Bootloader merging fails with:

Merging Regions

This fails two times, and third retry in compilation passes.

There was this fix but caused some other failures https://github.com/ARMmbed/mbed-os/pull/8788, reverted via https://github.com/ARMmbed/mbed-os/pull/8915

This is not a regression caused in the recent hours? I've reviewed the logs, not much landed to tools in the last days

I tested this with Mbed OS from last friday, and this morning.

Hi @teetak01 I wasn't able to reproduce this, here's my environment:

Windows 10
Mbed CLI 1.9.1, installed on python 3.6.3
Hash for mbed-cloud-client-example-internal: 991357060e45569393ded95d6dc37b4f438df3f2
Hash for mbed-os: 31da50e8fa68a2bbe8c92d70b258a5d19a41b5e3
Command: mbed compile -m K64F -t ARMC6

Do you have a setup that reproduces the issue consistently?

[cmonr]

@bridadan Sanity check. Could you retry the previous command with -v and -vv?

Iirc, I came across this problem last week (was retesting this: https://github.com/ARMmbed/mbed-os/issues/8146#issue-360754864), and this odd behavior led me to opening https://github.com/ARMmbed/mbed-os/issues/9675

[theotherjimmy]

@cmonr That was related to the time stamp, so running with -v was eliminated as the cause.

[bridadan]

(for completeness I ran it with -v and -vv, no change)

[teetak01]

@bridadan Ubuntu 18.04.1, Python 3.6.7, fresh installation. Happens quite reliably on my setup.

[teetak01]

Also happens with GCC 6.3.1

[bridadan]

I had a spare moment to setup an Ubuntu VM. I am able to reproduce the error!

[bridadan]

This one was a quick fix once I had that reproducible case. Here's the PR: https://github.com/ARMmbed/mbed-os/pull/9783/files
