Using pelion without internal storage

Hello.
I try to modify pelion-ready-example on NUCLEO_F746ZG target to use without an internal flash storage.
To reach my goal I try to set external secure storage feature:

"mbed-cloud-client.external-sst-support": 1

After that I get compilation error:

./simple-mbed-cloud-client/mbed-cloud-client/mbed-client-pal/Source/Port/Reference-Impl/OS_Specific/mbedOS/ROT/pal_plat_rot.cpp:67:5: error: 'DeviceKey' was not declared in this scope

[Here] (https://github.com/ARMmbed/mbed-os/issues/10876) I found solution and add FLASHIAP component:

"target.components_add" : ["FLASHIAP"],

Now it seems that internal flash is required again.
More over is correct compiled but fail on client initialization:

Is it possible to use pelion without using internal flash? And how I can make it?

Hi @SlavaDev503
Thank you for your question!

Unfortunately, I don’t have the device to reproduce, however, from the logs and code, I see that you get a failure from sotp_init, when internally it tries to erase internal flash.
As you can see from the code , the sotp_init() should not even be called if MBED_CONF_MBED_CLOUD_CLIENT_EXTERNAL_SST_SUPPORT is defined, which it should be defined, since you configured mbed-cloud-client.external-sst-support. Probably because of dependency between sotp and internal flash.
Please try updating your simple-mbed-cloud-client version as it seems that you are working on an old version.
in addition, I would suggest checking that MBED_CONF_MBED_CLOUD_CLIENT_EXTERNAL_SST_SUPPORT is in fact defined in your target’s mbed_config.h file

Ron, thank you for your response.
It seems that I send invalid log.
Actualy I get another error.

Hi Slava,
It is not clear to me what verision of the application you are working on.
With your mbed_app.json I get compilation errors, once of them is redefinition of MBED_CLOUD_CLIENT_UPDATE_STORAGE for example
