一、把STM32F103大容量移植到STM32F103C8T6上的步骤：
1、换启动文件
startup_stm32f10x_cl.s ——互联型的器件
包括：STM32F105xx，STM32F107xx
startup_stm32f10x_hd.s ——大容量器件
包括：STM32F101xx，STM32F102xx，STM32F103xx
startup_stm32f10x_hd_vl.s ——大容量器件
包括：STM32F100xx
startup_stm32f10x_ld.s ——小容量器件
包括：STM32F101xx，STM32F102xx，STM32F103xx
startup_stm32f10x_ld_vl.s ——小容量器件
包括：STM32F100xx
startup_stm32f10x_md.s ——中容量器件
包括：STM32F101xx，STM32F102xx，STM32F103xx
startup_stm32f10x_md_vl.s ——中容量器件
- startup_stm32f10x_ld_vl.s: for STM32 Low density Value line devices
- startup_stm32f10x_ld.s: for STM32 Low density devices
- startup_stm32f10x_md_vl.s: for STM32 Medium density Value line devices
- startup_stm32f10x_md.s: for STM32 Medium density devices
- startup_stm32f10x_hd.s: for STM32 High density devices
- startup_stm32f10x_xl.s: for STM32 XL density devices
- startup_stm32f10x_cl.s: for STM32 Connectivity line devices
cl：互联型产品，stm32f105/107系列
vl：超值型产品，stm32f100系列
xl：超高密度产品，stm32f101/103系列
ld：低密度产品，FLASH小于64K
md：中等密度产品，FLASH=64 or 128
hd：高密度产品，FLASH大于128
2、修改Device 为 STM32F103C8T6
3、更换全局宏定义
在C/C++选项卡内 修改为STM32F10X_MD,USE_STDPERIPH_DRIVER
二、移植uCOS III内核到C8T6过程中会遇到

需要修改
//lib_cfg.h
#define LIB_MEM_CFG_HEAP_SIZE 27u * 1024u /* Configure heap memory size [see Note #2a]. */
这里把堆空间设置为27K。。。。堆空间都比RAM还大了，这程序怎么可能在单片机是正常运行，把堆空格改为10K，程序编译通过。
#define LIB_MEM_CFG_HEAP_SIZE 10u * 1024u
