All Shipping is complete! And, new Firmware image is available

I think by now all of you have your Acusis units. If you haven’t, please let us know, we’ll figure out what’s wrong.

Also, if you have an XTAG programmer, we have some good news as we tuned up a new version of the firmware. Please give it a try with the steps below. The same instructions were posted on XCore.



Just unzip the file below to get the files needed for the installation instructions below:

Acusis software package v1.1.2.0

Firmware Installation


There are 2 ways to install Acusis firmware updates, either via USB or the XTAG programmer

Updating via USB

Use the included ‘xmosdfu’ upgrade tool to load a new Acusis firmware image (e.g. Acusis_v1.1.2.0.bin). The upgrade tool is included for OSX and Linux (x86_64). A Windows version of the tool is in the works.

To use on Linux:
  1. Open a terminal window and cd to this release directory.
  2. cd host/Linux
  3. sudo ./xmosdfu 0x11 --download ../../firmware/Acusis_v1.1.2.0.bin
To use on Mac:
  1. Open a terminal window and cd to this release directory.
  2. cd host/OSX
  3. ./xmosdfu 0x11 --download ../../firmware/Acusis_v1.1.2.0.bin

On both platforms, you should see output similar to the following:

VID = 0x20b1, PID = 0x11, BCDDevice: 0x100 XMOS DFU application started - Interface 3 claimed Detaching device from application mode. Waiting for device to restart and enter DFU mode... VID = 0x20b1, PID = 0x11, BCDDevice: 0x100 ... DFU firmware upgrade device opened ... Downloading image (../../firmware/Acusis_v1.1.2.0.bin) to device ... Download complete ... Returning device to application mode

Afterward, you can verify that the upgrade was installed by running:

./xmosdfu --listdevices

Within the output, you should see the line:

VID = 0x20b1, PID = 0x11, BCDDevice: 0x1120

Where BCDDevice of 0x1120 indicates that v1.1.2.0 firmware is running.

Updating via XTAG

It’s assumed that XTAG users have already installed the XMOS SDK and have the xflash tool available. To install, open a terminal window and locate the .xe image to install (e.g. Acusis_v1.1.2.0.xe). To install, run xflash:

xflash --no-compression Acusis_v1.1.2.0.xe

You may see a couple warnings with the following output at the end:
