Hello

 

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.

 

Regards,

Rajneesh
