Hi Jack Porter,

[quote user="Jack Porter"]Has this issue ever been resolved ?[/quote]

Yes. See the section "Note for IAR 8 users" found in the Introduction for SDK 16.

Hi, I'm having the same problem in January 2020. IAR 7 is not an option, my company uses IAR 8. Has this issue ever been resolved ?

Is using IAR 7 an option for you?

Hi,

SDK 14.1 uses IAR Workbench 7.80.4 for testing and verification. IAR 7.x uses 16 bit wchar_t, but IAR 8.x uses 32 bit wchar_t. More information about this from IAR can be found here.

The SDK contains precompiled libraries, some of which are not open, which are built using IAR 7 with the wchar_t size of 16 bits. Since IAR 8 uses wchar_t size of 32 bits, there is a mismatch between the precompiled libraries and the newly compiled project code, and the build fails. SDK 14.1 is therefore not fully compatible with IAR 8.
