How to tell DS-5 which chip to connect to?

I have a board with two Cyclone V devices on it and both have dual ARM processors in them. When I connect to my JTAG chain with DS-5, it happily connects to one of them but how do I now which one? An...

Hello,

So from the snapshots above, jtagconfig -n can view 2 FPGA devices, while DS-5 is showing one only.

For the schematics of our Cyclone V SoC development kit, there is a DIP switch that should be set correctly in order to make devices available on chain. In your case, its only DS-5 which cannot see the second FPGA.

Have you tried booting HPS on both boards? We need to make sure both HPS devices are working.

In the mean time, I will check with our internal team if there is a known issue regarding this.

Thanks
