hence it is set to 1.8 V.
Warning
In case you have set V
SDIO Reference Voltage
configured to be 3.3 V.
Please note, if V
reference voltage to 1.8 V since this would create a short between
3.3 V and 1.8 V.
To set V
to 3.3 V execute the following instructions.

1. Unsolder R8.
2. Place a 0 Ohm resistor (0402) for R13 or bridge it with a solder blob.
