ADAU1401: make programming persistent

vds · 29th August 2020, 11:56 PM

Hello I'm trying to program one of the cheap ADAU1401 boards from Aliexpress, Everything seems to work fine,but when i shutdown the board it resets to the original programming.
Are there any way to save the programming on the board?
P.S.: I already tried to connect the WP pin to ground but it sorted no effects.

First: I assume you are doing the "Link Compile Download" command and get an "Active Downloaded" response in the lower right corner of the status bar.

Are you then selecting the "Hardware Configuration" tab, right-clicking on the ADAU1401 control and selecting "Write Latest Compilation to E2PROM"?

What i was missing was adding the E2PROM block and then writing the last compilation.
Finally I was able to make it working.
Thanks for your help.

Are you happy with the DSP board?
