How to enable option module

[Harun]

Hello,

I have an iMX233-OLinuXino-MAXI with Arch Linux and I need to enable "option module". When I run the "modprobe option" command, I get an error message saying "FATAL: Module option not found.".

Can you please let me know how to enable this module?

Thanks, Harun

Hi,

If you want to be able to load kernel modules you need a kernel with "loadable module support", it is likely that you are using a kernel where this was not enabled. So you have to rebuild your kernel with "loadable module support":

Code Select Expand


Loadable module support  --->
  [*] Enable loadable module support
  [*]   Module unloading
  [ ]   Module versioning support (EXPERIMENTAL)
  [*]   Automatic kernel module loading


I've tested it on my laptop:

Code Select Expand


[chris@thinkpad ~]$ sudo modprobe option
[chris@thinkpad ~]$ lsmod |grep option
option                 34230  0
usb_wwan               19189  1 option
[chris@thinkpad ~]$ locate option.ko
/usr/lib/modules/3.6.10-2.fc17.x86_64/kernel/drivers/usb/serial/option.ko
/usr/lib/modules/3.6.8-2.fc17.x86_64/kernel/drivers/usb/serial/option.ko
/usr/lib/modules/3.6.9-2.fc17.x86_64/kernel/drivers/usb/serial/option.ko


You probably also need to enable:

Code Select Expand


Device Drivers  --->
  [*] USB support  --->
    <*>   USB Modem (CDC ACM) support
    <*>   USB Serial Converter support  --->
      [*]   USB Generic Serial Driver
      <*>   USB driver for GSM and CDMA modems
  [*] Network device support  --->
    <*>   PPP (point-to-point protocol) support
    <*>     PPP support for async serial ports


What do you want to do, maybe there is another way to achieve this, where do you have read that you should run "modprobe option".

I think it is the better to rebuild the kernel with the needed modules built-in and not as a module e.g. you select [ * ] instead of [M] when configuring your kernel.

Hi,
I work on connecting my Olinuxino-Maxi to internet using a 3G dongle but it is a Huawei HiLink modem, it acts as an ethernet interface, not usb. It requires option module enabled.

This is also a USB 3G modem I'm sure you can skip the modeprobe step when build the drivers not as modules, e.g. select:

Code Select Expand


Device Drivers  --->
  [*] USB support  --->
    <*>   USB Modem (CDC ACM) support
    <*>   USB Serial Converter support  --->
      [*]   USB Generic Serial Driver
      <*>   USB driver for GSM and CDMA modems
  [*] Network device support  --->
    <*>   PPP (point-to-point protocol) support
    <*>     PPP support for async serial ports


when configuring your kernel.

Than you use wvdial to set up your network connection.

If you do not post all commands that are necessary to configure your modem or a link to the guide where you have read them than I can't help you how to do it on the olinuxino. Also the output of every command is very helpful.

What does happen when you insert your 3G modem, do you see something like this:
