Hello,

We are using Dart MX8M module with Yocto Sumo and we have added some of our own custom drivers for the some camera sensor modules that we use with it.
Now we followed the procedure mentioned in 
https://variwiki.com/index.php?title=SWUpdate_Guide&release=RELEASE_SUMO_V2.2_DART-MX8M
to update the kernel over Ethernet and at step 2.4 when we upload a new software update image, we have the following error: 

Software Update started !

Can anyone please help? 
Also are there any other methods of updating kernel over ethernet for Yocto? 
Any helpful links or documents are very appreciated!  


Thank you,

Best regards,
