BQ34Z100EVM: NOT ABLE TO ACCESS/CHANGE REGISTERS IN BQSTUDIO-(VOLSEL)

Part Number: BQ34Z100EVM
Other Parts Discussed in Thread: EV2400, BQSTUDIO

Hello Team,

I had connected the BQ34Z100EVM as per the guidelines shared in User Guide with all latest firmware versions. I am using a 12.6V battery (2600mAh) battery pack-3s mode.

After Connecting the EV2400 and BQ34z100EVM using i2c cable, I clicked on UNSEAL mode to make the device in UNSEAL mode in command window on right side.But I am not able to verify if the same has been implemented as I am not able to change the registers. I am always getting error saying " READ OF DATA WRITTEN FAILED COMPARISON". I am not able to make VOLSEL as 1 to configure it for external battery mode. Can someone please help me with this on how to configure these things and fix asap

Also the registers are showing in LOCK condition .
