I've already posted this topic on zedboard.org but I think it's relevant to repost it here.
I'm currently developping on a ZedBoard (Rev C) with a working design (tested). However, I haven't been able to launch any program (Hello World...) for some days and I get everytime the same error:
Blue LED is lighting after the FPGA is programmed but it seems the programming tool can't view any ARM device. I tried with the XDM command "connect arm hw" and I obtained the following answer:
JTAG chain configuration
Device ID Code IR Length Part Name
1 03727093 6 xc7z020
Could not find a ARM device on the board. Please check if the target is in:
1. Split JTAG mode - No operations are possible with ARM DAP
2. Non Jtag bootmode - Bootrom may need time to enable DAP. Please try again
Here is my configuration:
J17: USB programmation
JP7-JP11 : to GND (JTAG config)
everything else opened
I'm working with Vivado 2015.1 under Windows 8.1 (but also tested with Win7)
Do you know, guys, what is this related to ? I've already searched on forums but the answers don't work for me.
Thank you !

It is not detecting the fpga on the board. You said that this issue appeared recently.
Can you give some more depth on what changes were done from the time it was working properly?

@siktap : I think it's detecting the fpga but not the ARMs: I can download a bitstream and run a softcore Microblaze on it.
Not much changes were done. On the last Thursday, I tested a project with an adder as a slave AXI peripheral with UART communication and on Friday the same design didn't work... I had a lot a driver problems before Thursday but now it's working and I tested it with an other computer.
I really take care of the board (I avoid ESD, I switch off the board before changing any jumper ...). That's why I really don't understand the problem.
@smarell : I tested with other cables but I got the same result. I will test on an other board as soon as I can.
Thanks for helping me.
