Hi Kristoffer,
I have attached the schematics the schematics of the AIC34 and CC8531 integrated for 4 microphone operation.
The Problem with present configuration is that.
1. I am able to program the CC8531 through purepath configurator.
2. As soon as the programming is completed, the network status LED starts to blink(Alone LED pattern).
3. In both Master and Slave CSN button is clicked to pair after this - Active LED pattern should occur, but instead we are receiving a different LED pattern, which is shown in the attachment image.
Steps taken so far,
1. Programmed CC8531 with "DSP" selected as CODEC and checked the LED and pairing - Test success ( Active LED indication occurs.
2. Programmed CC8531 with AIC34 selected as CODEC and this time integrated AIC34DK through I2C lines instead of our on board AIC34 IC and checked the LED status while pairing - Test success ( Active LED indication occurs )
Ruled out so far,
1. with the above steps we have confirmed that CC8531 is not the problem creator.
2. with oscilloscope reading we could find that the MCLK, BCLK and WCLK signals are not as espected.
3. RESET Line seems to be okay
Problem:
1. Unexpected LED indication.
2. we have removed and replaced the AIC34 asic for almost 8 times, but same unexpected LED indication !
Solution required to solve the above issues.
Hope the issues were clear and understandable now :)
expecting your support towards this issue.
Thanks & regards,
