Having difficulty loading program into evaluation board

Hi,

I am using a Macintosh computer running KDS 3.0.0 and SDK 1.2.0. I have watched the video by Jorge_Gonzalez #3195 about 100 times (if not more) and have completed his example. I am having trouble downloading the code to the FRDM-K64F evaluation board. Using the Debugger, I get the following error alert:

 

J-Link GDB Server failed:

Could not connect to J-Link. Please check if plugged into USB port or Ethernet switch.

 

For more details, see the JLinkGDBServerCL console.

 

When I try to load

JLink_OpenSDA_V2_2015-06-11.bin into the bootloader virtual disk, the desktop computer gives an alert that the disk was not ejected properly, and the green LED to blink fast.  Disconnecting the USB cable from the SDA port, reconnecting the cable and pressing reset causes the green LED to blink slowly.   

 

Is there a tutorial or video I can use to work through this process?

Thanks,

Mark
