Re: Why do I get Cannot load image, XCore 0 is not enabled?

3. No clock is being supplied to the device; or the clock frequency supplied to the device is unsuitable for the selected PLL multiplier. The PLL multiplier is set using the MODE pins and should be configured so that the XCore boots up at or below its maximum frequency. Further details on the MODE ...

sw_usb_audio_6.15: Audio output just stops randomly

We've been seeing audio output (only output) stopping randomly. It happens at seemingly random times. This is a custom board, based off the xCORE Microphone array XP-USB-MIC-UF216 array. I saw in another post that somebody else was having the same problem (https://www.xcore.com/viewtopic.php?f=37&am...

Re: XUF208 TDM8 USB Audio

So I now have consistent activity on the TDM lines (an issue with signed-ness on the output stream appears to exist also, but I'm sure this is separate). As I figured this was likely going to be an issue in the XUD_Manager - or at least some sort of configuration I missed - I solved my issue by rep...

Re: the problem is the output signal is shutdown, waiting help,thanks

We have exactly this same problem. It's a custom board, but the XUD_GetData_Select stops getting called, kind of randomly. I cannot figure out why. Did you ever resolve the problem? BTW, this has nothing to do with I2C. It's way back in the XUD layer -- XUD itself seems to stop calling XUD_GetData_S...

Re: Why are the mics on xCORE ARRAY MICROPHONE 1.8v?

Hi Caleb. From the downloaded hardware manual, the schematic shows the array of Akustica AKU441 microphones being powered by +3v3. Do you have a different kit? Vaguely recall that at least one of the XMOS kits was fitted with the Infineon SMD microphones but not sure of their normal operation volta...

Why are the mics on xCORE ARRAY MICROPHONE 1.8v?

Hi there,
Does anybody know why the microphones on the xCORE ARRAY MICROPHONE board (XK-USB-MIC-UF216) are driven at 1.8 volts? The mic spec itself allows up to 3.6V. Is it to come in under some power budget maybe?

Thanks,
-Caleb

Re: xCORE-200 MC Audio: TDM channels out of sequence on record

Hi, I'm trying to deal with the same issue now. I'm wondering if this was solved? Thanks! I'm sure it was solved... Now I'm trying to recall how it was solved, and having a hard time remembering. I have been off that board for quite some time, so haven't been thinking about it. I think my hack was ...

Download links not working

Hi there,
I'm trying to download "xCORE-200 Multichannel Audio Platform Altium files" from the page http://www.xmos.com/jp/support/boards?product=18334, and I get "too many redirects".

Is that just me, or does everyone have that problem?

Thanks,
