Atmel studio 7:无法识别的选项`-mrelax‘

Question

我从Atmel Studio提供的Example Gallery下载了freeRTOS Basic example -EVK1100，并尝试构建它，得到以下错误

recipe for target 'src/asf/avr32/utils/startup/trampoline_uc3.o' failed 

构建输出给出了：

我相信链接器会抱怨option -mrelax`unrecognized option -mrelax。This reference显示我必须检查relax分支，但在我的版本中找不到该选项

我想知道是否有一个补丁应用到我的链接器，以便它可以识别这个选项，或者选中/取消选中项目文件中的一些选项，或者...

我正在使用

Atmel Studio 7(版本7.0.934)

Windows 10

提前感谢
