Re: XN file for dual XCORE-200-EXPLORER setup
I think there are a few things wrong. You have declared two flash memories but your second node is set to boot from a link, also the tile numbers within each package are local, it's the references that are global. Here's a working XN file from an old project using two xCORE-200 explorer kits. I don'...

Re: Sneaky problem with libusb & audio on transfer to host
Re -O3 vs -O2, I seem to remember reading somewhere that the -O3 switch can sometimes be buggy. However I don't have any hard evidence to hand and I have had -O3 code working reliably (e.g. in the ethernet library).

Re: Sneaky problem with libusb & audio on transfer to host
I don't have any detailed knowledge of xmos USB audio, so just a few general points. 1) Is the device clock synchronised in some way with the USB? In which case, if there were problems with the source clock would that affect the reliability? For example, have you tried it with more than one PC? Are ...

Re: Looking for advice on mixing ARM and xmos
Hi, thanks for your message. I don't mean there is no in-system debug for the ARM, simply that access to the interface won't be available on the outside of the equipment (unless someone knows how to make the xTAG work with arm devices). I need a fast-ish interface for periodic real-time data transfe...

Re: xCORE ARRAY MICROPHONE board kernel source code and how to realize parallel processing
Just look at the relevant data sheets or architecture documents. There is a lot of information available.

Re: typedef cannot be used on pointers
You haven't said what kind of code you are trying to compile.
Assuming you mean xc, typedef void * unsafe aatest; will compile.

Re: xCORE ARRAY MICROPHONE board kernel source code and how to realize parallel processing
The xcore.ai (or XS3) also provides parallel processing through hardware. In addition, there is a FreeRTOS port coming in the sdk.

Looking for advice on mixing ARM and xmos
Looks like I will need to use an ARM device in a new project together with xmos devices. I'll need to provide for in-system reprogramming, and I'm planning to provide an xTAG in the product with its USB port exposed. I'm hoping the QSPI flash for the xmos subsystem to also contain an image for the A...

Re: xCORE ARRAY MICROPHONE board kernel source code and how to realize parallel processing
Re your second question, the parallel processing is provided in hardware. There is a lot of information on the xmos web site.
