Hi Niharika,
do you have an other stm32f4 board at hand (e.g. stm32f4discovery) to
confirm it's the same issue there? A scope or logic analyzer would be
useful to check if CLK and MOSI are running.
The general setups seems reasonable in general. In case the issue
persists please add a note to this issue where we collect leftovers from
recent SPI reworks in RIOT.

Hi,
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?
Thanks,
Niharika.
