Dale reacted to USWaterRockets in I2C errors with four-board MSP432 launchpad stack
Are there multiple boards with the I2C pull-ups installed? Too many pull-ups in parallel could lead to errors.
Alternatively, Having no boards with Pull-ups installed on the I2C lines means it should probably never work.
Also, If this is a signal integrity issue, you could try slowing the I2C clock rate down and see if the problem goes away.
