contents flash memory uploaded disk file This useful saving current microcode before device reprogrammed making duplicate existing flash memory. output file Intellec 8/MDS format. This file later used reprogram device input file verify operation. There difference between output file upload function output file from compiler/linker. Intellec 8/MDS formatted file made independent data records, each contained single line text, each specifying starting address. Therefore, there requirement order data file. compiler/linker outputs data records nonsequential order eliminates unused areas data. upload flash memory function outputs data sequential fashion starting with address 0x0000 ending with highest address used. Therefore, upload output cannot byte-for-byte compared with compiler/linker output. However, files either sequential type nonsequential type used input files program verify functions. upload flash memory disk file, click Upload button. Click Browse. button specify output file name select existing file overwrite shown Figure 7-10. start upload operation, click Execute.

Using Flash Memory Utilities
reprogram operation been performed previously (since last time restarted), message Figure 7-11 appears. this case, upload operation allowed until flash memory utilities exited restarted. Although microcode been loaded into flash memory, microcode still executing from RAM. reprogram operation been performed, progress indicator indicates number bytes read from flash memory written output file shown Figure 7-12. number bytes contained code flash memory inserted into code compiler/linker extracted Upload function. After progress indicator disappears, status indicator says Ready completion message displayed, shown Figure 7-13.

exit flash memory utilities, perform following steps: Move jumper Normal position (marked Press reset button. This returns normal operating state initiates power-up initialization sequence after which should output proper video LEDs should flash (the heartbeat). Finally, click Close button Configure Flash Memory dialog terminate WinVCC. steps done correctly, WinVCC terminates. steps done correctly, message shown Figure 7-14 appears. Follow instructions then click Continue terminate WinVCC. power turned before attempt close Configure Flash Memory dialog box, serial timeout dialog message appears, shown Figure page 2-4. Click Exit Program button terminate WinVCC.
