DA14531 - Codeless with IAR


I'm making a project with DA14531, and I'm using the source code given in the CodeLess documentation. I'm trying to convert the code fromKeil5 to IAR EW for ARM 8.50.9. I think I made all the pertinent changes to the project, but when I try to build it, I get the following error:

I'm using the same linker provided inside the plox_reporter from ble_examples from SDK Is there any changes that I need to make and I'm not paying attention to?
