jpeyron Posted February 15, 2019 Share Posted February 15, 2019 Hi @aeon20, In the hardware manage you select 1)open target, 2) select auto connect 3) select program device. Please attach screen shots of what you are seeing on these steps. Also your screen shot of the hardware manager show that it sees the Nexys A7. I have attached a screen shot of how the hardware manager looks when there is not board attached. thank you, Jon Link to comment Share on other sites More sharing options...

jpeyron Posted February 15, 2019 Share Posted February 15, 2019 Hi @aeon20, Here is a forum thread with a similar situation where the issue was the emulated USB controller. They needed to switch to Q35/nec-xhci. thank you, Link to comment Share on other sites More sharing options...

aeon20 Posted February 20, 2019 Author Share Posted February 20, 2019 I can also add that I've now tried a different physical computer with a fresh Debian 9.7 install. I get the same result: "No devices detected on target". I'm not using an emulated USB controller. The board "partially" shows up though, just as before (same screenshot as above, but identical results, just didn't bother making a new screenshot when there is nothing new): Link to comment Share on other sites More sharing options...

Here is the link i was referring to. thank you, Jon I don't believe I have the same issue as this other person. He is able to initialize the scan chain with the init and -d argument to djtgcfg. I am not. I get: # djtgcfg init -d NexysA7 Initializing scan chain... ERROR: failed to initialize scan chain Moreover, this is not a virtual machine, the USB controller is real and not emulated. This machine has two NVIDIA MCP51 USB controllers. One controller is running on the ohci-pci kernel driver, the other on ehci-pci. Should I try to force the USB controllers to use xhci? If enforcing xhci drivers on the USB controllers is required to make Vivado work, it would probably be a good idea to inform the developers of this fact. I'm simply running a 100% stock Debian install on a non-VM computer. If this is indeed the issue I can imagine many others also experience the same but simply give up. This is far from easy. I am still stuck at "No device" in Vivado. Link to comment Share on other sites More sharing options...
