This is the first time that I post here. I hope that I'm doing well.
We have a new design where we use a 410-251-B board in order to interface with JTAG a Zynq 7000 SoC. I used the following configuration suggested by Digilent:
With an oscilloscope I see the GPIO2 output (yellow) and I detect an amazing waveform. If the equipment is powered I see a stable signal, but if I select "Autoconnect" in Vivado I have the next signal:
Blue signal is the input of PS_SRST_B.
When a try download a bitfile, I have detected that GPIO2 waveform varies and sometimes this process is aborted (when PS_SRST_B have a low level). I show you two cases of this:
abnormal signal in GPIO2 in 410-251-B board

Hi all,

1.
2.
Do you have any idea about what is happening?
Thanks in advance.
