I am unable to program the MCU without using the openSDA usb port. Our target project will not have a USB port. I am using an IAR J-LINK ARM debugger connected to J11. I have removed r76 on the FRDM-KL43Z board and have cut the etch between pins 1 and 2 of J8. Are additional pull up/down resistors needed to use the SWD lines connected to J11?
