我目前正在开发对天空微尘的无线编程支持。附件是我目前拥有的文件。我基本上是在尝试使用 sky-shell-exec 示例将修改后的 test-deluge.ce 文件加载到 mote 上。然后我尝试使用 shell 'exec' 命令运行 test-deluge 文件,就像在 sky-shell-exec 示例中所做的那样。
最终目标是将 test-deluge.ce 和 hello-world.ce 编译的文件加载到 mote 上,然后能够“执行”我的 test-deluge.ce 文件,然后找到存储的 hello-world.ce文件并对其执行 deluge_disseminate 。
我正在运行的命令进度如下:
1) sudo make TARGET=sky clean CLEAN=symbols.?
2) sudo make sky-shell-exec.sky TARGET=sky
3) sudo make sky-shell-exec.sky CORE=sky-shell-exec.sky TARGET=sky
4) sudo make sky-shell-exec.upload CORE=sky-shell-exec.sky
5) sudo make compile-test-deluge-executable
6) sudo make upload-test-deluge-executable
7) sudo make login
8) ls (to see that the file made it)
9) exec test-deluge.ce
此时我收到“找不到符号:deluge_disseminate”错误
我相信错误出现在 make 的“CORE=...”部分(在上面的步骤 2 中)。我检查了上面第 2 步中填写的 symbols.c 文件,确实没有 deluge_disseminate 的符号或我记得的任何 deluge 命令。
对于实验,我尝试了以下方法:
sudo make test-deluge.sky TARGET=sky
sudo make test-deluge.sky CORE=test-deluge.sky TARGET=sky
我发现 deluge 的符号在那里,但我无法继续正确制作 sky-shell-exec 文件,因为这样做会擦除符号表并写入一个新表。
我觉得必须有一个简单的解决方法,因为我可以按照上述步骤(1-9)从 sky-shell-exec 示例目录运行 hello-world。
有谁知道如何解决这个问题?
注意:我的 test-deluge.c 中可能存在一个错误,我尝试打开“hello-world.sky”而不是“hello-world.ce”...我不太确定是哪一个。由于上面解释的缺少符号问题,我还无法对此进行测试,但如果有人愿意阐明这个问题,我将非常感激。
谢谢
