Updated self-boot EEPROM image generation / download by BrettG
Up until version 3.1.9 of SigmaStudio, there were some issues with the ADAU1442 self-boot functionality. These will be fixed in the next SigmaStudio release, which will probably be available this month or next. This post has a brief description of the updated functionality, which will be available for all SigmaDSP processors that use self-boot.
Method 1 : Automated Generation / Download
In the hardware configuration tab, add an E2Prom IC to the USBi Interface.

Create a simple project, like this one that outputs a 1 kHz test tone to the serial port.

Right click the ADAU144x and select "Write Latest Compilation to E2PROM". Then self-boot the system by resetting the SigmaDSP while holding its SELFBOOT pin high.

Method 2 : Manual Generation / Download
Alternatively, you can use the capture window. After link-compile-downloading, click the top line of the capture window and then shift-click the bottom line to select all lines.

Under "Save as type," select the new EEPROM(ascii) (*.hex) format to generate a .hex image file. This lets you save many different image files for different projects.
