thingy91 serial lte modem flash memory issue

[hamit]

Hi,

I am trying to open serial lte modem app to evaluate power profile on thingy91.  i am using toolchain manager (v1.4.99-dev1) to open Segger Embedded Studio.

While building the solution, I am having an error as below:

1> Memory region Used Size Region Size %age Used

Build failed

ı tested with nrf9160dk and it is ok.

Am i missing something ?

The issues you are seeing should be fixed with PR 4103 though. Let me know if it doesn't.

Best regards,

It is great! Thanks very much Simon.

After the relevant changes on spm, now i am able to build the slm app.
