Hi David,

I'm afraid that you must now replace the IC. If your DFI and IC firmware are different versions (v1.11 vs. v1.12, for example) then the IC will be locked up when you program that DFI to it.

If you want to update to a new F/W version, you must also update your DFI or create a new DFI. Please follow the instructions in this app note very carefully if you need to update an old DFI for a new firmware version:

Updating Firmware WIth the bq2750x and EVM

If you don't do it properly, the checksums will be different and your IC will be unusable.

Regards,

David
