Hello All,
We have an custom board using stm32f446re controller which has 6 PIN SWD JTAG connector.
We are using NUCLEO-F446RE kit as debugger to flash the custom board as explained in "6.2.4 Using ST-LINK/V2-1 to program and debug an external STM32 application" from below link,

Removed CN2 jumpers
Connected CN4 SWD pins of NUCLEO-F446RE to custom SWD connector as appropriate signals.
But we are not flash or debug as we are getting below error in System workbench for STM32 IDE,
