你刷的是8G的H3版对吗?
你用文本形式打开,P518ZCDH3.cfg文件,
会出现
[BinaryFiles]: P518ZCDH3_1.bin, 0x1000000
[BinaryFiles]: P518ZCDH3_2.bin, 0x2000000, IGNORE_SIGNATURE
[Ram CS]: 7, RamCS7_805.s37, LOCAL
[Flash CSs]: AUTO_DETECT, 5, 6
[Download Mode]: NORMAL
[Terminate Mode]: TERMINATED
[Comm Mode]: WIRED_MODE
[Baud Rate]: 460800
[Processor type]
805
[Customer Flash Select]: DISABLE
把460800变成115200,就OK了!
