I am working on FRDM-KW40Z development board. When I was plug the USB cable it was ask me to download bootloader. When I download OpenSDAv-2.1.bin by copy and paste. Then after I was just unplug and then plug the usb cable. None of the LEDs are glow.
And when I am inserting battery into device it is working (flashing all red leds). Can anyone help me what happens with development board?
Do I need any jumper setting to gives USB power?
Any help will be appreciated.
