Debugging 错误：ELF文件无效，仅支持32位文件

我正在尝试调试HiFive上的hello world应用程序，该应用程序是使用PlatformIO Core（CLI）工具发布的。我已使用以下Wiki设置了该实用程序：

并使用以下命令调试应用程序：

启动调试会话时，我遇到一个奇怪的错误：

Error: invalid ELF file, only 32bits files are supported
embedded:startup.tcl:486: Error: ** Programming Failed **

以下是完整的详细日志：

任何消除此错误的指针都将非常有用

谢谢。

什么是“readelf-h.pio/build/sifive hifive unreleased/firmware.elf”的输出？更新了我问题中的输出。默认情况下，我得到了一个32位elf文件。因为它是为rv32imc arch编译的。您可以添加“platformio run-v”的输出来查看编译命令吗？你修改过拱门了吗？我得到了64位ELF文件，并设置为rv64imac。添加了一个有问题的日志片段。好的，是@yflion，是openocd不支持rv64。我在这里打开了platformIO的一个问题：
