My external flash for save image (OAD) is N25Q032A13ESE40F

NVS SPI library support for Micron (N25Qxx) family. is it right? because i see in ExFlash.c - just support Winbond and Macronic not Micron (N25Qxx)

Thanks and Regards

Hi,

ExtFlash.c has nothing to do with the NVS driver. They are two different code bases. Using the NVS driver with Micron is fine.

you mean, i will use NVS driver for communication between cc2640r2f and N25Q032A13ESE40F to save image (OAD)?
Thanks

There is an external NVS example in the SDK called nvsexternal which should be a good starting point.

I'm not sure I understand you. Did the NVS external example work, but you're now having problem with the BLE connection?

Many thank for your support, i have done OAD with my external flash.
about this connection issue, in ccfg.c, uncomment SET_CCFG_MODE_CONF_SCLK_LF_OPTION to use 32.768 Khz external clock
