MX7 SABRE schematic: sim card connector J7 and SIM card signals

[demoniacmilk]

hey there!

Id like to place an eSIM on an addon board for the MX7 SABRE.

Connector J7:

When I was looking for possibilities to connect the eSIM to the mx7 through the available connectors I stumbled upon the sim card connector (J7) in the schematic. It seems to be connected to the PCIe connector (J8) only? I cannot find the net respective labels anywhere else.

SIM card Signals:

SIM1P1 is part of the EPDC connector (EPDC_SD08..12). Simply connecting an eSIM to these pins (and adjusting the pin mux) should do the trick? Are there any drivers ready for (e)SIM cards under Linux?

Thanks,
Regards,
Lars
