TI中文支持网我现在使用F28075,启用了加密功能。将所有的fiash；CLA；RAM:D0,D1,LS0~LS5都分配到Zone1，加密上锁。LS0~LS5分配给CLA，所有的数据（cla会读写的数据放置在LS0）、堆栈等都分配到除上述区域外的片上RAM，将“ramfuncs”代码段（如ADC中断函数代码）上电从flash复制到RAMD0D1中运行，一切正常。现在我想把CAN发送函数代码从flash复制到非安全RAM GS1中去运行，以提高其运行速度。CAN发送函数中没有调用“ramfuncs”代码段的函数，调用的函数也都分配到RAM GS1中。CAN发送采用定时器0中断来执行，定时器0中断函数也分配到RAM GS0中，然后执行，发现CAN没有发送数据。这些函数没有分配到RAM GS1，直接在flash里运行时，一切正常。
我想了解一下，像我这样对芯片加密后，GS1是不是不能加载代码运行？下面是cmd文件：
// Set this variable to 1 to use the CLA Math Tables in the CLA Data ROM
// If set to 0, make sure the right CLA Math library is used in the project
–define=CLA_MATH_TABLES_IN_ROM=1
_Cla1Prog_Start = _Cla1funcsRunStart;
-heap 0x100
-stack 0x100
// 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 = 0x100;
–undef_sym=__cla_scratchpad_end
–undef_sym=__cla_scratchpad_start
