Problem in BLE NrG2 internal Flash using for variable saving

Pshar.1 · ‎2020-05-31

Our test eeprom code taken from samples codes with address

Flash begin address 10040000 worked but not getting reprogram until boot pin gnd to 3.3v then gnd.

Flash address 10042850 is working but creating problem to reprogram

Then we tried 1007000,10060000, 1005000 not worked.

To program we hav to grd boot pin then high sort of reset then only we are able to program..n by doing this we r able to make our code work once for that 10042850 flash address n not for other values..either boot pin reset is not taking place or v r doing smething wrong while choosing flash addressess.

can any please help i want to save 6 uint32_t data type variable in internal flash of bluenrg 232 SOC. How can i do that i am taking the above code as sample code for saving .
