Other Parts Discussed in Thread: BQ25798, BQSTUDIO
Hi,
I am currently testing a Powerbank USB-PD solution and I use the USB-PD-CHG-EVM-01 demo board seems to match my need. I would like to program the BQ25798 registers myself in order to select the battery protection values. However, it is not possible to write to registers, once the board is powered on, defaults are written and the write data is overwritten.
While browsing the other forums, it seems that this problem is related to the WD timer but it is impossible for me to enter the host mode despite following the instructions in the datasheet of BQ25798.
below the configuration of the map and the tools used:
Setup-up: with active JP2 jumper
config TPS25750D:
{"questionnaire":{"version":"7.0.3.13","answers":[0,2,3,0,0,null,1,null,1,null,0,12.6,2,0.4,0.76],"options":{},"configID":"0000","vendorID":"0000"}}
Capture BQstudio:
1. My problem really comes from the WD Timer?
2. Is it possible to provide me with the procedure for entering in host mode?
Thank you!
