Please see the attached document for a description of the issue being seen.  Here is a summary:

We are interfacing it with STM32L476VGT Cube 4.26.1. Our firmware is running on STM32Cube_FW_L4_V1.12.0 (equivalent to 1.13.0 qspi). We have been able to successfully read the device ID (0x01 0x60 0x19), erase block (cant verify). Below are the routines, and the capture from our Saleae analyzer. I am looking for any guidance to help understand what the cypress part is looking for.

Hi Corey Wilner,

As per my understanding customer is observing issues with erase and read operations. Is customer setting QPI bit in configuration register 2? If yes, they have to use 4 lines for command, address and data.

Thanks and Regards,

Sudheesh
