Using ADau1452minz and SigmaStudio 3.11 build 2 rev 1396.

The adau1452 is amazing, and SigmaStudio is a very easy to use GUI.

My project is sounding great!!!!!!!

However, I have been unsuccessful at downloading to the eeprom

When I press "Download File to E2prom", then "OK". A window pops up showing download in progress, then completes.

But, When I flip S2 to enable boot from E2prom, then press reset, it does not load my program, it apparently loads the default program that came in the eeprom. D6 and D7 flash on and off (I did not program that). To further my investigation, I see no activity (with scope) on SS_M or SCLK_M when I repeated the download procedure. The only point that I did see activity is when I place S2 in enable then press reset.

It appears that it will read from eeprom but not right to it.

What am I doing wrong?

Also when I copy "capture window" into "sequence window" then export sequence.hex file, (2) .hex files are created.

One is FilenameIC_1.hex the other is FilenameIC_2.hex

Which of these should I download, or is it something else.

Thanks for any help.

Jim

Hello James,

It seems like you are close, but I wonder if the sequence you are following is incorrect? I have no issues writing a program to the serial flash.

Refer to the eval board guide page 17.

You may need to instead execute the command "Write Latest Compilation Through DSP" by right-clicking the ADAU1452 IC.

This will automatically grab the correct .HEX file for you and you do not have to use the EPROM utility to download the file.

Wasn't clicking on ic1, just in open space. THANKS.
