BQ27421 Issues connecting to bqEVSW

Other Parts Discussed in Thread: BQEVSW, EV2400

Hi Team,

SLUA595 says to use EVSW in Figure 1. When I run bqEVSW it hangs my product’s I2C bus and says it is connected to an incompatible device.  I think I remember seeing somewhere mention of SMBus with this software so I tried that port but it also doesn’t work.

Can you please provide some guidance as to why my I2C bus is hanging like this?

Thank you,

Jared
