你好，我是用的 F021 FLASH API （02.01.01）进行flash调试的。

其中，Flash Bank Sector Enable Register (FBSE) =  0x00000400；Flash Bank Protection Register (FBPROT) = 0x00000001;

下面图1为写FLASH的代码：

图2为擦FLASH的代码：

请问哪里配置还有问题吗？flash上电部分地址有数是正常现象吗？有数的地方应如何擦除呢？

找了个开发板测试了一下，如下图

板子内有预设的程序，所以flash内是有数据的

之后使用uniflash进行擦除

擦除后如下图所示

我们现在是这样的，我们的程序通过仿真器直接下载到芯片FLASH的bank0了，从bank0的起始地址到bank0的某某地址为我们的代码，这部分地址有数据我理解，但是除了代码地址段，其他地方也随机分布着一些数据，而且我现在是要通过烧录的代码去操作bank1，bank1一上电它里面的数据是下图这样的，并不是全FF，bank0的非代码区也并不是全FF，这种现象是否正常？

你好，你开发板芯片型号是TMS570LS43X系列，我用的芯片是TMS570LC43X系列的，这有区别吗？
