I am working with MagniV MTRCKTSBNZVM128 BLDC sensorless kit, (MCU part no S912ZVML12 MKH). My requirement is to program EEPROM memory. I am able to program the EEPROM sector but after Power reset or when code is flashed again, EEPROM is set to default data i.e. FF.


From Pic 1 you can see that 06, 07, 08 and 09 is written but when I downloaded the code next time EEPROM get sets to FF (see Pic 2).


I want to see the updated data on EEPROM even after re-downloading or power reset. 


Please let me know possible reasons and solution for this.
