    S26KL512S and STM32

    algr_4779301

      Hello,
      Currently I am using an STM32H7B0 with S26KL512S memory. I have read your documents and your LLD drivers correctly. But I am having trouble writing and reading the Status Register Mode from memory
      Memory clock frequency: 60 Mhz
      Can you help me to use this flash?
      Should it be configured at startup?

      Best regard

          Hello,

           

          Thank you for contacting Cypress Semiconductor.

           

          Please ensure no other embedded operation is occurring when attempting to READ or WRITE to the FLASH.  Any commands sent to the FLASH while another embedded operation is executing will be ignored.

           

          Please provide waveform screenshots when READING from the FLASH.  Please include the signal pins as shown

          within the S26KL512S datasheet, page 12, Section 4.2:

              Hello,

               

              thank you for your answers but for the moment the problem comes from the microcontroller.

               

              Best Regards,
