How do I know what are the modules my beagleone has ?

Viveky1794 · October 1, 2023, 6:39pm

Hi all,

I recently build mainline kernel 6.6-rc3 . I also build modules as well. Steps are as below.


make ARCH=arm distclean
make ARCH=arm omap2plus_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage dtbs LOADADDR=0x80008000 -j10
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules -j10
sudo make ARCH=arm modules_install

Than transfer build kernel modules into SD card Rootfs partition.

sudo cp arch/arm/boot/uImage    /media/<user>/BOOT && sync
sudo cp -a /lib/modules/6.6.0-r23/     /media/<user>/Rootfs && sync

My beaglebone successfully booted. But Once I gave “lsmod” to check modules. I didn’t see any module.

Can someone pointout ? What is the issue with understanding ? I am not able to see usb or ethernet things if I execute “ifconfig” command.

I am not getting the issue. Please pointout.

Thanks & Regards
Vivek Yadav

have you tried, been a while since i’ve seen this issue.
sudo depmod -a

so… you copied your “host” modules to your microSD… in the base folder… ‘/’…

Looking above, you ran this command:

sudo make ARCH=arm modules_install

Just do this instead:

sudo make ARCH=arm modules_install INSTALL_MOD_PATH=/media/<user>/Rootfs/

Hi @RobertCNelson,

I tried below mention command

sudo make ARCH=arm modules_install INSTALL_MOD_PATH=/media/USER/Rootfs/

As you can see there are .ko files are there under /lib/modules/6.6.0-rc3/kernel/drivers/ folder.
Do I manually need to load all these drivers using insmod command.

Thanks & Regards

Now run what @amf99 recommended.

Viveky1794 · October 2, 2023, 4:20pm

I already tried this command depmod -a but it didn’t work for me.

You guys are most qualified person for this type of issue. I am beginner in embedded Linux.

RobertCNelson · October 2, 2023, 4:45pm

lsmod, should work after a reboot.

Viveky1794 · October 2, 2023, 4:50pm

Sorry to say but this method I tried, result is same. lsmod does not work after reboot also.

what image did you originally use? (provide a link if possible)

RobertCNelson · October 3, 2023, 7:31pm

@Viveky1794 built it from buildroot…

so a buildroot version and what config might be useful…

Regards,

Hi @RobertCNelson and @amf99.

so a buildroot version and what config might be useful…

utility- buidtroot GitHub - buildroot/buildroot: Buildroot, making embedded Linux easy. Note that this is not the official repository, but only a mirror. The official Git repository is at http://git.buildroot.net/buildroot/. Do not open issues or file pull requests here.
branch - master
defconfig- beaglebone_defconfig

Steps

sudo make beaglebone_defconfig
sudo make menuconfig

Kernel ==> kernel binary format(zImage)

sudo make -j20

If I use everything from buildroot. I can see lsmod listed all the available modules.
You can check log at last.
But I am facing issue if I compile mainline kernel and modules and transfer to BBB rootfs/lib/modules/.

Not good news,
Linux 6.6-rc3 does not boot, hangs at “Starting kernel” and reboots after about 30 seconds.
so I went back to Linux-6.5.5 stable, this crashes during boot
installing the modules and zImage should work, not sure why there not.

Hi @amf99,

Linux 6.6-rc3 does not boot, hangs at “Starting kernel” and reboots after about 30 seconds.

It also happen with me. Please check with working rootfs. In my case rootfs was the issue.

so I went back to Linux-6.5.5 stable, this crashes during boot
installing the modules and zImage should work, not sure why there not.
GL

Can you paste the steps and log of this experiment ?

Thanks & Regards
Vivek Yadav

I might have missed it, but I haven’t seen anyone recommend:

zcat /proc/config.gz

This should show a live list of config options used to build the running kernel.

here’s the story,
goal:
test if installing modules and zImage from Linux build outside of Buildroot works
Buildroot Linux version
v6.1.33-ti-r7
Linux version built outside of Buildroot
v6.1.26-ti-r5
On first boot after installing modules and zImage from V6.1.26, the BBB hung at “Starting Kernel”
it did not reboot like the other build/test that I did.
after about 30 seconds i press the reset button (just because )
the BBB booted to command prompt and uname indicated it was running V6.1.26
so it is possible to upgrade modules and zImage
Note:
I choose to use Linux version that were close to each other for this test.
the Linux versions came from github/beagleboard

this is the git info from the Linux version built outside of Buildroot;
git branch -v

amf99 · October 5, 2023, 7:41pm

since I’m setup,
Buildroot Linux version
5.10.162-ti-r59
Linux build outside of Buildroot
6.1.26-ti-r5
on first boot, BBB crashed
after pressing reset, BBB hangs at “Starting kernel”, does not reboot like prior test did
Starting to look like upgrades between major kernel version may be an issue.
