Hi,

I am trying to flash one of my eZDSP Board. But I am getting "flash unlock failed" warning. I have not locked the flash. So i don't know the password also. Does anyone know how to unlock the flash?

 

Thanks,

Vanchana

    What eZdsp kit are you using? Which version of Code Composer Studio? Can you give me some more information about your configuration when you locked the device?

    Hi,

    I had similar problem with tms320F28335,

    one time that the problem was occur, I send data to DSP with serial boot loader (SCI) and after that,DSP worked good.

    one time later I couldn't work with boot loader,and I didn't know why. So I changed my DSP but I kept my first one.

    after a month ,accidentally I used first DSP and it worked.I don't know what happened but now it works.

    So I think if you want at first send your code with serial loader,if it doesn't work change your DSP but keep first one.

    if you find a good solution,please tell me.thanks,

    with best regards,
