When MCU（stm32f105） communicates with flash（W25Q64JVSSIQ）, it is found that the waveform of MISO pin is incorrect. Please tell me why this problem occurs。
We found the reason. The wrong waveform was generated in the process of erasing FLASH. And the SPI frequency needs to be lowered. If the frequency is increased, the waveform will be normal. If I use the following settings, the erased waveform will...
