Hi everyone,

First of all basic information about CPU,etc:

1. Which embOS do you use?

2. Which CPU and eval board do you use?

CPU: ATSAMV71Q21
Board: Atmel SAM V7 Xplained Ultra Evaluation Kit

3. Which start project do you use?

Package:
embOS_CortexM_IAR_V6_Trial_V412a.zip
Start project: Start_SAMV71.eww

4. What compiler do you use ?

When I compile the project I get the following message:

Hi Stephan,

I just did a quick check with IAR EWARM V7.30.4 (I don't have V7.30.1 installed) and it builds w/o any warnings or errors.
The project was built for the IAR ARM Compiler 7.30.4.

The linker error message occurs because we rename some functions like OS_InitKern() in order to avoid that an embOS Cortex-M library with FPU support is being used in a project without FPU support.
Your linker searches for "OS_InitKern_STD" which is part of the non FPU library but the start project contains the embOS Cortex-M library with FPU support (os7m_tlv_dp.a).

This could happen when not the correct core/device is selected in the project options.
Could you please check if the correct core/device and FPU settings are still selected in the project options?
You could also use IAR EWARM V7.30.4, of course.

Best regards,
Til

Hi,

thanks for your quick response !
I updated my IAR to version 7.5.1 and I was able to compile it without error.
