Parameter update block on ADAU1787
I am using the ADAU board to prototype a low-latency filtering solution. My goal is to feed filter parameters via the I2S interface and insert them into a FIR block using a Parameter Update block. However at present even the simplest application of parameter update does not work.
Namely, I cannot set a value of the DC source. The minimal project showing the problem is attached.
A very similar schema on ADAU1467 works according to my expectations.
I saw another post with this issue but without any conclusive answers.
Am I doing something wrong, or is this feature not ready yet?

Hello pawelld,
We are looking into this. I was able to verify the issue on our eval boards. We will let you know if we find a work-around.

Dear Dave,
Were you able to figure something out. I was able to circumvent the problem for a while by implementing a FIR filter with delays and multiplications (just 4 taps) and validate the idea. But now we need more taps and our current workaround consumes too many cycles.
We really need this parameter update to work.
Best regards,
Pawel
