Re: New XMOS chips??!

Awesome! A XU part in a TQ package. Maybe I don't need to do a BGA after all.

More memory ok.

Any word on when parts will be available? XU208-128-TQ64?

Are existing parts going to be available for a while, or do these take over?

Thanks.

Additional information learned about Flash protection

The XMOS xFlash manual did not answer all my questions regarding write protecting flash devices. So maybe this can help some. If I got something wrong here, speak up. 1 - Only sector protected devices are supported by xFlash for protection. Very few devices offer this. The Atmel AT25DF041A does, mos...

Re: xFlash taking forever to program

Thanks for the reply. Tested the --save-temps. See below: xFlashTemps.PNG Files were generated quickly, so probably not a build issue. Here's the command window: xFlashExample.PNG xFlash gets to the last xmap warning in about 5 seconds. Ok. Takes several minutes to get from that last warning to the ...

Re: Link priority and the pause control token

I implemented a control token handler to arbitrate multiple packets thru a single link. Which control token is sent at the beginning of the packet directs the traffic to the correct routine or via a intra-tile channel end to another core. Sending a pause token is being "depreciated" if I r...

Re: iir filter implementation

Calling the same routine on multiple cores or tiles is not an issue. It will get replicated as needed, in the case of different tiles. One issue to deal with though, is setting breakpoints inside a common routine. Setting a breakpoint has an issue inside a common routine, since it can get triggered ...

Re: XS1-U8A-64-FB96 Are NC pins truely not connected?

Thanks all.

Maybe a better name for those pads may be "Test" or "Don't Connect" ;)
