Hi Snowuyl,

I have tried running the IPC_service sample in NCS v2.3.0, and will just copy here what I wrote to you in another case:

I tried to reproduce this issue, and ran into all sort of trouble. It turns out that the IPC service sample (and some others, I suspect), are completely broken on NCS 2.3.0.

I believe that earlier NCS versions worked, and I can confirm that NCS v2.4.0 works as well. Are you early enough in development that you could upgrade your NCS version to v2.4.0? I would strongly recommend it. I see that you have opened a lot of other IPC related cases as well, these might be resolved by that.

Best regards,

Raoul

Thanks for your reply! I have upgraded ncs from v2.3.0 to v2.4.0. The following issue has been solved by "west flash --recover" command.
