To test usage of the bq27621, we bought the BQ27621EVM-G1 board and the BQ27GDK000EVM eval kit. I can open bqStudio and read the registers from the bq27621, but I am unable to discharge using the GDK software.
During discharge, (constant current, constant power, or pulsed load) I will get:
Tue Nov 24 16:43:20 PST 2015: Start Task: Discharge ( Terminate when Seconds = 60 )
Tue Nov 24 16:43:26 PST 2015: End Task (Unexpected): Discharge - false
Tue Nov 24 16:43:26 PST 2015: Complete!
As far as I can tell in the quickstart guide, all I need to do is run the GDK to use the programmable load. I have put a 330ohm resistor across the external load ports, in case it is expecting an external load, but that didn't seem to help.
Is there another setting/jumper/switch/resistor that I have overlooked?
thank you very much.
