28035的CLA在FLASH里不能起动-TI中文支持网

TI的专家你们好，请教一个问题：28035的CLA在有仿真情况下，运行正常；去掉仿真器后，自起动却不行，通过输出，确信CAL也运行。但电机却没有反映。网上有贴说加了

CLA1mathTables : LOAD = FLASHB, /*指定加载地址*/
RUN = CLARAM1, /*指定运行地址*/
LOAD_START(_Cla1TablesLoadStart),
LOAD_END(_Cla1TablesLoadEnd),
RUN_START(_Cla1TablesRunStart),
PAGE = 1

就可以，我也加了，依然没反映。请教一下如何解决？下面是我的CMD文件（文件来自：\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.1\HVPM_Sensorless_CLA_F2803x）

Eric Ma：

教一个问题：28035的CLA在有仿真情况下，运行正常；去掉仿真器后，自起动却不行，通过输出，确信CAL也运行。但电机却没有反映。

ERIC:

你说仿真能够运行，仿真的时候，也是运行在FLASH吗？GPIO34, GPIO37有没有上拉或是悬空。

既然你用的是F28035，我倒是建议你直接跑一下这个例程，或用这个例程去做对比，因为这个例程是可以工作的。
