Using the DFU loader–OSX
|
||
========================
|
||
|
||
Set up the image loader
|
||
-----------------------
|
||
|
||
#. Open a terminal
|
||
#. Change directory to where the files have been extracted
|
||
#. Source the ``setup.sh`` script
|
||
|
||
Download new firmware
|
||
---------------------
|
||
|
||
To program the new firmware run the command:
|
||
|
||
``./xmosdfu --download new_firmware.bin``
|
||
|
||
Note that once this is done the device restarts. The original factory default
|
||
application is still present but the device is now running the upgraded
|
||
application firmware.
|
||
|
||
Uploading existing firmware from the device
|
||
-------------------------------------------
|
||
|
||
You can retrieve a firmware image from the device, providing an upgrade image is
|
||
present.
|
||
|
||
Run the command:
|
||
|
||
``./xmosdfu --upload currentfirmware.bin``
|
||
|
||
The file ``currentfirmware.bin`` contains the latest upgrade image. This file is
|
||
an exact copy of the data from the flash and can be downloaded to the device
|
||
again to test.
|
||
|
||
Reverting firmware to factory image
|
||
-----------------------------------
|
||
|
||
To revert the device back to its factory (i.e XFLASH) installed state from the
|
||
new firmware, run the command:
|
||
|
||
``./xmosdfu --revertfactory``
|
||
|
||
The device will now only contain the factory firmware and will be running as an
|
||
audio 2 device again.
|
||
|
||
The device will now be running, and only contain the factory firmware.
