1，芯片：gd32f303rct62，boot0和boot1都接地。
3，同样的程序stm32f103rct6没有问题。
4，实验内容：通过dma+pwm，控制pb3，输出波形，从而控制rgb灯的点亮，熄灭和颜色。但是程序烧录后，只有在debug模式下程序才能正常运行（点击魔术棒，然后点debug，再点setting不做任何设置，直接退出，程序能自动正确运行）。如果拔除jlink与开发板连线，直接重启电源或按复位都不能正确运行程序。请哪位大佬能不能帮忙看看，我写的配置程序有没有问题，帮忙分析一下原因。
5，void vLED_init(void)，为驱动配置程序。
6，void vSetLED(uint8_t (*color)[3],uint16_t len)，为通过dma+pwm向rgb灯芯片发送数据
问题已经解决了，配置gpio remap时不仔细一个参数配置错了，正确的是（GPIO_SWJ_SWDPENABLE_REMAP）。
