Building modules directly on the Beagleboard-xM Rev C

Vladimir Gajinov
Intellectual 350 points

Hello everyone,

I'm using Beagleboard-xM Rev C, Linux kernel 2.6.38.8, Angstrom distibution. "u-boot" loads kernel from NFS and kernel mounts NFS root. My network configuration is OK and I can boot Linux kernel. For network setup I followed this link: http://veter-project.blogspot.com/2012/03/comfortable-kernel-workflow-on.html

Now, I want to insert HID module into my kernel but I have few problems:

  1. I added "HID Gadget" as a module in menuconfig (Device drivers ---> USB Support ---> USB Gadget Support ---> [M] HID Gadget). I built my kernel and modules on the host computer (Linux Ubuntu 12.10) with this instruction: cross make -j5 uImage modules. Everythig passed without errors and I got g_hid.ko in "/linux/drivers/usb/gadget/" folder. After that I installed modules in "/lib/modules/2.6.38.8/" with: sudo_cross make -j5 modules_install. There is g_hid.ko in "/lib/modules/2.6.38.8/kernel/drivers/usb/gadget/" folder but when I tried to insert module I got an error. insmod returns me an error something like: insmod: error inserting 'g_hid.ko': -1 No such device. I can't figured out why... lsmod returns me an empty list, but that's expected because lsmod returns a list of loaded modules.
  2. When I built modules directly on the Beagleboard-xM Rev C with GCC compiler downloaded from "www.angstrom-distribution.org" with "opkg install xxxxxx" feature, I got from lsmod only one module in the list "twl4030_pwrbutton". Of course, I built modules on the board with make ARCH=arm modules and then make ARCH=arm modules_install. Still I have g_hid.ko in "/lib/modules/2.6.38.8/kernel/drivers/usb/gadget/" folder but I can't get my g_hid.ko module in lsmod. 


I need quick answer... Please help me.

Any suggestion would be appriciated...



Best regards,

Vladimir

    The insmod error message is most likely because you did not use the newly built uImage, and probably the current one already has a gadget driver built in, so you cannot insmod a second gadget driver.

    Please do a quick check if you use the new uImage which comes from the build with g_hid.ko.

    Hi Bin Liu,


    Thanks for quick peply... I cheked my menuconfig again and I found that "HID Devices" is "built-in" (Device drivers ---> [*] HID Devices ---> -*- Generic HID support AND <*> USB Human Interface Device (full HID) support). That means uImage has already a gadget driver built in? If I uncheck "[ ] HID Devices", can I insert module then?


    Firstly, I built uImage and modules together with cross make -j5 uImage modules and then I built modules on my Beagleboard-xM with make ARCH=arm modules. Is this wrong?


    Regards,

    Vladimir

    Yes, that means HID gadget driver is already built in, you don't need to insmod anything, just boot up xM board, and connect to host, the host should enumerate it as a HID.

    Vladimir Gajinov said:

    I never tried that. If uncheck, then it does not build hid.ko, how to get one to insmod? To get the module, you have make the option to '[M]'.

    You already got the module and uImage in the first step. why build the module again on xM? I never did that.

    Sorry, my response is wrong, the option you did above is HID host support, it is irrelevant to HID gadget.

    Bin Liu,

    I did some stupid things because I don't know what else to do :) I tried everything but nothing helps... I'm pretty desperate :) Do you have any other idea?

    Thanks for help!

    I don't know much about the 2.6.38.8 kernel, I guess it is not provided by TI.

    But it seems to be working for you, but only except the USB gadget. So You can do a quick check:

    When you did make uImage modules, you got uImage and g_hid.ko (assuming you enabled HID gadget as module, the message above shows you did), so update the new uImage to you filesystem and g_hid.ko. Then boot the board and insmod g_hid.ko, to see if it works.

    The rule here is always use the uImage and modules, which come from the same build, at the same time.

    I built uImage and modules together, installed modules and then reboot BB-xM but it is the same behaviour. Still, I can't insert module. With modinfo g_hid i got:

    filename: /lib/modules/2.6.38.8/kernel/drivers/usb/gadget/g_hid.ko
    license: GPL
    author: Fabien Chouteau, Peter Korsgaard

    srcversion: DF28552EA5AAC8D1F62467D
    depends:

    Can there be a problem with compiler i.e. maybe I'm using wrong GCC?! Maybe modules are built for some other platform so the BB-xM doesn't recognize them? I don't know, maybe that's stupid thinking... I downloaded GCC from http://www.angstrom-distribution.org/feeds/unstable/ipk/glibc/armv7a/base/gcc_4.3.3-r24.1.6_armv7a.ipk

    Did you put the new uImage into your filesystem?

    Please paste the output of 'uname -a'.

    Or please attach the file '/proc/config.gz' here if you have it enabled.

    Here is the output of uname -a:

    The .config does not have CONFIG_USB_GADGET_MUSB_HDRC=y.

    Please do menuconfig and

    Device Drivers ->
        [*] USB support  --->
            Driver Mode (USB Peripheral (gadget stack))  ---> (select 'USB peripheral' or 'Both host and peripheral:  USB OTG (On The Go) Device')

    I selected "Both host and peripheral:  USB OTG (On The Go) Device" because I will connect BB-xM with mobile phone over OTG cable but I can't build kernel now. Here are the errors:

    drivers/tty/serial/omap-serial.c: In function 'serial_omap_irq':
    drivers/tty/serial/omap-serial.c:151:16: warning: 'ch' may be used uninitialized in this function
    drivers/tty/serial/omap-serial.c:151:16: warning: 'ch' may be used uninitialized in this function

    make[2]: *** [drivers/usb/musb/musb_core.o] Error 1
    make[1]: *** [drivers/usb/musb] Error 2


    The error said: select CONFIG_USB_GADGET_MUSB_HDRC. Then I must select Inventra HDRC USB Peripheral (TI, ADI, ...) in Device drivers ---> USB Support ---> USB gadget support ---> USB Peripheral controller ---> select "Inventra HDRC USB Peripheral (TI, ADI, ...)" instead of "OMAP USB Device Controller". Now, I'm able to compile kernel but the behaviour is same. I rebooted my BB-xM and then tried to insert module but I got the same error. Somewhere I read that I need to run depmod before insmod. Is that true?

    That is correct. Beagle xM uses DM37xx which does not have 'OMAP USB Device Controller'.

    Please provide the new /proc/config.gz

    Instead tt is better to do 'make modules_install' once, since this is not a trivial kernel config change.

    I'm not sure that I understand what you want to say with "Instead tt is better to do 'make modules_install' once, since this is not a trivial kernel config change.". After every modules compilation I did make ARCH=arm modules_install. That's correct?

    config.gz
  • 0 in reply to Vladimir Gajinov
    TI__Guru**** 167581 points

    That is correct. (sorry, I did not know you did modules_install to populate the modules) modules_install will do 'depmod' for you.

    I am not sure if that is the root cause, but the config.gz still has a couple CONFIG missing which are related to USB/MUSB. Is it possible you can try the attached config? it is for 2.6.37 kernel provided by TI.

    You can also download the 2.6.37 kernel for AM37xx/BeaglexM from am37x-evm-sdk-src-05.07.00.00.tar.gz

    Or 3.3 kernel for XM: beagleboard-sdk-src-05.07.00.00.tar.gz

    Bin,

    I tried config file which you provided (1263.omap3_beagle_defconfig.txt) but it doesn't work.

    Is this SDK beagleboard-sdk-src-05.07.00.00.tar.gz especially for Beagle board - xM Rev C? .config file is written for BB-xM?

    I personally did not test it on BB-xM, but yes, this package is dedicated for Beagleboard, including xM.

    Bin,

    I can't boot that version of kernel via NFS. I extracted Linux kernel 3.3.7 into /rootfs/usr/src/ folder, built it with cross make -j5 uImage modules command from this blog: http://veter-project.blogspot.com/2012/03/comfortable-kernel-workflow-on.html. Now, I can load uImage but it stops:

    One guy, RobertCNelson, told me "Yuck...v3.3.x was a crap shoot with respect to usb....." and he suggested me to patch the kernel (3.3.7) with this patches: https://github.com/RobertCNelson/stable-kernel/tree/v3.3.x/patches/beagle

    0001-ARM-OMAP3-USB-Fix-the-EHCI-ULPI-PHY-reset-issue.patch

    0001-omap3_beagle-init-uart2-for-beagle-rev-AX-BX-only.patch


    I patched Linux kernel 3.3.7, built it and tried to boot but still I can't get login prompt. Do you know something about that problem in Linux kernel 3.3.7?

    I personally don't have experience on 3.3.x kernel and don't have comments for the patches you listed.

    The error message you had before 'error inserting 'g_hid.ko': -1 No such device.' is due to incomplete hid gadget driver. You can follow Documentation/usb/gadget_hid.txt to add your own platform device portion.

    For your reference, the following patch is what I tried and it works with the 3.3 kernel from the link I provided above with SD card boot.

    Bin,

    Now, I can insert g_hid.ko module but I can't get hidg file in /dev/ folder. I can't figure out why?!

    Vladimir

    I have /dev/hidg0 on my BBxM.

    Do you use the root filesystem provided in the TI SDK package?

    Please provide the kernel log when 'insmod g_hid.ko'.

    Bin,

    No, I don't use root filesystem provided in the TI SDK package. I used root filesystem (Angstrom-Beagleboard-demo-image-glibc-ipk-2011.1-beagleboard.rootfs.tar.bz2) from this site: http://downloads.angstrom-distribution.org/demo/beagleboard/

    Never mind, now I'm starting to develop on SBC8018 board. I hope I'll have less problems than with BeagleBoard-xM.



    Thank you anyway for help,

    Vladimir
