那你检查程序

只要能烧写进去,就说明烧写没问题

请您详细描述跑不对的现象?
请检查 1. Delay_us();函数是否已经copy到内部Ram中运行。 2. 程序是否真的已经启动了? 例如用一个点灯程序确认 3. 请检查几个上电的Boot引脚是否都已经上拉。(内部已经上拉,只要你在PCB上没有下拉就好) 如果您认为此问题已被解答,请在“这是否解答您的问题” 后,点击“是”按钮! 谢谢您的合作! |

点灯程序已经有,灯没量,是在中断中作的。 Delay_us();函数是否已经copy到内部Ram中运行(怎么作,是不是memcopy?)确实有用到Delay_us(),但不知道是否拷贝进了ram。 引脚现在全部都没接,量过了也都是高电平。 |

那请您先将程序烧写到Flash中,在Flash中,进行调试试试。不要断掉仿真器。 File->Load Symbols->Load Symbols Only->选择你的.out文件。 看看这样运行是否停止到了 Ilegal ISR中的。 再单步查询具体哪一步导致进入了illegal ISR。 如果您认为此问题已被解答,请在“这是否解答您的问题” 后,点击“是”按钮! 谢谢您的合作! |

www033 发表于 2018-6-11 05:07 连接仿真器,在闪灯中断中设置断点,发现可以正常显示。 于是断开仿真器,发现没有反应。 下面是我的配置文件 /* // TI File $Revision: /main/9 $ // Checkin $Date: August 28, 2007 11:23:38 $ //########################################################################### // // FILE: F28335.cmd // // TITLE: Linker Command File For F28335 Device // //########################################################################### // $TI Release: DSP2833x Header Files V1.01 $ // $Release Date: September 26, 2007 $ //########################################################################### */ /* ====================================================== // For Code Composer Studio V2.2 and later // --------------------------------------- // In addition to this memory linker command file, // add the header linker command file directly to the project. // The header linker command file is required to link the // peripheral structures to the proper locations within // the memory map. // // The header linker files are found in // // For BIOS applications add: DSP2833x_Headers_BIOS.cmd // For nonBIOS applications add: DSP2833x_Headers_nonBIOS.cmd ========================================================= */ /* ====================================================== // For Code Composer Studio prior to V2.2 // -------------------------------------- // 1) Use one of the following -l statements to include the // header linker command file in the project.

另外,我的的第一个CodeStartBranch是没有加入到编译里来的,因为一加进来就报错了:pinit和cinit没定义,明明定义了,会不会是这里有问题? |
