Subject: [PATCH] [bsp][APM32][APM32F407VGT6] (#6377)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

使用APM32F407VGT6芯片发现shell命令行无法接收命令，解决shell命令行输入问题

将board.c中的：
GPIO_ConfigStruct.mode = GPIO_MODE_IN;
GPIO_ConfigStruct.pupd = GPIO_PUPD_UP;
修改为：
GPIO_ConfigStruct.mode = GPIO_MODE_AF;
GPIO_ConfigStruct.pupd = GPIO_PUPD_NOPULL;

使用APM32F407VGT6测试成功
