Other Parts Discussed in Thread: BQ27210
Hello;
Current I build the programmer for bq27220.
Apply 7.2V to connect GPIO pin and got part number/FW version successfully;
But power off/on and met DF is all empty.
I am confusing whehter we need to check programming voltage high time/fall time/voltage timing limit. Like bq27210....
Waiting yr. updating information!
