是不是FLASH被鎖了啊?能不能不用USB解鎖.板子沒有USB口

您好，麻煩你截一張完整的指令和信息輸出圖，這邊看一下，可將截圖發(fā)至我的郵箱（lzs@wch.cn）?；蛘吣銍L試將BOOT0接VCC重新上電下載看一下，看能否下載燒錄。

這是我用OpenOCD+Telnet操作的情況:

program指令運(yùn)行時(shí)直接奔潰了

使用flash write_image指令一樣的結(jié)果

在MRS里面用菜單里的燒錄

您好，建議你先用WCHISPTool工具通過串口方式解除讀保護(hù)，重新下載程序試一下，注意不要勾選啟用讀保護(hù)。使用串口方式下載時(shí)：BOOT0接VCC，BOOT1接GND，使用的串口工具要注意防倒灌電。串口接串口1（PA9、PA10引腳）。后面若有問題，可將問題發(fā)我郵箱（lzs@wch.cn）.
