Hi, when I went from a two-board msp432 launchpad and SENSHUB stack to a four board stack, I started getting firmware I2C errors accessing the SENSHUB MPU-9150 IMU (on UCB0), but not the other sensors on the SENSHUB (also on UCB0). The errors go away if I connect a protocol analyzer or scope probes to UCB0 I2C (via J2 pins on the SDCardReader). I have attached a scope screenshot of MPU-9150 initialization (which is working with the scope probe attached). Any suggestions for what to look for and/or solutions would be sincerely appreciated. The scope probe is a 10:1, with 10 MOhm &
