Hi every body! I am working on a set top box reference design based on the chip st7109 and I use STLinux 2.2. I want to insert the framebuffer module (named stmfb_stb7100). For this I did like the official web site of STLinux indicates for me ( http://www.stlinux.com/docs/release-note-2.0ear/framebuffer.php). First I activates the kernel framebuffer options, rebuild it and then I built the framebuffer module and install them. All the necessary modules are inserted perfectly (cfbcopyarea.ko , cfbfillrect.ko, cfbimgblt.ko) but an error occurs during inserting the framebuffer module (stmfb_stb7100) : # insmod stmfb-stb7100.ko insmod: error inserting 'stmfb-stb7100.ko': -1 No such device same thing using modprobe : # modprobe stmfb-stb7100.ko FATAL: Module stmfb_stb7100.ko not found. any suggestion to overcome this problem? |

Hi, If you post your doubt on ST Bugzilla database on https://bugzilla.stlinux.com/ you can get better support and search for similar problems. BTW, this error comes because you don't have /dev/fbv device. I never used 2.0 version of STLinux, but if version 2.2 I need to insert another module called stmcore-display-stxXXXX.ko. I suggest you update do a newer version and try these new modules. ftp://ftp.stlinux.com/pub/stlinux/2.3/updates/RPMS/host/stlinux23-host-stmfb-source-3.0_stm23_0018-33.noarch.rpm Best regards, Tiago Maluta |

I boot STLinux kernell using NFS.

Yes! All device entries are treated as a file in Linux. Send me your .config file.
