Using external clock to drive FPGA DE10-Nano

Hello,

Regarding the connection, I simply connected the AC15 pin from the DE2-115 to the AC24 pin on the DE10-Nano via a jumper, and used another jumper to connect the grounds. Anyway, although not needed, I attached a picture of the connection.

Regarding the monitoring, I tried to monitor the signal using the signal tap analyzer, but a "waiting for clock" message is displayed ( see the picture attached). When monitoring the signal coming out of the DE2, a 50 MHz signal is there (also attached). But, when trying to monitor the signal seen by the DE10, by assigning the value of the AC24 pin to another GPIO pin on the DE10 and monitoring the output on that pin, I only see noise.

The scope that I use to monitor the signal is Agilent DS06102A

Regards,
