C6748编译错误

之前一直在做UDP协议，用的是CCS V7.2，库用的是ndk_2_20_06_35，然后我把Output type从eabi(ELF)变成legacy COFF,把Compiler version从TI v8.2.2变成TI v7.4.24，因为只要把Output type格式改了,complier version版本就不兼容TI v8.2.2了，所以我把Complier也改了，然后编译就出现了如下错误

请问怎么解决呢？

Shine：

在工程属性->General->RTSC->SYS/BIOS->Target选择ti.targets.elf.C674 试试

Ryan BL：

记得之前翻ti的release note的时候有看到，ndk2.20还没支持elf，2.24才开始支持的吧。so，要么升级ndk/bios，要么使用老的coff。
