GD32E230这个系列MDK仿真还缺什么东西吗？是不是不支持M23内核

TIMER0用于电机驱动的3路PWM互补模式

GD32E230的片子做低功耗的时候，进入低功耗重新配置外设后ADCDMA采集通道数据直接错乱了乱了。比如原来肯能dmA通道一置换的数据是电池电压数据，2通道是传感器电压值。但是低功耗唤醒后重新配了一遍外设，采集数据可能就错乱了。请问论坛的大佬有遇到这个问题嘛？该如何解决？

GD32E230 AD采样，单片机每次复位重启后AD采样值都不一样，请问有人知道是什么原因吗？

我使用GD32E230C8T6，遇到的问题是这样的：1，调试时，程序没执行，点停止后，汇编的第一句是0x20000000:B 0x20000000，应该是一直在原地跳转。2，调试时，只要不断电，芯片能识别到，只要一断电，芯片再也识别不到了。

#ifdef USE_IWDG_ENABLE IWDG_Process(); #endif 在这样的函数中 IWDG_Process()选中 按F12无法跳转，提示NO information available for the selected symbol [b][color=#000][font=Tahoma, Arial, Helvetica, snas-serif][size=14px] 路径全英文。IWDG_Process 单独拿出来反而能跳转。[/size][/font][/color][/b]#define XXX (gpio_bit_set(XXX,XXX)) 选中gpio_bit_set按F12无法跳转到gd32e10x_gpio.c文件，单独拿出按F12能跳转 什么情况

如题，STM32F0移植到GD32E230,FLASH写入数据时导致ADC采出来的数据产生混乱，只要不向FLASH写入数据，ADC采出来的数据就没有问题，关于flash的操作已经使用32位操作

GD32E230C8T6在波特率115200烧录会出错，需要降频烧录才能成功，这是什么问题？

我想请问下，有没有人用eclipse搭建成功过GD32E230的编译环境？

串口发送初始化为(PA9)中断发送方式，初始化代码如下：/* enable COM GPIO clock */ rcu_periph_clock_enable(RCU_GPIOA); /* enable USART clock */ rcu_periph_clock_enable(RCU_USART0); /* configure USART Tx as alternate function push-pull */ gpio_mode_set(GPIOA, GPIO_MODE_AF, GPIO_PUPD_PULLUP, GPIO_PIN_9); gpio_output_options_set(GPIOA, GPIO_OTYPE_PP, GPIO_OSPEED_10MHZ, GPIO_PIN_9); /* connect port to USARTx_Tx */ gpio_af_set(GPIOA, GPIO_AF_1, GPIO_PIN_9); /* configure USART Rx as alternate function push-pull */ gpio_mode_set(GPIOA, GPIO_MODE_AF, GPIO_PUPD_PULLUP, GPIO_PIN_10); gpio_output_options_set(GPIOA, GPIO_OTYPE_PP, GPIO_OSPEED_10MHZ, GPIO_PIN_10); /* connect port to USARTx_Rx */ gpio_af_set(GPIOA, GPIO_AF_1, GPIO_PIN_10); /* USART configure */ usart_deinit(USART0); usart_baudrate_set(USART0, baud); usart_word_length_set(USART0, USART_WL_8BIT); usart_stop_bit_set(USART0, USART_STB_1BIT); usart_parity_config(USART0, USART_PM_NONE); usart_hardware_flow_rts_config(USART0, USART_RTS_DISABLE); usart_hardware_flow_cts_config(USART0, USART_CTS_DISABLE); usart_transmit_config(USART0, USART_TRANSMIT_ENABLE); nvic_irq_enable(USART0_IRQn, 0); usart_interrupt_enable(USART0, USART_INT_TC); usart_enable(USART0); 中断服务程序： void USART0_IRQHandler(void) { if(RESET != usart_interrupt_flag_get(USART0, USART_INT_FLAG_TC)) { usart_interrupt_flag_clear(USART0,USART_INT_FLAG_TC); UplinkDrv_Sending((uint_8*)&(USART_TDATA(USART0))); } } void UplinkDrv_Sending(uint_8 *reg) { if(UplinkFrame.Send.Pc >= UplinkFrame.Send.Len) { UplinkDrv_Recv_Creat(); } else { *reg = UplinkFrame.Send.Buff[UplinkFrame.Send.Pc]; UplinkFrame.Send.Pc++; } } 目前是不到发送完一个字节就多次进入该发送中断完成服务程序，导致发送失败。 大拿有遇到相关问题吗？

编译出来0错误0警告，MDK已经勾选Browse infomation，MDK和pack包安装路径是全英文，工程文件也是全英文，源文件全部放在src文件夹，头文件全部放在inc文件夹，文件夹直接放在工程目录下，目录深度只有一级，就差直接把所有源文件和头文件放在工程目录下了。但就是不支持跳转到定义，请问有人遇到过同样的问题吗？你们是怎么处理的？
