Problem Connecting to Internal Arduino on LattePanda Delta

I am trying to connect to the internal Arduino Leonardo on a LattePanda Delta board. The Arduino is on COM4 as shown in Device Manager.

 I can also see the Arduino board info.

In NI MAX the Arduino is showing up on COM 4 (ASRL4)

 When I use the Firmware Wizard I get a message that it is complete, But when I view the Log I see that it could not open device.

 I looked at similar problems and updated the Packet Number.vi but I don't think it is going to work until I get the firmware installed.

Is there any way to confirm that the firmware was installed?

Are there alternatives? Like using VISA communications? 

I only need to toggle four digital outputs lines.

 

Any help would be greatly appreciated.

i never used an onboard arduino with Linx. Are you running windows in the lattepanda? perhaps something in OS might be blocking direct access. you may need to investigate. also i am not sure if LabVIEW 64 bits allow using LINX, but you need to try.

if you need a faster solution, then VISA is your friend. you can read and write data from/to arduino using a conventional sketch (not LINX firmware in exemple)
