Hello,
I would like to use fstorage function, but when using the example of sdk 14.1.0, I had some errors, please help to let me know what problem is and how to define the start address, end_addr address....
* last page of flash available to write data. */
.start_addr = 0x0007F000, // by 0x800000
.end_addr = 0x000FF000,
I don't know which address I can use in the memory map(512 kb), I refer the following memory map, and I use the command to check memory (data) : nrfjprog --memrd 0x0007f000 --n 0x100

thankful for your support in advance, thanks.
