Burning SDSU EEPROMS
It is recommended that extra EEPROMS, if needed, be copied straight from existing controllers. If this method is not chosen, the code will need to be downloaded from the CVS directory :
/home/dspdev/ccd/util/boot
for utility EEPROM code/home/dspdev/ccd/tim/boot
for timing EEPROM codeThe timing code will have a '.s' extension , the three utility files (one for each utility EEPROM) will have '.p0','p1','p2' extensions. If the utility board is held with the EEPROMs closest to the top edge, the chips are numbered from (left to right) : 1,2,3.
The Utility files can be burned straightforwardly into the EEPROM from location $0000.
With the Timing EEPROM, it is rather more complex :
Timing code from $0000 to $3fff : programmed into EEPROM address $0000 onwards
Timing code from $8000 to $bfff : programmed into EEPROM address $4000 onwards
