Device drawing more current at SWDCLK pin
For devices which doesn't support internal pull down in IO structure, the SWCLK pin remains in a floating state and draw more current.
In initialization SW code, override the SWCLK IOMUX configuration to set the PIPU bit in PINCM register to 1, to enable the pull-up functionality on the SWCLK pin, or switch this pin to GPIO / other function through PF bit in PINCM register.
OR
Add external pull-down resistor near SWCLK pin on the board if customer also wants to fix the floating node current during boot code execution or when the NRST pin is applied.
