Trouble Connecting to the MPU6050 EV board

By christoph_mammitzsch , 8 November 2011

Hello, we are having trouble connecting to the MPU6050 EV board.
Please see narrative of problems below. We appreciate any recommendations and would be happy to answer any questions from you.
Thank you.


Using MPU6050+3 axis magnetometer EVB connected to EVB_INVARM_A Win XP 32-bit OS

On MPU6050EVB:
Jumper Vdd SEL : set to Vcc
Jumper V_logic SEL: set to Vcc

On ARM EVB Jumper set to 3V

Communicating to PC via USB

On powerup: red LED solid
Green LED near ARM processor is flashing at ~ 2 Hz

Upon opening MPU6050 demo V2.11 software:
“Cannot retrieve the ARM firmware version. Did you connect the device to the PC USB port or through an USB patch cable? This program will now exit.”

Then
“ARM firmware version type UNKNOWN for UNKNOWN is incompatible with this application. Upgrade ARM firware to “MPU6050 V1.3.1” or higher.
This program will now exit.”

Program then loads but is not functional. Bottom left shows “ERROR:
No sensor board detected”. Two error messages above then repeatedly appear.
