Salvador, thank you, I forgot "reset init". Anyway, programming and debugging is terribly slow. I use Segger JLink with TCK set to 200 kHz. Programming of the chip is even incorrect. So I tried to burn the code with Pickit3 and then connect with OpenOCD. single step takes about 20 seconds - excerpt of the Openocd log is below. I don't know if it is a problem of PIC32 target or JLink interface. I tried different TCK settings but still the same. Can somebody else check where is the problem ?
