Compiled the SDK but missing modules.dep

Posted: 2026-06-10 5:29

I'm trying to compile Lyra SDK (Luckfox_Lyra_SDK_250815) for Lyra Plus SPI NAND buildroot target.

The build process finished, but I there's no "modules.dep" in "/usr/lib/modules/<kernel_version>" directory.

Code: Select all

dev@ubuntu2204:/luckfox$ ls -1 output/buildroot/target/usr/lib/modules/6.1.99/
kernel
modules.builtin
modules.builtin.modinfo
modules.order

I've successfully flashed it to the Lyra Plus device, but ethernet and usb (adb) didn't work, since the modules couldn't be loaded because of missing "modules.dep".

Did I miss something? Thanks.

Please attach the logs from running ./build.sh kernel (no need to clean and rebuild), or the logs with the "post-rootfs" prefix located under $SDK/output/sessions/. The kernel modules are copied to the target when building the rootfs. Providing the logs will facilitate further analysis.

Warning: 'make modules_install' requires depmod. Please install it.
This is probably in the kmod package.

Ah solved, I need to install "kmod" package.

(It doesn't mentioned in the wiki. I guess it's pre-installed in default Ubuntu. But, since I didn't use normal Ubuntu, I need to install it.)

Thanks.
