bqStudio error code 1470 when programming selected Chemistry

Hi Expert:

I would like to write battery parameter from host MCU but after doing I

get the error code 1470 when programming selected Chemistry.

Please find below test environment & procedure.

1.Test Environment :

HW: 

a.bq34z100-G1 EVM

b.EV2400 with FW v0.28 

SW:

a.bqStudio 1.3.06

b.Chemistry version : 730

Reproduce procedure:

1. Open bqStudio -> click Chemistry to select 0402 -> programming  -> OK

2. Generate Golden Image 

3. Put 0100_0_16-bq34z100G1.df.fs into MCU header file as c-string and use 

gauge_execute_fs function to parse df.fs string to flash data memory of gauge

from HOST MCU. 

4. After procedure 3 the all leds of bq34z100-G1 EVM are turned on .

Any wrong ? And the gauge IC will lose connection on bqStudio

until I click programming button and than click Execute FW button.

5.After all above procedure I open bqStudio and program Chemistry parameter 

again. I get the error code 1470

Could you have any suggestion ?

Best regards,

Wilson
