Replacing the PassThru in code in I2C EEPROM with user code {56720 EVM}

Hi Guys

I've written and tested my DSP assy code on the 56720 EVM Dev board.

Does anyone have any pointer to documentation that will show me how to overwrite the PassThru code on the EEPROMS, with my own code, to make my Dev board run my program in stand alone mode?

Thanks

Hi Pete,

I did EEPROM writing programs for various DSP563xx derivatives in the past but never for the '72x. Maybe I will have a try on the '725 if it will be rquired.

Have a look at the SoundBite SOUNDBITE_ASSY_TEMPLATE program, see:

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=SYMP_SOUNDBITE&fpsp=1&tabign_Tools_Tab

You will need to register at the Freescale website to have access.

The code example is done for the '371 but should be portable to the '72x (easily).

The module sb_eeprogram.asm does exactly what you want and in contrast to my own code it is fairly documented.

The good news is that the '72x daupherboards use the same M24M01 I2C EEPROM chips and the '72x architecture is very close to the '371.

Best regards

Christian
