bq30z55-R3 Checksum

alec

Hi sir,

I am using bq30z55-R3

Customer found same dataflash setting but different checksum

Is there any hidden dataflash setting will cause checksum different ?

How to check if hidden item are different?

Thanks

Hello Alec,

Could you provide the procedure they followed to generate the checksum and what they were modifying in dataflash?

Sincerely,

Wyatt Keller

Hello Wyatt,

They will not modify, just used to check whether the settings have been modified

SMB Command 00 Word(HEX) 05 Write

SMB Command 23 Read

from Pro page of bq evsw

2 batteries with different checksum but the same dataflash

Chemistry ID are the same.

Are there any hidden items that will affect checksum?

Thanks

Can you dump gg files of these two batteries and share them with us?
