Part Number:BQ76930EVM
I have ordered a BQ76930EVM for evaluation. I have went through the user guide ( http://www.ti.com/lit/ug/slvu925b/slvu925b.pdf
- In Battery Management Studio, the IC and battery icon on the left grey out, and come back every couple of seconds (see image below).
- When the icons are not grey, I am only able to click the "Refresh" button once, and some data is obtained.
I followed the cell connection table from another document ( http://www.ti.com/lit/ds/symlink/bq76930.pdf ), section 8.1.1 and connected the cell pack to the EVM as shown in the images below:

EVM connector block and board:
R1 and R50 are installed on the EVM board (0 ohms).
Is the cell pack connected properly?
Are the jumper settings correct?
Am I missing anything else?
Please give me all possibilities so we don't lose valuable time communicating through the forum.
