Hi,
I'm using an STM32H750XBH6 with an ISSI IS42S32400J-6BL, but the read/write operations keep failing.
I’ve tried setting the CLK to 166 MHz / 120 MHz / 100 MHz / 50 MHz, but it still fails.
When measuring with an oscilloscope, I found that the FMC_Dx pins of the STM32H750XBH6 show an extra waveform in addition to the normal data waveform during output.
I disconnected the 22 Ω series resistors, but the same waveform can still be observed on the MCU’s FMC_Dx pins.
Does anyone know what might be causing this?
