I'm attempting to run through the bqEasy calibration routine for a bq27500 v1.08. I'm using the EVM board and an EV2400 to connect to my computer. Unfortunately, when I get to the 'Calibrate' section I'm unable to run the voltage calibration. The board always reports the measured voltage as 0mV (on the DataRAM panel as well). When I run the calibration, I get the error message 'Calibration Failed! Error code = 5024', which I understand means 'Voltage too large (Overflow) in firmware'.
I have tried this with the board connected to a battery pack through the J8 connector (which I confirmed is charged with a multimeter), both with and without a charger connected to the charger +/- pins.
Does anyone know why the voltage would be reported as 0, and how I can correct this so I can finish the calibration?
Thanks,
Nick
