Other Parts Discussed in Thread: BQSTUDIO, BQ27541-G1, BQ27542-G1

Hello, I'm using BQStudio creating some Golden Image Files, namely srec (*.srec) , bgfs (*.fs) and dffs (*.fs)  Files, now, when I need to program other devices with BQStudio what file should I use ? Do I need to program all 3 files ? or probably only one, which file in this case *.srec, or *.fs ?

Thx for any Help ;-), best regards Enrico

    Hi Enrico,

    When you are ready to start programming your files to other devices, you can just use the .srec file.

    Directions to do this in BQ Studio:

    1. Go to the programming tab.

    2. Browse for your .srec file

    3. Press Program, wait until complete,

    4. Press Execute FW twice

    Best,

    Justin

    Hi Justin,


    thx for Your response, I'll do this ;-), btw. I've another question:

    in BQ Studio when selecting the new device bq27452-G1 I did not get the Icon "I2C to HDQ" in the Toolbar, it shows when selecting the NRND- device bq27541-G1 ? Right now I've been using the bq27541-G1 *but* want to replace the bq27541-G1 by the newer one bq27542-G1 in future but I must know how to switch the new device to HDQ- Mode at the end ;-),

    Thx in advance, Enrico

    Hello Enrico,

    I have attached a presentation that goes over how to convert the 542 to HDQ using bqStudio.

    Thank you.

    Hi Fernando,

    thx for the Info, I'm sure it will work ;-), but I cannot realize why the I2C->HDQ Button in Toolbar exist's when selecting bg27541-G1 but not when using the recommend bg27542-G1 ? I think it does the same thing, just imagine You have 100 boards to program, entering the whole command sequence for each will last a whole day :-( ... possibly I'm not the only one using the bq27542-G1 in hdq-mode, so I strongly recommend to talk to the creators of bqstudio to enable this feature- it should be done in one day, I'm sure of it ...

    Just waiting for the next release of bqstudio, best regards, Enrico

    Hello Enrico,

    I fully understand what you are saying.

    The bq27541-G1 and bq27542-G1 although they are similar in functionality, they have different configuration files for bqStudio; this is why the 542 on bqStudio doesn't have the I2C to HDQ plug-in. I have passed along your feedback to the bqStudio team to add the plug-in on the next release.

    Thanks.

    Hi Justin,

    well the srec- files takes really long to program, I think programming the whole firmware is not necessary ( is already done by TI on production ) , so using the *.df.fs - File may be sufficient ? ( probably it contains all the Data from the learning cycle and the cell settings ) I'm I right ?

    Best regards, Enrico

    Hi Enrico,

    You can use the dffs file instead of srec as well, either of these will program the device.

    Best,
