Re: Sporadic "crosstalk" from I2C into TDM mic input when ports and SW on the same slice or connector
Once more than five cores in a tile are busy then they are allocated less time, so that might be responsible. Alternatively you might really have some interference (or both!). You could distinguish between them by adding a task that uses processor time but does not have any side effects that could g...

Re: how to trigger an event/select on buffered port output ?
Could you use xC to handle the timestamp directly on the output? I don't know if it would be a bit more efficient, but probably more readable.
See section 6.8 in the XMOS programming guide.

Re: SPI Flash Partition Table
I would have thought the partitions are packed, so the position of each one (apart from the first) is variable depending on the partition size. Can you inspect the fl_BootImageInfo structure to determine how big a partition is? It would then be just a matter of adding on the size of each partition t...

Re: Technical Guide to C for xcore - new YouTube tutorial
True enough Ross - I hadn't realised but the YouTube channel has the same video from Sept 21. Apologies if I misled anyone. I agree with fabriceo: interfaces are still a blind spot in the new C-style development path. Many of the existing libraries use interfaces and it's still not clear (to me anyw...

Re: Dual issue mode / 64 bit memory alignment
1) There are some threads here on the forum claiming that for dual issue mode, the memory of arrays and structs must be aligned to 64 bit otherwise some unpredictable things happen. Is this really true? I have not found this restriction anywhere in the official XMOS documents, yet. And I think it w...
