BDT烧录出现flash不能unlock

维克喇叭

第一次烧录是ok，第二次烧录不行的
我使用BDT的版本是V5.8.0.6
首先板子和连接是成功的

点击

再点击

出现
错误现象：点击unlock


有试过多种点击方式，结果现象都是一样的（有试过 点击后，再点击 unlock，现象一致；主要原因是无法对flash解锁）

对此有何解决方案?

非常感谢你的回复，我的问题是点击unlock后，出错误了，EVK command result error；目前我的判断是代码运行起来了，unlock的命令下发不到板子上（或者说板子代码运行中，无法接收我unlock的指令），导致了错误产生。谢谢。

Thank you very much for your answer. Sorry, per company regulations, commercial products cannot be shown externally. Currently, my wiring should be okay because the first programming was successful. However, an issue occurred during the second programming attempt. I roughly suspect the cause is that the commands sent by the board's SWS pin cannot be properly received by the board (there is already a program on my board).
