28377D/S有没有其他办法(除了TI提供的)把程序固化在flash里面然后复制到RAM里面运行。-TI中文支持网

正在用28377D这颗芯片，发现TI提供的把程序放在FLASH里面的办法太啰嗦了，然后我按照28335进行了改进，CMD文件如下：

然后用memcpy把.text .cinit 等section复制到RAM中，但是我发现不能正常运行，这样做运行出来的程序与放在RAM里面的程序接受的IO数据不一样，真不知道该怎么办了，这颗芯片TI也没有提供完善的驱动和程序，真心难用。

Eric Ma：

TI 在controlSUITE中有提供完善的驱动例程啊，都八个版本了，汗。

C:\ti\controlSUITE\device_support\F2837xD\v190

另外，你把.text段都复制到RAM，谁来执行memcpy的函数呢？？只有调用memcpy，才能去调用复制到RAM的函数。其他段类似。

建议你参考例程中的initflash函数，这是标准的copy做法。
