We have found that the NRST pin is in Low state after start. This is problem for us because we'd like to use OpenOCD in JTAG mode and OpenOCD will send an active low pulse to NRST pin. Is there any solution for this? Or any other stm32 eval board...

You need to open SB11 to disconnect the on-board STLink's T_NRST to the target NRST (see Fig.10 in UM1472).

Update the ST-LINK firmware, I think around v25 or v26 they held the device in reset
Check what you have and report back. Update with ST-LINK Utilities, STM32 Cube Programmer, or the stand-alone tool.
