/* ======================================================
// For Code Composer Studio V2.2 and later

// In addition to this memory linker command file,
// add the header linker command file directly to the project.
// The header linker command file is required to link the
// peripheral structures to the proper locations within
// the memory map.
//
// The header linker files are found in <base>\DSP2803x_Headers\cmd
//
// For nonBIOS applications add: DSP2803x_Headers_nonBIOS.cmd

/* Define the memory block start/length for the F2803x
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/L1/L2 and L3 memory blocks are mirrored - that is
they can be accessed in high memory or low memory.
For simplicity only one instance is used in this
linker file.
Contiguous SARAM memory blocks can be combined
if required to create a larger memory block.

楼主
。这是不是很多都自己开发bootloader的原因吧
