Hello,
Is there any requirement for the SS multiplexer control signal on the FX3S. I am going to use the GPIO_38(J1).
I have two uSDcards on VIO2 and 3 respectively, they need 3.3V, so GPIO is in VIO2, that would be ok, also in my routing.
Thanks in advance...

Hello,
Since you have mentioned that you are using two uSD cards, I understand that you are using 4-bit storage interface on the S0 port. In that case, the GPIO_38 pin acts as a normal GPIO pin. This pin comes under the VIO2 power domain as you had mentioned. This can be used as a normal GPIO pin with no further requirement.
Best regards,
