WROVER KIT + OpenOCD + Eclipse Debug Issue

[devil_an]

I use WROVER KIT v3.
When I start OpenOCD bin/openocd -s share/openocd/scripts -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp32-wrover.cfg it print in terminal this:

Then I run Eclipse a "blink" example project with one modification: in blink_task superloop I add printf("TEST\r\n\") that was every 2 second print in UART "TEST" message. When I choose a debug, Eclipse add breakpoint to app_main, show me threads, variables, breakpoint, stop program to app_main and OpenOCD print in terminal this:

Line with "Error: Error reading FreeRTOS thread name" is worries. Than if press Run button in Eclipse, program will run and I can see "TEST" message in terminal /dev/ttyUSB1 every 2 seconds.
BUT... when I try add breakpoint to any line (for example to printf("TEST\r\n\")), Eclipse will stall and OpenOCD print in terminal this:

Info : Target halted. PRO_CPU: PC=0x400D1AB6 (active) APP_CPU: PC=0x400D1AB6
Error: Error reading FreeRTOS thread name

Else one "Error: Error reading FreeRTOS thread name" line. What is this error? After this Eclipse stop debugging... I can`t debug simple program with superloop...
