Hi,

Apparently something is wrong with AS configuration pins on your board. Are you having the same results on other boards as well? If yes, then try taking look at the AS Mode configuration pins status when you initiate the configuration and when the configuration completes. Are all the signals showing correct state or one/few pins are showing weird state? Try to monitor the status of nCONFIG, nSTATUS, nCE, nCEO and CONF_DONE pins during and after configuration in AS Mode.

I don't know how much it will help, but you could also try followings:

Hope this helps.
