BQ78350: Battery Management Studio Communicating Failure

Yusuf KAYA

Part Number: BQ78350
Other Parts Discussed in Thread: EV2400,

Hi,

When I connected the my board to Computer through EV2400 Interface, I could enter some parameters at the beginning. After a few connecting and removing, the battery management studio doesn' t work and communicate my board. Sometimes the program receives the address of my board then the connection is interrupted again.

I am using the 36-48V reference board of the Texas Inst.

Do you have any suggestion to solve problem? Thanks in advance.

Since you are using the EV2400, have you removed the shunts and pull-up resistors on the BQ769x0EVM board?
This is required for the EV2400, but they should be left in place if your using the EV2300.
FYI, if flashing a firmware SREC file, you need the EV2300 for the BQ78350 due to a driver incompatibility with the EV2400.
