Other Parts Discussed in Thread: BQSTUDIO
Hi,
We have had two occasions in a row where downloading the .srec file into a BQ78350-R1 has failed and subsequent communication with the BQ78350-R1 has not been possible.
The failure occurred on two different PCB assemblies. On the first occasion, replacing the device fixed the problem and downloading the .srec file worked without a hitch.
The second time, we are waiting for replacement chips to arrive.
Is this a known problem, and is it normal for a chip to be put into an unrecoverable state if communication fails during firmware download?
The SMBus data and clock signals look OK and I can see bqstudio trying to communicate if I manually select the BQ78350-R1.
BQstudio version is 1.3.54
and we are using the EV2300 version 3.1m
Thanks in advance for any ideas as to what is going wrong.
Alan Ogburn
