ADAU1452 failed to save settings such as volume (volume starts at 0 on reboot)
I'm fighting over China ADAU142 treasure.
MP9, MP8, MP8 has adjusted the volume control button and push button volume control, but the problem is that the volume adjustment is not saved to zero.I turned off and turned on again.
IO->GPIO->input interface read/write is not working, and the master control port interface read/write is not working.
Press F7 to synchronize and read the Readback, but not necessarily stored in the value is not stored.Why do you tell me?
This DSP board photos are also attached to this DSP board photos.
( It's not my original word, so please understand if the sentence is weird :) )

Hello NSteven,
Please try this attached project. I have tested this here and it works as expected. It holds the level (volume) at the time power is removed and starts from the same level (previous) when powered up.

Well, I tried it, but it's still the same.
But when I did "Read All Registers", error in DM0 Bank 3 shows red, is this the reason?
I'll attach a file that has been modified to fit "Read All Registers" and my codec.
(It also uploads a video that reproduces the symptoms.)
Hello NSteven,
Your project does work fine for me. So, we have to look at the hardware schematic between the DSP and the EEPROM. The schematic that you attached was not clear enough. So, I couldn't find the connections clearly. could you please reupload it with better quality?
Regards,
Harish

Hi, this is the best I can get
Hello NSteven,
Unfortunately the PDF files are just not readable.
Did you find the problem?
Perhaps send a friend request and then send me a PM with the PDF files in the message. That might work better.
