关于代码在SDRAM中运行问题请教

xiaobakang

我根据火哥关于代码在SDRAM中运行代码的ICF的配置，根据自己的工程进行了更改，但出现了问题。

具体问题是：我配置好ICF后，编译工程，在开始Link时出现如下错误：
Error[Lc036]: no block or place matches the pattern "zi section .bss in bsp_spi.o symbols: [lpspi3_config]"
Error[Lc036]: no block or place matches the pattern "rw data section .data in bsp_fonts.o symbols: [Array_ACConst]"

Error[Lc036]: no block or place matches the pattern "rw data section .data in bsp_fonts.o symbols: [gImage_font1_d5]"

.
.
.
.

等等101个错误。

1. 以下是我的ICF的配置

2. 我的程序的代码量：

224 663 bytes of readonly code memory

866 211 bytes of readonly data memory

7 990 982 bytes of readwrite data memory

3.我的几点理解：

1.代码复制到SDRAM中运行是不是就把代码当做RW类型来处理了。

2.我根据程序的代码量设置了RW ZI 的大小 分别是：

/* SDRAM code */

define symbol m_ram_text_start = 0x80000400;

define symbol m_ram_text_end = 0x81CFFFFF;

。。。

define symbol m_data3_start = 0x81D00000;

define symbol m_data3_end = 0x81DFFFFF;

但最终编译还是出问题，所以请教下。。。

这个配置好复杂 ，建议还是先用火哥的配置 文件

用的就是火哥的配置文件。已解决。谢谢！

SDRAM_TEXT_region区域定义的有点小，我的程序加载了很多图片。
