BQ35100: Fuel gauge stuck in ROM mode

Mridula B

Part Number: BQ35100
Other Parts Discussed in Thread: BQSTUDIO

Tool/software:

Hi,

We are trying to write the golden image file to the BQ35100 by switching to ROM mode. But due to some reasons the device is stuck in ROM mode.

1) Is there any command we can give so that we can exit from ROM mode?

2) Is there any provision to fully unseal the device from ROM mode?

Kindly help us since we are in a critical stage where we are blocked at this step .

Regards,

Mridula

Hi Evan,

Unfortunately we wont be able to follow the steps suggested above since we are not using bq studio to program the file to the device.
Instead we are flashing the image directly from the host mcu .

Is there any commands available which we can use to exit from ROM mode.
