bq34z100 G1 EVM board: Battery management studio complains "the detected device not compatible with this application"

Other Parts Discussed in Thread: BQSTUDIO, BQ34Z100, BQ34Z100-G1, BQ34Z110

I am currently using the ba34z100 G1 eval board: bq34z1xxEVM.  I have downloaded the firmware but when I load the Battery Management studio,

selected 0100_0_16-bq34z100G1.bqz, but a pop up message says: "The detected device not compatible with this application". 

But looks like I am still able to communicate with the device using the BQ studio. 

I notice that the device version based on what read back from bqstudio is: bq34z100G1 0100_0_06.

So do I have the latest firmware version?  If not, how do I get the latest firmware version?

Is this firmware related issue or some other issues?

(I already downloaded the latest firmware from TI website).

Does anyone know why?

Thanks.

    I've updated the firmware today.

    bq34z100G1 0100_0_06 is the old firmware.

    It seems like the firmware programming didn't work.

    I downloaded and installed this firmware:

    www.ti.com/.../sluc580

    Then in bqStudio go to Programming and select the installed firmware (Default is C:\ProgramData\Texas Instruments\bq34z100G1FirmwareBundle-0.16\bq34z100_G1_v0_16_build_17.srec)

    If programming the firmware was successful restart bqStudio.

    It now should detect the bq34z100G1 0100_0_16 correctly.

    Yes, bqStudio should auto-detect the device after the -G1 firmware has been loaded.

    Thanks for the reply.

    I have a couple of questions regarding the firmware (I am new so it may be obvious).

    Does the firmware gets programmed to the chip or only to the software tool?

    Does this firmware work for the bq34z100 version?  (older non - G1 version)

    What would happen if I program the latest firmware to the non G1 version?

    Does it do any damage to the existing chip?

    Thanks.

    You can program the bq34z100-G1 firmware into the bq34z100 or the bq34z110 device. They should work with bqStudio after the device has been programmed.

    I have a similar problem of device (bq34z100-G1) not getting detected by the bqstudio (ver 1.3.52)
    But in my case, the chip is on our custom board. So we tapped SDA and SCL lines to connect it to the EV2300. uc is not powered ON, during this process. Only the bq34z100-G1 chip is powered ON and also battery is connected.
    Pull ups are 10K on the SDA and SCL lines.

    I also have few questions,
    Is it necessary to power up the chip from Vout?
    Can we still to connect the GND, even when not using the Vout of EV2300?
    and also when I download the firmware from below link,

    www.ti.com/.../sluc580
    it doesn't have any file extension.

    Could you please suggest, where could be the issue?

    Thanks in advance,

    I was able to resolve the detection issue. The problem was in the SDA n SCL lines. They were being somehow pulled by the uC. Isolating them resolved the issue.

    Thanks
