Hello DevZone,
I am trying to integrate an external flash memory device W25M02GWZEIG chip with nRF52840 over QSPI. I had followed the sample code - SPI- Flash in the Zephyr- RTOS codebase for nrfConnect as follows,
https://github.com/zephyrproject-rtos/zephyr/blob/main/samples/drivers/spi_flash/src/main.c . Attempted setting the overlay config with different pins owing to my system pin-mapping.
Therefore, I would like to obtain insight for setting the overlay for this particular chip(W25M02GWZEIG) using QSPI.
Having looked into the code for erasing, reading and writing multi-sector data into the flash, I would like to retrieve and send data over BLE to an app(custom) for my application. I am trying to store data from an IMU onto the chip and send it later to an app when needed.
Kindly help provide guidance in how I can use the QSPI setup for flash to store, retrieve and send packaged data over BLE to my application. Provide any suitable resources to help with this regard.
Thank You.
