That's how it works, there is no FLASH on board, you have to send code from a micro at power on OR you can self boot with a serial FLASH.

In the data sheet.

Page 25 about about startup

Page 45 has details of self boot from an external memory.

Page 85 about programming.

Hello Harishsharma,

Thanks pbthesp for the response. You are exactly right.

Here is the user guide for the eval board.

EVAL-ADAU1467Z (Rev. 0) (analog.com)

On page 28 it explains how to program the EEPROM for selfboot.

Hello DaveThib,

Is there any option to add flash memory at the place of eeprom.

Hello harishsharma,

Yes, several customers have used Flash instead. There are a few details to choosing one that works. There are some posts on the forum but it also gives some details in the datasheet.
