Hello @AAree.1​,

The S26KL512S is HyperFlash memory, Please make sure you are using the HyperBus protocol.

Can you please specify the mode you are using it with?

Thank you.

Hi @AAree.1​,

When using the STM32U575, unfortunately, the automatic status-polling mode cannot be used with HyperFlash™ memories. It is a known errata, please refer to the "STM32U575xx and STM32U585xx device errata" for more details.
