bootloader 1-1 chapter 1 bootloader 1.1 serial bootloader the serial bootloader has been developed to load and run a proprietary user application presented as an s-record file into the program and data memory. the serial bootloader is located in the dedicated program memory region, called boot flash (see section 1.1.5 ). the serial bootloader supports the simplest serial protocol, so any standard serial terminal program can be used on the host pc. the serial bootloader application reads the s-record file of a user application (for example, generated by codewarrior) via serial interface, parses this s-record file, and stores needed data in program and data flash memory. when the processing of the s-record file is finished, the bootloader launches the loaded application. if any error occurs while loading the s-record file, the bootloader outputs an error message with an error number via the serial line and resets the processor. see figure 1-1 . figure 1-1. programming flash on a 56f8xx device program flash data flash bootloader running sci s-record s-record f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

bootloader 1-3 1.1.1.1 step 1: power-up/reset the dsp56800 core specifies two reset vectors: hardware reset and cop reset (normally located at addresses 0x0 and 0x2, respectively). the hardware reset vector identifies the address that the processor accesses once it recognizes a power-up or power reset. when the dsp56f80x bootloader is present, it controls this address by placing a bootloader entry point into the hardware reset vector location. 1.1.1.2 step 2: transition to applications entry point when the dsp56f80x bootloader completes its execution, it transfers control to the users application by performing a jsr instruction to an address specified in memory location 0x0081. the address of this routine is placed into the 0x0081 location via the interrupt vector table located in the vector.c configuration file. 1.1.1.3 step 3: start-up code execution of archstart() begins. 1.1.2 bootloader version number the most current version of the bootloader is 1.3. 1.1.3 files the serial bootloader application includes the following files: ? ..\applications\serial_bootloader\bootloader.mcp, project file ? ..\applications\serial_bootloader\bootloader.c, main program ? ..\applications\serial_bootloader\bootloader.h, header file with common parameters ? ..\applications\serial_bootloader\com.c, communication module ? ..\applications\serial_bootloader\com.h, header for communication module ? ..\applications\serial_bootloader\sparser.c, s-record format parser module ? ..\applications\serial_bootloader\sparser.h, header for s-record parser module ? ..\applications\serial_bootloader\prog.c, flash programming module ? ..\applications\serial_bootloader\prog.h, header for flash programming module ? ..\applications\serial_bootloader\bootstart.c, startup module ? ..\applications\serial_bootloader\constdata.asm, description of strings data ? ..\applications\serial_bootloader\resetvector.asm, reset and cop reset interrupt vectors description ? ..\applications\serial_bootloader\flashprog.c, flash programming subsystem ? ..\applications\serial_bootloader\flashprog.h, flash programming subsystem ? ..\applications\serial_bootloader\targetdirectives, board name definition f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

bootloader 1-11 1.1.8 requirements for a loaded program if the application is loaded via the bootloader, it must meet the following requirements: ? particular start address for application - the entry point for the loaded application must be located at address 0x0080 in program memory; i.e., immediately after the interrupt table ? application cop vector - to use cop interrupt vector in an application loaded via bootloader, the entry point for the cop isr must be located at address 0x0082 in program memory ? application start delay variable must be set at address 0x0085 in program flash ? restricted resources use - the application cannot occupy reset and cop interrupt vectors, and cannot place code into boot flash memory area. there is no way to place any initialized variable from the application into internal data ram while loading. this memory area is used by bootloader. all data from the s-record file that address to the restricted area will be ignored. external program memory is unavailable while loading the application because the bootloader is performed in dsp mode 0a memory map. the bootloader provides a configuration variable (bsp_bootloader_delay) can be defined in the bootloaders appconfig.h file that determines the applications start delay time-out. possible values of bsp_bootloader_delay: if there is no bsp_bootloader_delay set in the appconfig.h file, the default value for time-out is 30 seconds. 0 disable the bootloader, start the application immediately. after loading the application with this setting, there are only two ways to re-enter bootloader: ? reload the bootloader from metrowerks codewarrior into boot flash ? reprogram the value of the start delay variable located at address 0x0083 in the program flash to zero value (0x0000) in the loaded application 0 - 254 set waiting time for the start of the s-record file for 0-255 seconds before the start of a previously-loaded application 255 set waiting time to infinity. after reset, the bootloader waits for the s-record file without counting down any time-out f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
