BQ35100: Factory Reset?

Part Number: BQ35100
Other Parts Discussed in Thread: BQSTUDIO,


Is there a Factory Reset command? This would return the device to the state when it has just left the factory.

I've already found a problem with the firmware I'm developing in that I'd changed a setting during early experimentation, which my firmware then came to rely on, so on programming a new part, this didn't work.

Of course I can try a new part but we only have a few devt. boards!

I know that there is the RESET: 0x0041 command but I think this just does the same as power-on reset (i.e. taking GE low and high again).

I've had a look at the technical reference manual but I can't see how to do it.

  • Hello Simon,

    If you need to reset the values, you can use the import defaults in bqStudio. It is in the top right of the bqStudio Data Memory tab.

    There's no command that will reset the flash memory to defaults.

  • Hi Wyatt.

    Thanks a lot for confirming - that saves me hunting through the documentation!

    One thing I noticed is that when the BQ35100 is first used it is in a special Fully Unsealed mode. It is special because it will not normally power up in this mode, even if you set it and then power it down straightaway and then power it up again. As soon as you Seal it, it leaves this special mode.

    I think it is in this mode to make initial configuration easier to do. I would guess that it is not possible to put it back into this special mode again.
