我正在学习DA14681开发工具包-基本与以下软件&
——SmartSnippets Studio v1.2.3.588
——DA1468x_SDK_BTLE_v_1.0.6.968

我试图遵循UM-B-056的第6节构建外设演示应用程序&QSPI闪存程序(使用program_qspi_serial_win)。第一次成功(复位后可以看到Tera Term的输出消息)。然而，它似乎不能被编程了，如果我想要编程其他演示代码或相同的外围演示应用程序。当它试图上载引导加载程序/应用程序可执行文件时，它总是报告下面的错误，你有什么想法吗?

"无法连接到设备。
Write executable failed: second stage bootloader rejected (-105)
