当我尝试编译时、收到以下错误：

../28003x_cla_flash_lnk.cmd“、第 158 行：错误#10099-D：程序无法放入可用内存中、或者该段包含一个需要无法为该段生成的蹦床函数的调用站点。对于“Cla1Prog"段“段（大小为 0x3510 第 0 页）、带对齐/分块的运行放置失败。可用存储器范围：
RAMLS4_5_6 大小：0x1800 未使用：0x1800 最大孔：0x1800

报告的 THS 大小 (0x3510) 是 CLATask8 的位置、大小应约为 0x1300。

在采用 C2000W2_00_00_02 和较旧版本编译器的 280049 处理器上、代码运行正常。我无法在当前安装的 C2000Ware 和编译器上编译旧代码。

感谢您的帮助。
