I have a BMS setup using BQ76940 and BQ78350. When I star the system and programmed the default firmware it starts fine and shows voltage of 3 cell which is default setup. Once I set the AFE cell map register to use cell numbers 1,2,3,4,5,6,7,8,9,10,11,12,13,15 (I have sorted pins VC13 and VC14), the BMS shuts down within 2-3 seconds. My Computer no longer detects the BMS while EV2300 is still showing connected. Below is the screenshot of the software.
Can someone through some light on possible reasons?
