BQ34Z100-G1: BQ studio - Chemistry update fail

Kevin Picot

Part Number: BQ34Z100-G1
Other Parts Discussed in Thread: BQ34Z100EVM, BQSTUDIO,

Good evening,

I'am facing a problem with BQStudio and BQ34Z100EVM.

Updating Chemistry lead to error code : 1721 

Red message : "Chemistry programming error : Chemistry Checksum did not verify

Other calibration data, and registers access are ok

Tried with BQ Studio 1.3.52 (Latest) and 1.3.59 (For testing purpose only)

EVM réf : BQ34ZxxEVM / PWR111 rev B 

Part number : BQ34Z100-G1

Connected over I2C using EV2300 HPA002 module

Connection ok

The only clue I get is a device discrepancy at BQStudio start :

Auto detected device 0100_0_06

While available versions on the list are 

0100_0_15-bq34z100G1.bqz

and 

0100_0_16-bq34z100G1.bqz

Tried both, showing warning "Proceed at your own risk"

General behaviour seems ok - Excepts chemistry update.

Any idea welcome, thanks for your help.

Regards

Benoît
