Hello.
I'm a student working on a project with the MicroZed board, along with my partner. We are using Vivado 2015.4, Xilinix SDK 2015.4, and a Digilent USB-JTAG Programming Cable (we don't have a Platform Cable USB).
In the beginning, we were able to program the device, in Vivado or SDK, using the hardware manager "Auto Connect" option. Starting some time ago, we can no longer do that: When trying to program the device using the Auto Connect mode, Vivado gets stuck, and SDK gives the massage: "Error while launching program: fpga initialization failed".
We have to use the hardware manager "Open New Target" option, and to lower the JTAG Clock Frequency to 3000000Hz or less.
Is this a problem with the MicroZed JTAG connection? Can it be fixed?
Thank you very much!
P.S.
We have tried using different USB or JTAG cable. We also tried uninstalling and reinstalling some drivers, as described here:
We are both pretty novice, so if possible please use simple words and not too technical language. Thank you!
