基本硬件：树莓派4B，安装ubuntu 24.04服务器版本，使用daed的armv7版本,我在使用daed项目时，提示nanotime returning zero about daed

Thanks for opening this issue!

nanotime returning zero.that's all.

树莓派4B是arm64的，你下载armv7的daed使用可能会有问题，

uname -a

似乎是没有CONFIG_DEBUG_INFO_BTF=y 这一项吗？ 我看到官方要求的内核是需要开启这一项，如果是树莓派需要如何开启它呢？

我更换了arm64版本依然无法运行。

[mzz2017]

1. 你的操作系统要选 arm64(aarch64)
2. 你需要重新编译内核以加入 btf 支持
3. “依然无法运行”没有任何日志反馈
