Build for *_boot target fails with AddressOverlapError: Starting addresses are different

[vkolotov]

Hi All,

I'm trying to build my projects locally with mbed-cli tool for a *_boot target. I can do this successfully via online compiler, but mbed-cli fails with "AddressOverlapError: Starting addresses are different".

I'm also able to build for *_ota and just without any postfixes, e.g.:

mbed compile -t GCC_ARM -m nrf51822_ota -c

and

mbed compile -t GCC_ARM -m nrf51822 -c

Here are some details:

mbed compile -t GCC_ARM -m nrf51822_boot -c -v

....

Am I doing something wrong?

@vkolotov Have you been able to find solution to your question?

I'm having the same issue.
Reproduces using the ble_led example with command
mbed compile --target NRF51_DK_BOOT --toolchain GCC_ARM -v

results in:

[DEBUG] SoftDevice file found s130_nrf51_1.0.0_softdevice.hex.
[DEBUG] Bootloader file found s130_nrf51_1.0.0_bootloader.hex.

AddressOverlapError: Starting addresses are different

This happens after I fixed bug ARMmbed/mbed-os#6835

Using mbed-cli 1.5.1 on Mac OS

@screamerbg I can reproduce this issue. I'll look into it while I'm thinking about it.

[melvinvdb]

Changing binh.merge(blh) to binh.merge(blh, overlap='replace') in mbed-os/tools/targets/__init__.py seems to solve this issue.
It is kind of weird because the hex files do not overlap (checked in hex editor).

[theotherjimmy]

@melvinvdb Yeah, it might be that both files have a start address, which will conflict and generate overlap errors.

@theotherjimmy What's the conclusion on this? Can we close the issue here?

[theotherjimmy]

I'll make the PR to add that change to the nordic post-build script.
