I checked the reset pin and measured 1.250V. Is it correct?

If I try to use OpenSDA instead of Jlink, the following error occurs:

This is strange because when I use the 0N77P version, everything works, but with 0N47, I cant.  

I would very much like an answer as I have customers requesting my product. I have already sent prototypes to 0N77P version, which I have no more.

I put the PS32K144UFVLL0N47 on the EVB FRDMPK144-Q100, but even so I was not able to write / debug. Is 0N47 hardware different from 0N77?
