Shirish,
Thanks a lot for your assistance.
That is what I did in the first place, - downloaded the EV2400 Support Components_ 20110524.exe but when I should run the EVSW (09.99) after running this sw i got an error message (399?) and nothing worked.
I re-installed both the drivers and the TI EVSW (09.79) and suddenly everything is working fine. I am using Windows 7 - 64 bit.
I am totally dependent on a working bq Evaluation Software for my R&D work so in fact I am glad everything works fin now,
Best regards
Kjell
