the system clock. Self clocked mode and MC13192 clock setup. Power save mode supported • Run time update/change of the NVM NOTE See

Chapter 2 Using the Embedded Bootloader This chapter describes the Embedded Bootloader functionality. A detailed description of the functions briefly mentioned in this chapter can be found in Chapter 7. 2.1 Upload Firmware The Embedded Bootloader can be used in different system configurations depending on the PCB and the application. The application should have a user interface feature that makes it possible for the application to call the Enable_Download_Firmware() function: The appli

2.3 System Bus Frequency The MC908HCS08GB60/GT60 starts in 4 MHz self clocked mode. The init code changes this to 8 MHz after a few instructions from reset. If NVM data is found, the system clock (MC908HCS08GB60/GT60 ICG module and MC13192 CLKO) and other options are setup as specified by the uploaded application. See the Freescale 802.15.4 MAC/PHY Software Reference Manual, 802154MPSRM/D, for more details. If no NVM data can be found, the following (safe mode boot) values are used: •
