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:

Please provide waveform screenshots at your earliest convenience.
