I have an issue while running the peripheral_spi test example with the
STM32F401 Nucelo board. I have made the hardware connections as per the
peripheral configuration file and tried to run an SPI loopback test.
However, I receive only 0x00 instead of any character that I transmit on
the MOSI pin.

The connections that I have made are:
MOSI pin (Port A_7) connected to the MISO pin (Port A_6)

Can someone help me out with this issue?
