We are aware of an issue with some vehicle unit downloads using the digivu and have released several software and firmware updates to resolve this.

There is a power related issue with certain Stoneridge Smart2 tachographs that is affecting vehicle unit downloads made using the digivu. This issue is isolated to download devices that are powered solely by the tachograph’s download interface as is the case with the digivu. It results in corruption to the device’s storage that can affect subsequent download attempts. If you have encountered the problem (FF 01 04 log entries, downloads failing in Stoneridge Smart2 tachographs etc), you will need to follow the process outlined below.

We have implemented a workaround in digivu firmware version 2.16, which can be enabled with a setting. To be able to interact with the setting, we have also released updates for digiconnect (version 5.51) and current digipostpro (version 1.16).

If a digivu has already encountered the issue, it is important to follow the specific order of operations (below) to update the device and enable the workaround. If these steps are not followed, the firmware update may fail due to storage corruption and the customer would need to use the ‘emergency firmware rollback procedure’ to restore the device to a functioning state.

This workaround is not being enabled by default as it causes some delay when the digivu is connected to a PC or digipostpro and its behaviour may cause some customer confusion.

Please follow the instructions below or watch the video which will walk you through the process.

1. First, close any other program that interacts with the digivu.
2. Update digiconnect to 5.51 (or later).
3. Connect the digivu, refuse the prompt to update to version 2.16. Ensure all files have been archived, then go to ‘View file on device’ and use ‘Delete All’.
4. It is now ‘safe’ to update the digivu firmware. Click ‘install’.
5. Once the update is complete, go to ‘Configure Device’, select ‘File Storage’ and tick the checkbox for ‘Prepare file system for tachograph download.
6. Click ‘apply’, then ‘OK’ to apply the configuration change and trigger a reboot. The device will perform an initial file maintenance process that could take as much as two minutes to complete. While this is happening, the device will not communicate with digiconnect and the status LEDs will not show their normal behaviour. Instead, both LEDs will blink amber and may appear quite dim until the operation completes.
7. Once the digivu lights have gone green and has reappeared in digiconnect, click ‘View Download Log’ then ‘Clear Log’. Starting with an empty log makes it much faster and easier to investigate if any further issues are encountered.

With this new setting enabled, the device will initially spend some time performing file maintenance tasks when it is connected to a PC or digipostpro. While it does so, it will not communicate with digiconnect or the digipostpro and the status LEDs will blink amber.

After the initial operation, it will normally take much less time to complete, generally less than 10 seconds.

If you need to perform an emergency firmware rollback, please follow the steps in the video below.
