/* Define the memory block start/length for the F2806x
PAGE 0 will be used to organize program sections
PAGE 1 will be used to organize data sections

Notes:
Memory blocks on F28069 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.

Contiguous SARAM memory blocks can be combined
if required to create a larger memory block.

求各位同行指导啊

需要的话，我把MAP文件也贴上来

Seven Han：

The solution presented allows designers to copy initialized compiler sections (.text, .cinit, .econst, .switch,etc.) from the Flash to RAM at runtime to allow maximum execution speed.

应该是GROUP为没有初始化的变量，不可以link到flash，应该link到RAM。
