Problably the issue about modules.builtin was a nosense, becasuse patching the kernel Makefile in order to include this file dosen't fix the problem.
That said, I am unable to make work properly the /lib/modules folder. The problem is the "make modules_install" is not putting all the files in the target folder (I mean the modules.dep files an so on). This is the log output when the task do_install of the kernel.bbclass: [...] DEPMOD 2.6.32-abacus + bbnote 'JAVI -> ls INSTALL_MOD_PATH' + echo 'NOTE: JAVI -> ls INSTALL_MOD_PATH' NOTE: JAVI -> ls INSTALL_MOD_PATH + ls -l /home/jroman/poky.git/build/tmp/work/romley-poky-linux/linux-yocto-abacus/2.6.32+gitAUTOINC+459b3d520991ec1b8e5ba68fbc4b206d602fee6e-r1/image/lib/modules/2.6.32-abacus/ total 40 lrwxrwxrwx 1 root root 163 Jun 14 10:08 build -> /home/jroman/poky.git/build/tmp/work/romley-poky-linux/linux-yocto-abacus/2.6.32+gitAUTOINC+459b3d520991ec1b8e5ba68fbc4b206d602fee6e-r1/linux-romley-standard-build drwxr-xr-x 9 root root 4096 Jun 14 10:08 kernel -rw-r--r-- 1 root root 6380 Jun 14 10:08 modules.builtin -rw-r--r-- 1 root root 16509 Jun 14 10:08 modules.order lrwxrwxrwx 1 root root 141 Jun 14 10:08 source -> /home/jroman/poky.git/build/tmp/work/romley-poky-linux/linux-yocto-abacus/2.6.32+gitAUTOINC+459b3d520991ec1b8e5ba68fbc4b206d602fee6e-r1/linux [...] The make modules_install uses the target folder INSTALL_MOD_PATH in order to install the modules, however you can see only the files "modules.builtin" and "modules.order" are properly installed. The "make modules_install" work fine if I run this command from a "devshell", however from the "bitbake virtual/kernel -c install" is not properly working. Can anybody give me a hint? Many thanks.
