Hi
When I try to build NCS sample using SES (v5.40, also v5.30a nordic edition) it seems to build the project correctly (.elf, hex are generated)
But it throws error at the very end (screenshot attached) "Error starting process echo".
What's the significance of this and how to resolve this issue? Please advise.
I still couldn' t solve this problem. What shall I exactly do? I was not able to find the same files that is shown at the github commit.

This is what I did, that helped me build successfully (no "Error starting process echo" thrown)

That's it - no "Error starting process echo" for me now:) Hope this helps you too
Thank you very much, it worked! 
The patch correctly avoids the issue with failing echo, but it also change the print of the message.
OpenThread intends to print the text with each setting on a new line, like this:
OPENTHREAD_CONFIG_ASSERT_ENABLE=1
OPENTHREAD_CONFIG_BACKBONE_ROUTER_DUA_NDPROXYING_ENABLE=0
OPENTHREAD_CONFIG_BACKBONE_ROUTER_MULTICAST_ROUTING_ENABLE=0
OPENTHREAD_CONFIG_BORDER_AGENT_ENABLE=1
OPENTHREAD_CONFIG_BORDER_ROUTER_ENABLE=1
OPENTHREAD_CONFIG_ENABLE_BUILTIN_MBEDTLS=0
OPENTHREAD_CONFIG_ENABLE_BUILTIN_MBEDTLS_MANAGEMENT=0
OPENTHREAD_CONFIG_CHILD_SUPERVISION_ENABLE=1
OPENTHREAD_CONFIG_COAP_API_ENABLE=1
....
Whereas the attached patch will print `\n` instead of a new line, like this:
OPENTHREAD_CONFIG_ASSERT_ENABLE=1\nOPENTHREAD_CONFIG_BACKBONE_ROUTER_DUA_NDPROXYING_ENABLE=0\nOPENTHREAD_CONFIG_BACKBONE_ROUTER_MULTICAST_ROUTING_ENABLE=0\n...
when running CMake / ninja in a shell.
