BQ34Z100 FLASH CORRUPTION

Hi,

I have faced an issue in BQ34Z100 after 7 cycles of complete calibration. At the 8^th cycle the calibration is failed and in the Data flash CODES SECURITY section all the parameters RESET to 000000. Can anyone faced such an issue? Please suggest me what the possibilities are for flash Corruption? Is there any fix for the same?

In Codes Security say Sealed to Unsealed field should be 36720414 but it is 00000000 like that entire section is 00000000. After this event i was trying to import the golden .gg file, i can import but once i pressed write all option other tabs like configuration, gas gauge are changed except codes security section, while importing it is 36720414 upon write all it will become RESET to 00000000

Note:Even if the codes security section all fields are 00000000 gas gauge IC completed 3 more successful calibration.

Regards

Prakash
