利用2812烧写了一个程序，其中CMD文件主要内容如下：<br />MEMORY<br />{<br />PAGE 0 : <br /> OTP : origin = 0x3D7800, length = 0x000800<br /> FLASHJ : origin = 0x3D8000, length = 0x002000<br /> ....<br /> FLASHA : origin = 0x3F6000, length = 0x001FF6<br /> BEGIN : origin = 0x3F7FF6, length = 0x000002<br /> PASSWDS : origin = 0x3F7FF8, length = 0x000008<br /> ROM : origin = 0x3FF000, length = 0x000FC0<br /> VECTORS : origin = 0x3FFFC2, length = 0x00003E<br />PAGE 1 : <br /> /*SARAM*/<br /> ....<br />}<br />SECTIONS<br />{<br /> /* Allocate program areas: */<br /> .reset : > BEGIN PAGE = 0<br /> vectors : > VECTORS PAGE = 0<br /> .cinit : > FLASHJ PAGE = 0<br /> .text : > FLASHA PAGE = 0<br /><br /> /* Allocate data areas: */<br /> .stack : > RAMM0M1 PAGE = 1<br /> .bss : > RAML0L1 PAGE = 1<br /> .ebss : > RAML0L1 PAGE = 1<br /> .const: load = FLASHB PAGE 0, run = RAML0L1 PAGE 1<br /> {<br /> /* Get Run Address */<br /> __const_run = .;<br /> /* Mark Load Address*/<br /> *(.c_mark)<br /> /* Allocate .const */<br /> *(.const)<br /> /* Compute Length */<br /> __const_length = .-__const_run;<br /> } <br /> ....<br />}<br />这样一来，程序应该就是在FLASH中运行吧？<br />反正烧写完后重新运行的话，其中的外部AD采集就出乱码了，而在仿真情况下是没问题的。所以应该要把程序拷贝到RAM运行吧？<br />请问如何来实现呢？是否也可像.const那样Load Run就能实现？ |
