Problem during Serialization of nRF52840

[Micha Valach]

Hello,

I have 2 PCA10056 DK (with nRF52840), my purpose is to check the serialization between App. chip to connectivity chip

I have 2 problems on in each chip:

1. App chip: - I'd like to compile the project \nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_hrs\pca10056\ser_s140_uart\iar\  (i'm using IAR 8.20.2) however I got linker error see below

ser_phy_uart.c
ser_sd_transport.c
ser_softdevice_handler.c
system_nrf52840.c
utf.c
Linking
Error[Lt009]: Inconsistent wchar_t size
ssi_aes.c.obj(libnrf_cc310_0.9.12.a) and 64 other objects have wchar_t size 16 bits
aes.o and 178 other objects, some of them in dl7M_tlf.a and 13 other libraries have wchar_t size 32 bits
Error while running Linker

Build aborted.

2. connectivity chip - seems something happens to the BL and Led5 is always off, and no D: drive is open - Please advise
i successfully compiled the connectivity chip project  

Please advise

Best Regards

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 - When building the project, you might get the warning: "The header file 'cmsis_iar.h' is obsolete and should not be used.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.)

Terje
