This message is displayed if there is a problem when programming, if it is just a register setting which is the issue then that register will be marked in red by the GUI. If there are no registers marked in red, and the .INI file has been programmed onto the EVKIT before, then there is likely a hardware issue.
The MAX17201 requires up to 10mA during the programming stage and since the IC is powered by the cell to be measured, the RC filter between the cell and the MAX17201 can be detrimental. If you are facing this issue please reduce the resistance of the RC filter so that there is less impedance, and less voltage drop, between the cell to be measured and the MAX17201.
