Audio Decoder Communication DE2-115

[Lululukas]

Hello,

I'm trying to convert a design from the Cyclone 2 to the Cyclone 4.

The design communicates with the audio decoder and there is my problem.

The audio decoder communicates with I2C and there are no problems with Cyclone 2.

Both boards have the same audio decoder.

I tried another design from AhmadGon

https://github.com/AhmadGon/WM8731-Audio-CODEC

When i load his design on the board it works and when i load my design on the board after his, my design also works.

So i thought the audio decoder isnt properly intialized in my design. I copied the init from AhmadGon but it didnt work. Now i'm clueless what else he's doing different than i am.

Hi Lukas,

Apologize for taking up your time on this, please understand that I really want to help you in this issue.

Unfortunately based on discussion with internal team, your description of the FPGA product cyclone 2 and cyclone 4 are considered Intel legacy product.

We no longer have support for this legacy product.

For the design you use from AhmadGon, you may need to reach out to him directly as he is the developer of the design.

Hope this answers your question.

Thank you.
