    Hi,

    thanks for the reply , problem is solved, I sent the 313MHZ signal instead of 313KHZ, the GPIO pin with 3.3 LVTTL std dont have such high bandwidth.

    When I set to 313KHZ the result is good.

Hi CAlex,


May I know if using the same pin as normal GPIO and is triggered by HPS, does it shows a normal digital signal?

Can try to loan with other pin as well to see if the same problem occured.


Thanks.

Regards,

Aik Eu
