Chaining XK-1As and AVB reference end point

Post by ashleyb »

Hi All,
I'm trying to chain together 2 XK-1As and an AVB reference board via the XSYS connectors. The setup I have is XTAG2->XK-1A->XK-1A->AVB. I want the setup to boot from the SPI flash on AVB board. I created a custom XN file for this setup, the code compiles but I can't get it to run. At the moment it is just a copy of the app_17221_device from the sw_avb repository with the xlog server moved to the XK-1 nearest the XTAG2.

Can anyone see anything wrong with my XN file which would cause this?

Make sure you are using the 'c' rev of the XK1 as versions before that have incompatible SYS extension connectors. Otherwise you will need to put an adaptor in between the last XK1 and the AVB board to correct the Xmos Link connections.

some more info here :
XK-1 Adapter Dongle
XSYS XLINK Corrector(not tested)

He's talking about XK-1A's so that shouldn't be a problem.

The XK-1A's are not bootable over XMOS Link (The XSYS headers are connected to link C and D; the XS1-L can only boot from link B).

Thanks guys. I guess that means I am going to have to program each of them individually and then let them boot and connect to each other.

Is there any example code of showing how to setup links across devices which have individually booted?
