程序很短，把flash的程序全部搬移到ram中运行。
.stack : > RAMM0 PAGE = 1
.ebss : > RAML4L5L6L7 PAGE = 1
.esysmem : > RAMM1 PAGE = 1
.text : LOAD = FLASHA, PAGE = 0
RUN = RAM_L0L1L2L3, PAGE = 0
LOAD_START(_text_loadstart),
RUN_START(_text_runstart),
SIZE(_text_size)
上面这个RAM_L0L1L2L3是程序空间，定义成 : origin = 0x008000, length = 0x006000
RAML4L5L6L7 是数据空间定义成 : origin = 0x00E000, length = 0x002000
现在发现这个程序烧写在部分板子中是能正常运行的（观察中断 toggle的呼吸灯），但是有些板子中，上电后怎么都不能正常运行（呼吸灯不闪），连上仿真器能看到是进了illegal_isr了，有些板子用硬件狗TPS3828-33DBVT复位多次后，程序又能正常运行了，开始以为是硬件电路的问题。
但是我更改上面程序空间和数据空间的分配后，不能正常的板子也可以一上电就能跑起来，但是另一些本来好着的板子又不能运行了，这样感觉好像是cmd的问题，我查看map，.txt 等分配都是没有超范围的。请专家帮我分析分析，万分感激！
