大家好,我使用的C6748,在sysbios debug时出现了Loop buffer exception,具体信息如下:

Loop buffer exception
Missed stall exception

xdc.runtime.Error.raise: terminating execution
请问如何定位这个问题出现在哪?同样的程序有时候debug没事,有时候就会出现Loop buffer exception,请问怎么解决
你好,请问是这样加入编译选项吗?我看提示貌似不对..会忽略加入的选项
-mv6740 --abi=eabi -g --include_path="../code_user" --include_path="${CG_TOOL_ROOT}/include" --include_path="${COM_TI_UIA_INCLUDE_PATH}" --include_path="C:/ti/C6748_StarterWare_1_20_04_01/include" --include_path="C:/ti/C6748_StarterWare_1_20_04_01/include/hw" --include_path="C:/ti/C6748_StarterWare_1_20_04_01/include/c674x/c6748" --define=${TI_MATHLIB_C674X_SYMBOLS} --define=${TI_MAS_DSPLIB_C674X_SYMBOLS} --define=${COM_TI_UIA_SYMBOLS} --define=${BIOS_SYMBOLS} --define=c6748 --display_error_number --diag_wrap=off --diag_warning=225 --diable:sploop
确定之后提示invalid compiler option --diable:sploop (ignored)
