Hi, i try to using QSPI in STM32H743( the STM32H743_Nucleo ) to received data, the programming IDE is STM32CubeIDE, and i used it to generated and assign pin and parameter. The clock and NCS pin is probed to oscilloscope, the code is as followed, when the program started, i can not see the clock and NCS shown in the oscilloscope, the NCS is always high and no clock signal, do i miss something to setup or coding ?
Best Regards
thank you
