How to prepare Delta firmware package for EC20?

Hi all,

How to create a DFOTA package to be hosted on our FTP server? We want to push updates to the application code OTA. Is that possible?

Any help is appreciated.

Thanks for the Update. However EC20-delta-gentools.tar.gz is not provided with the SDK. Can you provide me with the same?. I am using EC20-CE-FILG and

Rev. EC20-CE-FILG_QuecOpen Firmware_Release_Notes_V0604
Date: 2019-08-22

Specifically states that they have deleted Deleted DFOTA tools from SDK. Why is that?
If there is an updated release of the SDK, please share it with me.
