Struggling in interfacing MX25R6435F with B-L475E-IOT01A

Hi everyone,

I’m currently working on interfacing the MX25R6435F NOR flash memory with the B-L475E-IOT01A development board using Quad SPI (QSPI), but I’m facing some challenges.

I’ve followed the https://www.st.com/content/st_com/en/support/learning/stm32-education/stm32-moocs/stm32l4-hands-on-workshop.html  but am facing issues with memory detection, QSPI initialization, and write/erase operations.

Hello @Aadi__ 

Did you check the QSPI examples on STM32Cube firmware? 

QSPI flash (N25Q128A13EF840E):  `Projects/32L476GDISCOVERY/Examples/QSPI`?

QSPI flash (MT25TL01GHBA8ESF-0SIT): Projects/STM32H747I-EVAL/Examples/QSPI/QSPI_MemoryMappedDual

You can use it as starting point to implement your application.
