MMC is unable to detect RTM Presence signal
Created by Henrique Silva
The RTM_PS# signal is connected on P0[29], which doesn't have an internal pullup resistor like the others GPIOs. Since this pin remains floating when configured as input, we can't detect wheter the RTM board was inserted or not, since the insertion process involves grounding the RTM_PS# signal.
Solution: Insert external pullup resistor on the RTM_PS# signal or route it to another pin

I'd rather put an external pullup, if this pin has no other particular use.
