Hi. I'm trying to read data from W25Q64 flash memory.

These are my connections:

And these are my SPI and RCC and GPIO settings:

And these are my functions and main code:

Using W25Q_ReadID function, i could read device ID.

But i can't read data stored on device using W25Q_Read.

these are my result that i think they're wrong:
