I am thinking about upgrading to a ULink PRO. Is it faster downloading to Flash than the regular ULink2?
My main concern is: How long does the battery last on the ULINK PRO? In other words, what is the life expectancy of the ULINK PRO?
This is since the battery can not be replaced, and it seems the Ulink PRO dies when the battery is empty.
>>please inform me how to solve the problem
It suggests the part is not powered or connected correctly.
The connectivity you have described doesn't really help diagnose the problem. Quite a significant number of pins need to be connected on the part, along with several capacitors on the internal regulator. Provide a schematic. Review the voltages on the VCAP1 and VCAP2 pins, and the state of the NRST pin.
