Serial Memory Library Release Notes

Provides functions for interacting with an external memory connected through its Single/Dual/Quad/Octal SPI interface.

What's Included?

  • APIs for Read/Write/Erase operations
  • Supports Execute-in-Place (XIP) mode of operation
  • Accepts the configuration generated by the QSPI Configurator tool
  • Allows for providing information to the programming tool to program the external memory.

What Changed?

v3.2.0

  • Fixed an issue with enabling octal mode for SMIF

v3.1.0

  • Documentation update

v3.0.0

  • Support SMIF MemNum interface instead of MemSlot interface

v2.0.0

  • Renamed library from serial-flash to serial-memory. All APIs were renamed from cy_serial_flash_* to mtb_serial_memory_* and all macros were prefaced with MTB_SERIAL_MEMORY_* .

v1.4.3

  • Added functions for attach/detach to pre-existing peripheral configurations

v1.4.2

  • Added support for CAT1C devices.
  • Switched driver from PDL functions call to corresponding HAL calls, where it is possible.

v1.3.0

  • Added support for CAT1B device - CYW20829.

v1.2.0

  • Added support for HAL API v1 or v2

v1.1.0

  • Added the following functions:
    • cy_serial_flash_qspi_read_async() - Supports asynchronous (non-blocking) read using fixed DMA resources. Refer to the API reference manual for details on the list of devices supported for DMA operation and the exact DMA resources used.
    • cy_serial_flash_qspi_abort_read() - Aborts an ongoing asynchronous read operation
    • cy_serial_flash_qspi_set_dma_interrupt_priority() - Changes the DMA interrupt priority
  • Implemented thread-safety for use with multi-threaded RTOS environment using the abstraction-rtos library
    • Add DEFINES=CY_SERIAL_FLASH_QSPI_THREAD_SAFE in the Makefile to enable thread-safety
  • Updated cy_serial_flash_qspi_get_erase_size() to support memories with hybrid sectors

v1.0.2

  • Added new function cy_serial_flash_qspi_get_prog_size() to get the programming size
  • Minor documentation updates

v1.0.1

  • Minor update for documentation & branding

v1.0.0

  • Initial release
