xCONNECT on new XCore-XA chip

[atena]

Hi guys,

I have already some experience working with xCONNECT technology and bringing together different topologies of XMOS chips trough it.
I am trying now to connect the new XA chip over xCONNECT together to an L16, unsuccessfully so far. I figured out a platform file that makes sense for me and compiles but it fails when booting the application: xrun: First stage multi-node boot failed, please check XN file and Xmos link connectivity. I included attached such platform file in a txt file.

When I try to connect two XA chips, xTimeComposer says that this topology is just not possible for the moment.

Did anyone try to use xCONNECT on XA? Can you observe any error on my platform file? Do you have any idea how to buid up a platform file for such new topology?

Thanks a lot on advance!
Best:)

Hi,
Did the JTAG boot chain recognize and list the L8+L16 chaining successfully when you try to run "xrun -l"?

- Two XA chip topology is unsupported since the L8 core boots from the ARM boot. More information about boot is available @

I too would like to give a try on using xA and L16; I would post my experiment results once I ve tried this.
Thanks.

Hi srinie, thanks for your answer.

Indeed, [0:2] tiles were recognized, so JTAG chain was fine.

Got it. Thanks.

I too would like to give a try on using xA and L16; I would post my experiment results once I ve tried this.

It would be nice to see your outcome.

Best,
