I am using nRF Connect SDK 2.9.0 with Toolchain 2.9.0 and trying to interface Winbond W25Q32 SPI flash memory with nRF21540DK (nRF52840) . I need help with the following: Device Tree Overlay – Proper setup for enabling W25Q32 in Zephyr. Driver Support – Recommended drivers, APIs, or sample projects for working with SPI flash. If anyone has successfully integrated external SPI flash with nRF52840 in nRF Connect SDK 2.9.0 , please share your insights or example configurations. Thanks in advance!

I assume you are connecting some external flash chip to the nrf21540DK since it didn't include a flash chip. The v2.9.0\zephyr\samples\drivers\spi_flash example might be a good starting point. Though it specifically targets the nrf52840DK. The only issue for you would be that the nrf52840 will be using a quad spi part.
