STC8H3K64S2不能使用，说是波特率设置读取不匹配，在win下用STC官方烧写程序正常。

就是希曼 创建了任务

运行的这个版本不是最新的

在检测到型号"detected MCU type: STC8H3K64S2" 之前已经出错了, 一直停留在状态5, 正常情况这时候应该到状态9, 然后在切换波特率后再来一遍状态1到状态9.

试试直接clone仓库的代码编译一个, 1.2之后改动挺大的. 如果不方便编译的话我这周会放一个1.3上来, 到时候再试试.

重新clone了一下仓库，1.2版的，重新编译还是一样的问题。等待着你的1.3版。 :v:

之前用STC8H3K32S2比较多, 担心和STC8H3K64S2有型号差异, 今天贴了一片试试, 好像没发现问题

型号和固件版本都是一样的, 也许是USB2TTL有差异? 我用的是CH340G和CP2102

Debug信息如下

用了一下1.3,还是一样的问题，出错的位置还是一样。

我用的是CH340N,用的是自动下载电路（CH340N的RST管脚控制一个PMOS开关电源），在win下刷写程序没有问题。同样的电路用在了STC15上用你的下载器也是没有问题的。我也觉得很奇怪，下次我试试把自动下载电路换成手动的吧。

应该和自动下载关系不大, 我现在也用的自动下载. 看来我得跑个manjaro看看, 莫非这两发行版里的ch340驱动有变化.

另外，我看了另一个issus里面的兄弟也是和我一样的问题，我们使用的都是manjaro,你的好像是ubuntu吧？是不是这个造成的问题？

上面这个问题把波特率提高为1152000后，情况有所好转。你的程序很好，辛苦了！

可能还是有某些配置的差异, 我测的每次读取只有几个字节, 但是出状况的输出, 都是每次读取几十个字节, 也许和STC-ISP设置的IRC频率有关? 我一般都设成24MHz, 下次我写成11.0592MHz看看.

@就是希曼 我今天用新打的板子新做了一个自动下载, 结果正好复现了这个问题. 已经把修复提交上去了, 可以本地编译一个试试看是否能解决问题.

这个问题貌似和uart通信的机制有关, 但是我不确定这种区别是CH340引起的还是MCU引起的

如果每次读取是一两个字节的情况, 通信间隔很短没问题, 如果是每次读取二三十个字节的情况, 中间通信间隔时间会超过100ms, 正好就超过了程序里设置的超时时间, 现在把超时时间增加到320ms就没问题了.

1.4版已经在manjaro和win11下编译通过并且可以正常烧录程序了，分别用24M和11.0592M都测试了没问题。

目前还有一个问题，每次烧录都要加-e参数，不然不能烧写成功，是不是直接就把这个参数作为默认参数编译进程序中？
