一、问题
使用 GD32F10x_Firmware_Library_V2.2.2 固件库样例工程 Template 修改设备型号为 GD32F103RC
编译报以下错误:
*** Using Compiler 'V5.06 update 4 (build 422)', folder: 'D:\\Keil_v\\ARM\\ARMCC\\Bin'

二、原因
GD32选型表 中找到 GD32F103RCT6
中密度产品(GD32F10X_MD) 是指 FLASH 存储器容量在
16 KB 至 128 KB
的 GD32F101xx 和 GD32F103xx 微控制器。
高密度产品(GD32F10X_HD) 是指 FLASH 存储器容量在256KB 至 512KB
的 GD32F101xx 和 GD32F103xx 微控制器。
超高密度产品(GD32F10X_XD) 是指FLASH存储器容量在512KB 以上
的GD32F101xx 和 GD32F103xx 微控制器。
互联型产品(GD32F10X_CL) 是指产品是指 GD32F105xx 和 GD32F107xx 微控制器。
所以 GD32F103RCT6 处于 HD 的产品,器件选型如果选错,就会冲突。startup_gd32f10x_hd.s 。 在KEIL5的器件选型里,注意选的器件全名跟你的启动文件是吻合的!
三、解决方法
点击 Options of Target 在 C/C++ 选项里面将 Define GD32F10X_CL
改为 GD32F10X_HD
。
