Does 120 ohm pull up with LED indication work for CONF_DONE for 5AGXMB1 FPGA?

As per datasheet, 10K is recommended to pull up for CONF_DONE. Attached the circuit followed in our product.

    Hi SKacc,

    Thank you for contacting Intel community.

    Intel recommended 10k to pull up for CONF_DONE. 120 ohm can be use, but Intel will not be responsible if it is not working for the device. Hence it is better to follow Intel's guidelines.

    Thank you.

    Regards,

    Hi Srikanth Kacchu,

    Usually we used LED to see the status. The LED will turn green after the conf is done. Below is the example by using Cyclone 10:
