// For Code Composer Studio V2.2 and later
// ---------------------------------------
// In addition to this memory linker command file,

// the memory map.
//
// The header linker files are found in <base>\DSP2803x_Headers\cmd
//
// For BIOS applications add: DSP2803x_Headers_BIOS.cmd
// For nonBIOS applications add: DSP2803x_Headers_nonBIOS.cmd
========================================================= */
/* ======================================================
// For Code Composer Studio prior to V2.2
// --------------------------------------
// 1) Use one of the following -l statements to include the
// header linker command file in the project. The header linker

// locations within the memory map */

/* Define the memory block start/length for the F28035
PAGE 0 will be used to organize program sections
PAGE 1 will be used to organize data sections
Notes:
Memory blocks on F2803x are uniform (ie same
physical memory) in both PAGE 0 and PAGE 1.
That is the same memory region should not be
defined for both PAGE 0 and PAGE 1.
Doing so will result in corruption of program
and/or data.
L0 memory block is mirrored - that is
it can be accessed in high memory or low memory.
For simplicity only one instance is used in this
linker file.
Contiguous SARAM memory blocks or flash sectors can be
be combined if required to create a larger memory block.

上电后bootloader程序接收到上位机升级命令，就准备升级接收Appro的十六进制代码，然后flash擦除写入。一次擦除一个扇区8K，写满16次512字节，再擦除再写。写完后，绝对地址函数跳转到Appro软件CMD定义的起始地址。
上位机也是自己用labview 写的，通过仿真，数据都是写入到了flash里面，函数也跳转了。但为什么跳转回就没有反映了，我Appro程序里，再次初始化串口，问题应该不大吧。怀疑是CMD文件不对，也不清楚那里不对，都是参照网上资料做的。现传上来请大神检查下。
还有boot程序里，做了如下才做，应用程序再做会冲突吗?如下。
InitSysCtrl();
DINT; //Disable CPU interrupts
InitPieCtrl(); //Initialize PIE control registers to default state
IER = 0x0000; //Disable CPU interrupts
IFR = 0x0000; //Clear all CPU intrrupt flags
InitPieVectTable();
/*****************/
memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (Uint32)&RamfuncsLoadSize);
Sci_Init();
由于CMD文件无法上传，扩展名改成了txt格式文件。
CMD参考附件F28035_flash_Boot.txt 和F28035_flash_App.txt
