BQ27510-G3: BQ27510-G3 - restore to factory default

Part Number: BQ27510-G3
Other Parts Discussed in Thread: BQSTUDIO

Dear Support,

I have a BQ27510-G3 in an epoxy potted device.  I believe that a the BQ27510-G3 is stuck in ROM mode. It will not acknowledge commands on address 0x55, but does seem to still communicate over address 0x0b.  Is there a way I can reprogram the chip back to factory status?  At the moment, BQ studio does not communicate with the BQ27510-G3, but I believe that is because it is stuck in ROM mode.  Thank you in advance for your help and assistance.

    Hi Jam
    How did the gauge go into ROM mode in the first place. The gauge doesn't just do that randomly

    If it is stuck in room mode, then you should be able reprogram the device using the firmware found here.

    Once you are connected to the device, and have bqstudio started, select the gauge from the pop up menu and then go to programming. Select the firmware file you downloaded by browsing to it location and then click the program button. After that you hit the execute FW button.

    thanks

    Hi Onyx,

    Thank you for your reply.  The gauge was intentionally put in ROM mode as part of a first time boot-up program.  The program configures this particular chip and other devices with an initial configuration.  Unfortunately, the code was not written very robustly and does not handle errors gracefully.  I believe it failed partly through the procedure and exited.

    I'll try the above process and see if I can get it back to original status.

    Thank you for your help.
