XK-1 and XScope

[gron]

Trying to run xscope on an XK-1 board with the new dev tools.
I added the following lines to the XN files:

<Link Encoding="2wire" Delays="4,4" Flags="SOD">
<LinkEndpoint NodeId="0" Link="X0LC"/>
<LinkEndpoint RoutingId="0x8000" Chanend="1"/>
</Link>

and tried different variations of Link="X0LC" item (tried A-B).
In all cases I get the:
xrun: Program received signal ET_ILLEGAL_RESOURCE, Resource not valid.
[Switching to stdcore[0] hwthread 2]

Error.

Any clues? I'm at my wits end....

Hi Gron,

The XK-1 does not support XScope functionality, due to the XSYS X-Link being wired in reverse. Please use the UART XScope functionality for this board.

Kind Regards,
Corin

Which boards do support XScope functionality?

[XMatt]

Currently,

- Low cost AVB board
- Multichannel USB 2.0 Audio board
- Motor control platform

All others are supported with the fall back to UART.

I would anticipate that it will be present on all new designs unless there is a good reason not to include it.

- Low cost AVB board

$349.00

- Multichannel USB 2.0 Audio board

$349.00

- Motor control platform

It'd be great if there were some way (without UART fall back) to try out the new XScope feature on more "cheap and cheerful" development boards (all of the ones listed are under reference designs). I'll admit I'm new to the world of XMOS, so this may be a silly question, but is there no way to use any of the pins on the existing development boards that are opened up to IDC headers?

Can I just clarify the XK1 support.

I have an older XK1 and also what I assume was a newer version given it was shipped after you issued the new design files. Is the newer version corrected with the power monitor changes and the XSYS X-Link fixed?

As I said I expect all new development boards to support the xlink xscope feature if it makes sense. Currently the reference designs are the only boards supporting it that you can buy. There is no reason why you cannot modify an existing board if you like, this has certainly been done with the L1 Audio and IPOD dock platforms which dont support the link to IDC connection out of the box.

As far as the XK-1 is concerned if you swap the links around the functionality does work. All current XK-1's that have been shipped have the links swapped over.

Thanks XMatt

Can I also clarify that even the XK1 "New Design" schematic is incorrect, its important because I was following it as part of another design?

Sorry I have another question, if the link connections are swapped how come you can still daisy chain XK1s, surely the links would not work in that case?
:?

In fact from memory I think the XK1 new design was the only reference L1 design that included pinouts for XSYS X-Link receptor, so I would imagine many others also used this design to refer to when designing L1 boards.

Anyone else checked their XSYS X-Link receptor designs on their own boards?

Update I checked my L1 designs, definitely incorrect..
