CC-MX-JN58-Z1: How to enable usdhc1 interface

Hi all,
I was wondering if there’s a tip to enable the USDHC1 interface on the non-wireless connectcore 6UL module.
I use in my custom design a non-wireless module. I wired the USDHC1 interface to a microSD socket (ball K19, L19, W19, L20, K20, M20).
On the evaluation board, the USDHC2 is wired to the microsd socket (as the wireless variant uses USDHC1 for WLAN).
Any ideas will be very appreciated.

Probably a problem with assembly process.
Indeed by testing another prototype it works.
