Power management forum – Recent Threads http: We thought we might be able to read a device ID – or some other factory-loaded register – to simply verify that the HDQ interface is working on a unit under test, using the BQA with minimal connections to the IC 3. Are you a developer? I want to write a golden image file to the bq I hope you can help me find out why the calibration cycle is not working properly.

Hello, I want to write a golden image file to the bq What tools are required?

I am looking for system side fuel gauge IC for Li-ply battery. How do I decipher a “learned” part’s data file from the EVM to obtain parameters to embed in our micro’s initialization code to the upon recovery from a reset? Thanks in advance Joseph. Collaborans were once again very active, so here’s a look at their contributions. How to initialize bq?

XDA Developers was founded by linuux, for developers. Please share your comment to me. And Linux battery driver gets its information from battery’s fuel gauge chip. I have some oceanfront property in Colorado that you might be interested in if you seriously think this app does anything at all that pertains to battery life or indication. Best regards Kjell Ramberg. Hi I want to use an eq34zevm with an 6-cell li-po battery.


[PATCH 2/5] power: sbs-battery: rename internals to new name

Default Linux driver updates Design Capacity register offset 10 and Default Design Capacity offset 14 remains unchanged. Are you the publisher? Subscribe to Thread Page 68 of 75 First 18 58 66 67 68 69 70 Last. Sent from my MB using xda premium.

Linux-Kernel Archive: [PATCH v5] power: bq20z devicetree init support

After a great time in Vancouver, Collaborans are headed this weekend to southern France to attend and speak at the edition of Capitole…. Any ideas as to why the SOC is so far off even after performing the learning cycles. Claim or contact us about this channel. Battery Charger and Fuel Gauge. Let the battery relax for 18 hours 3. Dear all, We are still using the bq20z75 V. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality.

Update Status doesn’t go to 1 and Qmax doens’t updated. I know that the optimal thing would be to increase the value of the sense resistor to use the full range of the ADC but that part of the system is fixed because it is part of the enclosure itself.


I have seen some cases where some of the cells are more or less complete exhausted, voltage down to 0,V but still the bq is not entering sleep mode consuming power from an already exhausted battery pack. Write calibration results to data flash.

What is the difference between them? I hope you can help me find out why the calibration cycle is not working properly.

The debunked myth that it does anything of the sort is rooted no pun intended in gross ignorance of how Android works and how lithium ion polymer batteries report their charge level.

Hope anybody might have an opinion if there is any parameter that could prevent the shutdown llnux to work OK.
