Build core-image-base fails because of TCF Agent


Target: i.MX6UL Starter Kit
Host OS: Ubuntu-16.04 LTS (x86_64)
Build Environment: Digi Embedded Yocto
Issue: Build images failed due to invalid TCF agent link

I installed the Digi Embedded Yocto following this guide:|System%2520development|_____1

Then I’m trying to build project with core-image-base conf:|System%2520development|_____2

But I’m facing the following issue about TCF agent that can’t be fetched from the following and even on mirrors:

Access to the link: “” on a navigator confirms that (404 file not found).
Here is the right link:

Below is the output of the compilation error:

Checking the tcf-agent.service shows that it isn’t loaded and inactive:

Could you please help me to resolve this issue ?

Thanks in advance.


looks like the location has changed to

note added /c/

you should be able to manually download and place into downloads folder

Thanks Leonid for your answer.

Here how I proceeded to workaround the issue:

I placed the file located in:


And renamed it to: tcf-agent_git.bbappend

Then launched again the following command, and it worked:

bitbake core-image-base

But I had TCF-Agent (1.4 Neon) because in this imported file, it’s configured like this; instead of TCF-Agent (1.5 Oxygen).
