器件型号：TMS320F28377S 各位专家、您好！
我正在向我们的客户提出此问题。
客户使用 TMS320f28377S、CCS 版本和编译器版本如下图所示。
客户发现、当分配未初始化的数据时、如果.ebss、.esystem、.cio 和.data 分配的地址包含0x10000之后的地址、则程序无法运行、并且在调试后将显示下图。
例如、在下图中、.ebss、.esSystem,.cio 和.data 被分配到0x10000之前的地址、可以正常调试。
例如、如果下图中的.ebss、.esystem、.cio 和.data 分配给0x10000之后的地址、则会发生上述问题。
由于我没有 F28277S 的 EVM、因此我使用 F28379D 进行测试、无法重现客户的问题。 我注意到 CIO 显示在控制台表的左上角。 这是否是.cio 分配问题？ 请帮我分析一下。 我要在下面附上客户的.cmd 文件
// The user must define CLA_C in the project linker settings if using the
// CLA C compiler
// Project Properties -> C2000 Linker -> Advanced Options -> Command File
// Preprocessing -> --define
#define CLA_C
#ifdef CLA_C
// Define a size for the CLA scratchpad area that will be used
// by the CLA compiler for local symbols and temps
// Also force references to the special symbols that mark the
// scratchpad are.
CLA_SCRATCHPAD_SIZE = 0x200;
--undef_sym=__cla_scratchpad_end
--undef_sym=__cla_scratchpad_start
#endif //CLA_C
