    Hello,
    First of all i want to say thank you for trying to assist me, but i'm still stuck with my keil MCB251 evaluation board without knowing how to download program to it or debugging it through keil uVision3 or through any other 3rd party software.
    Therefore i'm asking if u can redirect me to any other technical support that familiar with this product and probably know how to deal with this problem.

    thanks

    when asking micro, e-mail him

    if you had asked me I would have recommended contacting Keil technical support.
