请问如何能够鉴定DM6467是否故障
不知道你的具体需求是什么?谢谢说明
我有一块好的DM6467，我有一次用示波器测试了晶振后，发现DM6467再也启动不了了，CCS也连不上6467，我更换了晶振，但是问题依旧存在。请问这是DM6467烧了吗？
先确认电源部分是否有问题.上电时序是否正确
我测试过了，电源部分没问题
You have mentioned your replaced the OSC/CRYSTAL, so have you measured the clocks has been generated ?
我检查过，时钟没有起振
我检查过，晶振没有起振
请问各位这是DM6467坏了吗
