wchar_t Linker error with Open Bootloader example

[Aadishri GS]

I get the below linker error.

Error[Lt009]: Inconsistent wchar_t size
nrf_cc310_bl_ecdsa_verify_secp256r1.c.obj(libnrf_cc310_bl_0.9.12.a) and 9 other objects in libnrf_cc310_bl_0.9.12.a have wchar_t size 16 bits
app_error_weak.o and 106 other objects, some of them in dl7M_tlf.a and 13 other libraries have wchar_t size 32 bits
Error while running Linker

I went through some posts and found it to be an incompatibility with IAR 7 and 8 WBs.

I need a solution to this at the earliest. Kindly help

I have attached my build log

Hi,

The wchar size varies between toolchains. You can refer to the SDK release notes for details on which library binaries works with IAR 8 (search for "Note for IAR 8 users").
