RE: Problem during Serialization of nRF52840

Hi,

The nRF5 SDK v15.3.0 release notes contains the following note for IAR 8 users:

*****
Note for IAR 8 users:
(Libraries for IAR 8 require wchar_t to be of size 32 bits while IAR 7 requires 16 bits).

To run a project using IAR 8, follow these intructions:
- Open the IAR project in IAR 8. The IAR workbench will automatically generate an IAR 8 compatible project file.
- If the project contains one of the precompiled libraries listed below, replace it with the IAR 8 compatible alternative
   (there are no projects targeting nRF51 in this SDK).
- Save the project.
- When building the project, you might get the warning: "The header file 'cmsis_iar.h' is obsolete and should not be used. [...]".
    - The problem is described in DevZone post: devzone.nordicsemi.com/.../iar-ewarm-8-22-1-complains-about-cmsis_iar-h
      The solution is to remove all occurrences of #include <cmsis_iar.h>.

The affected libraries are:
- micro-ecc crypto:
    - IAR7: Includes library located in the folder named “…_iar\…”.
    - IAR8: Switch to using the library from the folder named “…_armgcc\…”.
- nrf_cc310, nrf_cc310_bl, and nrf_oberon:
    - IAR7: Link to a library where “short_wchar” is part of the folder name.
    - IAR8: Link to a library without “short_wchar” in part of the folder name.
- Gazell, NFC Tag, and 802.15.4:
    - IAR7: Includes the library where the file name ends with “_iar”.
    - IAR8: Switch to using the library with similar file name that ends with “_gcc”.
*****

Similar notes apply for other nRF5 SDK v15.x.x versions. Older versions of the SDK is only supported in IAR 8.10 and earlier (which was when wchar_t was changed in IAR.)

Regards,
Terje

Hello,

I was able to solve my 2'nd problem (by upload the J-Link OB-SAM3U128-V2-NordicSemi 170724.bin file to BOOTLOADER drive)

Please refer to my 1'st issue - related compile and linking using IAR 8.20.2
Thanks In Advance,
