STM32F103C8T6移植FreeRTOS后编译失败

使用STM32F103C8T6移植FreeRTOS的时候，编译会失败，但是在Stm32F103VET6工程上编译没问题，编译之后报以下错误

这个是由于stm32f103c8t6的内存不足导致的，c8t6只有64k（实际上有128k，配置为128k一般也不会出问题），而vet6有512k，因此直接用vet6上 的FreeRTOS移植过来会导致内存不足的情况。
解决办法：
修改FreeRTOSConfig.h内的

#define configTOTAL_HEAP_SIZE					((size_t)(20*1024))

为

#define configTOTAL_HEAP_SIZE					((size_t)(10*1024))

也就是修改FreeRTOS系统所有总的堆大小，之后编译便会通过。
在网上还看到过修改程序优化等级的，不建议大家使用，首先把程序优化等级调节到最大。也就是Level 3(-O3)，那么程序出奇葩问题的可能性也就最大，其次这样真正来说也节约不了多大内存，大家如果想在日后少死掉点脑细胞，建议还是设置优化等级为Level 0(-O0)！
