TMS570LS0914：在使用Fapi_BlockErase擦除flash的时候卡死？

目前在执行Fapi_BlockProgram( 0, addr, (uint32_t)data, 4); 语句卡住，测试地址为0x000FFC00。

发现是卡在while( FAPI_GET_FSM_STATUS!= Fapi_Status_Success );但是之前我们在TMS570LS1224开发板上测试是OK的，用同样的程序在TMS570LS0914上测试就会卡死，不知道这两者的芯片有什么区别？

Susan Yang：

请问您的flash API的版本是多少？不同的版本，用法略有差异。

是否enable了您准备擦写的sectors：

Fapi_enableMainBankSectors(0xFFFF);

另外当代码也在同一个bank运行时，您无法erase/programflash bank 。这时您需要在RAM内运行 Flash API

回复 Susan Yang:

我这个代码是从网上找的，我也不知道这个版本是多少，你能告诉我哪里能看到版本吗？

目前我擦除的是0扇区，在擦除前使用了Fapi_enableMainBankSectors(0xFFFF);或Fapi_enableMainBankSectors(0);还是一样会卡死

另外，我把Flash API相关函数都是放到RAM中运行的（这个是保证的）

并且我仿真发现while(FAPI_GET_FSM_STATUS != Fapi_Status_Success);这个寄存器一直返回0x810，目前所使用的的代码原型如下：
