Description

The frame buffer device (/dev/fb0) is not available when WRLinux is booted without connecting a VGA cable. "No such Device" error occurs when invoking fbset command.

Steps to Reproduce

1. Create a Linux Platform Project with the following settings.
board: intel_core_qm67_pch
kernel: standard
rootfs: glibc_std

2. Build Kernel/RFS.
3. Boot the Linux without connection a VGA cable.
4. Check the frame buffer device with invoking fbset command as the following log.

  # fbset -i
  open /dev/fb0: No such device

5. Result of invoking fbset is the following log, if the Linux is booted with connecting a VGA cable.

# fbset -i
mode "1280x1024"
    geometry 1280 1024 1280 1024 32
    timings 0 0 0 0 0 0 0
    rgba 8/16,8/8,8/0,0/0
endmode

Frame buffer device information:
    Name        : inteldrmfb
    Address     : 0xd2030000
    Size        : 5242880
    Type        : PACKED PIXELS
    Visual      : TRUECOLOR
    XPanStep    : 1
    YPanStep    : 1
    YWrapStep   : 0
    LineLength  : 5120
    MMIO Address: 0xf8400000
    MMIO Size   : 4194304
    Accelerator : No

6. Connect a VGA cable after step4 is done. But, result of invoking fbset is no same as step5, and it is the same as step4.
