Mbed-os: Error at compile MCC app with K64F bootloader

[MarceloSalazar]

Description

Evaluating 5.10 (RC2) and the Pelion device management feature with mbed-cloud-client-example-sources-internal app (sorry internal only).

I'm seeing an error at the last step of the compile process (merge with bootloader)

mbed import mbed-cloud-client-example-sources-internal
cd mbed-cloud-client-example-sources-internal
mbed update 2.0.0-RC2
<CLOUD_SDK_API_KEY already set>
mbed dm init -d "arm.com" --model-name "mbed" -v -q --force
mbed compile -t GCC_ARM -m K64F -c -v
...

This makes me think there is a problem with the bootloader, the tools or the app.

@theotherjimmy @teetak01 can you please have a look and comment?

[teetak01]

I am unable to reproduce this. Might this be related to specific pip components versions or did you do any changes to mbed_app.json? I tested with python-sdk 2.0.0 and 2.0.1

[MarceloSalazar]

I can't reproduce on Win7 / Python2.7.
Maybe a problem with Python 3?

[MarceloSalazar]

I'm able to reproduce this on Windows 10 as well with Python 3.6.5

I am able to reproduce this on Windows 10 with Python 3.6.3:

This was fixed last year in 5.10.2 (tried it locally to confirm): https://github.com/ARMmbed/mbed-os/pull/8330
