通过Ymodem OTA失败

大家好：
	我根据[STM32通用bootloader升级](https://www.rt-thread.org/document/site/#/rt-thread-version/rt-thread-standard/application-note/system/rtboot/an0028-rtboot)文档进行操作，一切都很顺利，固件可以通过`bootloader`正常跳转到`V1.0.0`的固件运行。
但是我通过`TeraTerm`软件给`MCU`发送固件后，就不能正常跳转到`V2.0.0`执行了。

以下是生成`bootloader`的配置：

以下是升级过程中，`MCU`串口的日志：

以下是`V2.0.0`固件打包的设置：

我已经尝试好多次了，但还是不行，不知道问题在哪里，请大佬们指教，谢谢！

还有就是想问一下：`固件打包器`里面的`固件分区名`和`固件版本`是随便设置吗，还是说需要怎么确定啊？
