Other Parts Discussed in Thread: BQSTUDIO
Hi,
I'm creating some software running on an embedded Linux system to update the battery chemistry and some other parameters on devices out in the field without hardware access. I have been following SLUA801 and I've gotten to the point where something seems to be happening - but once I run the flash stream file through my programmer the gauge seems to get stuck in ROM-mode and I can't seem to recover it. Also - the program seems to be executing WAY too fast - completely ignoring the sleep timers.
I got the FS file by using BQ-studio and just downloading the DFFS file of the chip that I am testing on. i.e. there are no actual changes to any parameters - I just wanted to see if I can read and write to it.

After this the device becomes unresponsive at address 0xAA and only responds to 0x16 i.e. it seems to be stuck in ROM mode.
According to SLUA541:
However, the device does not seem to exit ROM mode, and trying to do the command steps as shown above manually yields no result - the device is still unresponsive at AA and in fact does not seem to be writing to 0x00 at all:
