Starting CI to confirm PR was part of the problem, and to give the other @ARMmbed/mbed-os-maintainers a path forward since it's pretty late over here.

CI started

What problems were caused by #9092?

[0xc0170]

I believe a new target came in about the same time. #9232 this could be it, we need to find failures in the latest CI runs, will check

[0xc0170]

Found it, http://mbed-os-ci.s3-website-eu-west-1.amazonaws.com/?prefix=jenkins-ci/artifacts/9203/3/build-ARM/FAIL/

I also noticed that new target has been added just before #9092. If this is the case I can create a PR with updated linker scripts for the added target.

Great! I'll create a PR with fix for these two targets.

I aborted the test, build passed means this would fix it but we rather fix it properly soon

[mbed-ci]

Test run: FAILED

Summary: 1 of 11 test jobs failed
Build number : 1
Build artifacts

Failed test jobs:

• jenkins-ci/mbed-os-ci_greentea-test

[0xc0170]

Aborted the job (CI machine restart needed), anyway there is already a fix

[cmonr]

@mprse Whoops! Should've provided more direct links to the failures.
Glad you were able to fix it.
