@nvlsianpu Is debugging supposed to work on IAR with nRF52840-xxAA devices ?

It is supposed to work, as it is similar to nRF52832.

@nvlsianpu The CI failed: 17:26:50 C:\mj\workspace\bm_wrap\206\examples\mbed-os-example-blinky\mbed-os\cmsis\core_cm4.h(1600) : Error[Ta097]: Cannot call intrinsic function "__nounwind __DSB" from Thumb mode in this architecture This is for IAR, and this new platform.

[0xc0170]

Can you have a look at the failure?

[nvlsianpu]

I will do this.

@0xc0170 Please check whether you installed proper MDK for IAR (8.11.1 or newer). Link for install setups: http://www.nordicsemi.com/eng/nordic/Products/nRF52840/nRF5x-MDK-IAR/58863

That would explain it. Is this captured anywhere what version is required ?

@bridadan Please can you check if that this MDK is installed in the CI?

[bridadan]

@0xc0170 @nvlsianpu We are still currently using IAR v7.80. Does the NRF52840 support that version of IAR?

@bridadan

We are still currently using IAR v7.80. Does the NRF52840 support that version of IAR?

Yes. Even older one would work. Only nRF5x-MDK-IAR is required.

[0xc0170]

@nvlsianpu CAn you please capture it in the commit message what is required to have (>thisversion at least must be installed) ?

@bridadan Please restart CI once it is installed in the CI, thank you

[bridadan]

@nvlsianpu Thanks for the tips! All the machines should have this installed now.

@bulislaw Can you have a look at the report above? It pinpoints to core_cm4 header file (the virtual nvic inclusion that was added recently) ?

[bulislaw]

The virtual header file points to cmsis_nvic.h and it only influences NVIC functions. Question: Was it ever working? If it was maybe it's an easy bisect.
