LAN9253 QSPI Communication: Request for Existing Libraries or Examples

DDS · ‎2025-12-01

Hi,

I’m working with the LAN9253 and an STM32F446ZCH6, using Quad-SPI for Ether CAT communication. I attempted to interface with the LAN9253 over QSPI using the STM32 HAL libraries, but I haven’t been able to get it working.
Are there any existing libraries or reference implementations available for using QSPI with the LAN9253?

Thank you,

Deekshitha.

Hello @DDS;

First of all, I recommend you to check whether the QUADSPI interface supports LAN9253 device. For that, please refer to Overall FAQs for QUADSPI/OCTOSPI/HSPI/XSPI - STMicroelectronics Community.

I couldn't find any examples for connecting LAN9253 to QUADSPI interface. But, I advise you to look at AN4760 and QSPI examples may help you.

Thank you.
