As for device support, this is good to go. Tested locally.

uVision was hanging again, had to kill it.

IAR made it through though. NRF52_DK and DELTA_DFBM_NQ620 both had failures similar to this:

10:49:31 C:\Jenkins\workspace\exporter_build_test\ide\iar\cmsis\core_cm4.h(1753) : Error[Ta097]: Cannot call intrinsic function "__nounwind __DSB" from Thumb mode in this architecture

10:49:31 Error while running C/C++ Compiler

Any ideas @sarahmarshy?

@0xc0170 You were able to get this working locally? Did you have to do any extra steps?

No extra steps. Tested with blinky, builds fine for me. This was this labeled ready for merge

What version of IAR are you using? CI uses 7.40

[bridadan]

Just tried it locally with IAR 7.70, looks like that was the issue. I'll need to update the CI machines to use this version. I'll try to do this tonight if at all possible and get another run in.

What is for review here? What's outstanding?

@bridadan Are those errors in the failure (iar build failures) known or new?

[bridadan]

@0xc0170 I'm trying to get the CI machines upgraded to IAR 7.70 for exporters so we don't lose the ability to run the exporter tests. I'm hoping I've got it all taken care of now, running again.

Had to kill uvision because it was hanging, but IAR was all passing, so LGTM 👍
