The command for installing the kernel modules didn't work correctly for |
| 2 |
me. When I typed |
| 3 |
ROOT=/embedded_rootfs make modules_install |
| 4 |
the modules where installed in my development host's /lib/modules. |
| 5 |
|
| 6 |
I could instruct the Makefile to install the modules in embedded_rootfs |
| 7 |
using: |
| 8 |
make INSTALL_MOD_PATH=/embedded_rootfs modules_install |
