Hello,
I noticed the linker file we were using was for the nRF52832_xxAA so I got the nrf52832_xxab.icf from C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.0\arm\config\linker\NordicSemi\nrf52832_xxab.icf.
After switching linker files IAR fails the linking stage with the following error: Error[Lc041]: "block PROC_STACK" defined but not referenced nrf52832_xxab.icf 74
The new linker file: nrf52832_xxab.icf
Are the linked files included with IAR correct?
Look forward to hearing from you, James
