Hi, we have made an application using ADAU1701.

We have loaded the program into the I2C eeprom (24lc256).

It is very small and simple.

But it seems to get stuck when booting. See the attached scope shot.

For me it looks like it stops reading the eeprom data as it receives a 0x00!? Can that be the reason?

The data we have stored and verified in the eeprom is:

Don't get confused about the 0x50+Write address.. It is the same as 0xa0 and 0x50+Read is the same as 0xa1

Any suggestions what's wrong here?

It is solved. I used the E2prom program to program the I2C eeprom.

So i was loading the parameters and not the program into the EEprom
