Result is approximately 30 seconds @ 200kHz real. I made a snapshot on oscilloscope (I can send it here, too). I see that between JTAG transfers there are delays of around 600us. I then experimentally increased TCK to 1MHz. TCK increased but delay of 600us between transfers was still there. Time of MDW went down to 25 seconds.
For comparison, I connected STM32 with the same setup. Communication with STM32 is incomparably faster. Look below. I see the difference that PIC32 MDW goes to some special function, unlike MDW on STM32. It seems to me, that something inside mips_m4k_read_memory() works bad. Maybe a memory leak? Some systems are not affected with it. But it looks that mine is. One thing confuses me. Why there is so small amount of debug messages for -d3 ?
