Recently i was trying to develop example with IAR 8x

[toamrit]

i have read it from a resource that 7.80.4 will support can anyone help me with IAR 7.80.4 setup trial to check the feasibility for development

Hi,

We support IAR in nRF5-SDK. www.nordicsemi.com/.../nRF5-SDK

For nRF5-SDK v17.1.0, we used  IAR 7.80.4

For IAR 8, you need to do some modifications to the SDK:

Note for IAR 8 users:

When using IAR 8, you must apply the following workaround in the MDK:

- Apply a patch to modules/nrfx/mdk/compiler_abstraction.h at line 140
 (fix the '__ALIGN()' macro definition): use the argument 'n' in the macro expansion instead of 'x'.

-------------------

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 instructions:
 1. Open the IAR project in IAR 8. The IAR workbench will automatically generate an IAR 8 compatible project file.
 2. 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).
 3. Save the project.
 4. When building the project, you might get the warning: "The header file 'cmsis_iar.h' is obsolete and should not be used.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: https://devzone.nordicsemi.com/f/nordic-q-a/31123/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 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”.
