您好，我最近买的STM32F030C8T6芯片在刻录程�?�?��??�?�?�?，�?�能烧录一次。第一次烧录�?功�?�，通过外键�?�?�?�，芯片�?�?引脚会继续输出三角波，导致芯片无法正常�?�动，无法�?次烧录。您�?�能在移除外部晶体振�?�器�?��?新连接STM32 ST-LINK实用程�?刻录工具进行下载和刻录。连续七个芯片都是如此。你之�?买的薯片烧完�?�就正常了。�?然间，这个问题无法解决。检查电路�?�接线�?�?�?电路和晶体振�?�器电路是�?��?�正常。MCU 内部硬件�?�?使能控制�?选项字节设置无效。编写空程�?也有�?�样的问题。拆下外部晶体振�?�器�?�，使用STM32 ST-LINK实用工具擦除整个芯片，芯片的�?�?�?�?消失，但晶体振�?�器�?振动。
