On power-up, the MSC8101 goes through a power-on reset (
jumping to an address vector (
signal = 1). This application note assumes the former, and that the address vector is located in Flash
memory. To run an application from Flash memory automatically after
programmed in Flash memory:
• Hard Reset Configuration Word (HRCW)
• Address table vector
• The application
The MSC8101ADS offers an option to allow the MSC8101 to load the HRCW from the on-board Altera
FPGA. When this option is selected, the HRCW need not be programmed in Flash memory. For
completeness however, this application note assumes that the HRCW is programmed in Flash memory.

Page 2: Background
Freescale Semiconductor, Inc. Flash Memory The following hardware is used in the procedure described in this application note: • Personal computer (PC). Runs CodeWarrior and the HyperTerminal application. • Parallel cable and parallel command converter. Connects the PC to the MSC8101ADS for use by the CodeWarrior debugger. -
Page 3: Generating An S-Record File
Freescale Semiconductor, Inc. Generating an S-record File Generating an S-record File The following steps generate an S-record file from an application that is later loaded into Flash memory. Create a project for the application. Using the menu option, create a project within the CodeWarrior directory and Project->Add Files include all the relevant files for the application. - Page 4 Freescale Semiconductor, Inc. Loading the S-record File Connect a serial cable between the COM port on the PC and the top RS-232 connector on the MSC8101ADS. This is the physical connection that allows the HyperTerminal application on the PC to communicate with the Flash loader application on the MSC8101ADS. Start up the flash programmer.

The address table starts at 0xFE000110. The MSC8101ADS maps this address to 0xFF800110. The following command loads a vector of 0xFF840000: -->hff840000 hff800110 program_word In this example, 0xFF840000 is the location where the address table starts in Flash memory. -

Application Example Edit the calc.h file for the corresponding crystal oscillator frequency on the MSC8101ADS (U18) and the baud rate used with the HyperTerminal application. Build the application if the calc.h file was modified. Start the HyperTerminal application on the PC and then run the Flash programmer application on the MSC8101ADS.

Page 18: Appendix F Example Hyperterminal Script File
Freescale Semiconductor, Inc. Running LEDblinker from Internal SRAM Appendix F Example HyperTerminal Script File The HRCW and address table example in this application note resides in sector 0 of Flash memory. The application resides in sector 1. Scripts can be used with HyperTerminal to program Flash memory. Erasing sectors are not included in the script because there is a delay when these commands are run, and HyperTerminal does not have a way to delay between sending lines out the next line. - Page 19 Freescale Semiconductor, Inc.
