Successfully Programmed my device.
Thanks to all.
Will you be so kind to tell us what the final change was that lets you program your device successfully (whatever it was).
Just to have a chance to direct the next one (and there will be one!) into the right direction.
I am curious, you stated you had updated Designer earlier in thread,
so what did "fix" the situation ? Did you have an old Programmer
version installed ?
At last i made new sample of my hardware, with changes in design(small changes) with high precautions, also use proper soldering metod for QFN type of controller.
So at last i conclude at ther is no version issues and no controller type issues it is all about hardware design and soldering issues.
Thanks @Dana & @BOB.
You are always welcome !
