Hi,

I am Farabi who will support your configuration issue.

The nSTATUS goes low during configuration means some setting is not set the correct way.

May I know how you connect the MSEL pins? are they connected to some other controller IOs or are they connected to a fixed connection like pull high/pull low (by switches)?

Farabi

    Hello,

    Do you have any updates? Or you can private email me the schematic of configuration connection page.

    regards,

    The MSEL pins are connected through zero Ohm resistors. We have tried AS Standard (R370 out and R367 in) and AS Fast(R370 in and R367 out) . I have attached a picture.

      Do you need a copy of the .JIC file? We have created one with all combinations of the Advanced options and all behave the same.

      Disable EPCS/EPCQ ID check

      Disable AS mode CONF_DONE error check.
