ISE 14.7 + Mojo V3

I wanted to play with FPGAs so I bought a Mojo V3 board ( (FYI I got cheaper from another site). To use this board you need the Xilinx ISE software which is available for free. Xilinx provides two methods:
1) Download a pre built VM with the ISE software already installed
2) Download the install files and do it your self.

The obvious choice I thought would be option 1. I download the VM from here (

Here’s my quick review of the VM:

  • It uses Oracle Linux 6.4 running Kernel 2.6-32.358 which can’t interface with the Mojo
  • Despite my best efforts I couldn’t change enough settings to make it interface with the Mojo V3. Oracle Linux kept loading the Mojo as ttyUSB0 instead of ttyACM0, and I couldn’t change that.

After that experience I decided to build my own VM but this time use Ubuntu as the base system. I used Ubuntu 16.04 and everything worked beautifully!

Bluetooth Headphones with Dell XPS 9550 & Dell Wireless 1830 Card

I have a Dell XPS 9550 laptop with Windows 10, which uses the Dell Wireless 1830 Wifi + Bluetooth card. My bluetooth mouse connected and worked fine. I tried to connect a Plantronics Backbeat 505 bluetooth headphones to the laptop, it would pair but not connect. After much trial & error the solution is this:

  1. Download and install Dell Wireless 1830 Bluetooth Application (Communications_Application_8R3ND_WN32_12.0.1.720_A00.EXE) 
  2. Update the drivers for Dell Wireless 1830 Bluetooth via Windows Update

And this worked! Hurray!

Update 1: The bluetooth headphones are still working but the audio is a bit choppy. I don’t have a solution for that yet.
