I have a board that I can't connect using Fusion Digital Power Designer. I am getting the following error. This board has "4" TPS544B20 devices. The tool is able to scan all 4 devices but then halts with the error shown below.
There appears to be PMBUS activity (SCL and SDA are toggling) but then at some point both lines are driven low and stay low.
Any thoughts on what is going on here? This board was working fine last night.
There are 2 other devices on the PMBUS. I am trying to see if I can disable these devices to see if I can connect.
