预期/说明：

该st-flash将成功将zeptoforth.bin写入STM32L476 MCU的闪存中，地址为0x08000000。

注意：如果没有提供足够的信息，则可能会关闭此错误报告，恕不另行通知！

谢谢您的支持。

我在Nucleo STM32L476RG开发板及其板载ST-LINK / V2-1的开发分支中测试了该补丁。 该补丁修复了回归问题。 感谢您查看这个。

我在Nucleo L476RG板上遇到了同样的问题，无论是stlink 1.5.0还是1.6.0都能为我工作，但是git的最新版本会产生以下输出（在我停止将USB日志消息发送到stdout的垃圾邮件之后）：

我认为这可能是时间问题。 我在stm32l432上遇到了同样的问题。 我在flash_loader.c中进行了以下更改，似乎可以解决该问题。 我毫不犹豫地说这是根本原因。

@geoffreymbrown ： @tabemann和/或@Crest验证后，您可以作为PR提交吗？
