Other Parts Discussed in Thread: BQSTUDIO
After succeeded to generate gm.fs file for bq27421, so we want to program this gm.fs file to the device, I've read each commands in gm.fs file.
Now I have a question,
There's explained in TRM, some commands such like "SET_CFGUPDATE" requires to be in unsealed state.
But there's no unseal command described in gm.fs file, so do I have to send two words of "Sealed to Unsealed" key (i.e. process "W: AA 00 00 80" command twice) before processing the gm.fs data ?
