Writing to internal FLASH

Products & Technology XIAO
#1

Thanks to the amazing support of this community I have a system writing to external FLASH and communicating via BLE.

I was looking to understand the memory map of the NRF52840 (non mBed) and how I might write a few bytes to the internal 1Mb FLASH. This way I can be assured that when I format my external 2MB Flash, I can maintain some persistent preferences.
I understand the internal is used for program memory but some should be available for the user.

Hi there

Hi and thanks for the response.

This demo appears to be for the external 2MB QSPI Flash that I have working well. I’m looking to add data to the internal 1MB Flash.
Warm regards,
