JetPack 3.1 kernel source tag problem

Autonomous Machines Jetson & Embedded Systems Jetson TX2

As mentioned by @snarky, this is the problem, configuration was incomplete. No CONFIG_LOCALVERSION was set, so modules cannot be found. Modules are searched for in:

/lib/modules/$(uname -r)/

I am going to guess you have:

/lib/modules/4.4.38-tegra/

…and that you do not have:

/lib/modules/4.4.38/

The only thing about config.gz which you must watch out for is that the suffix from CONFIG_LOCALVERSION is not set. So if the original “uname -r” is “4.4.38-tegra”, then CONFIG_LOCALVERSION must be set to “-tegra”, or all modules will be missing (optionally you can install a new module directory).

42

Yes I only have /lib/modules/4.4.38-tegra.

I will compile the kernel again.

Thanks @linuxdev and @snarky.

43

Hi, I re-compile the kernel without success.

add the CONFIG_LOCALVERSION

$ cat .config|grep CONFIG_LOCALVERSION
CONFIG_LOCALVERSION="-tegra"
# CONFIG_LOCALVERSION_AUTO is not set

now I have:

$ ls -l  /lib/modules/
drwxrwxr-x 3 root root 4096 Aug 12 22:10 4.4.38-tegra

but no luck

$ sudo rfkill list
Can't open RFKILL control device: No such file or directory

:/

44

At this point the modules are correct for location, and I would hope the config you started with is an exact match for the R28.1 kernel (with CONFIG_LOCALVERSION set). However, device special files which rfkill works with may still be missing. What is the output of “ls -l /dev/rfkill”?

45

do not exist

# ls -l /dev/rfkill
ls: cannot access '/dev/rfkill': No such file or directory
46

I’m not where I can check right now, but this means you don’t have the driver which produces “/dev/rfkill”, or else a udev rule missed renaming something (the former is most likely).

47

That shasum command does not verify that the kernel modules are in the correct place.
What does this print?

ls -lR /lib/modules/`uname -r`/

Do you have rfcomm.ko from kernel/net/bluetooth/rfcomm, for example?

48

yes, I have it

Do you actually load the bluetooth module or the wifi module?

I believe that the /dev/rfkill device is exposed by the kernel itself, only when some driver exposing rfkill functionality is loaded.

What does “lsmod” show is loaded?

50

I thought the wifi was working becase the ui show me the nearest networks
it show this.

# lsmod
Module                  Size  Used by
bnep                   17355  2
bcmdhd               7667931  0
51

Try “sudo modprobe rfcomm”. Then “ls -l /dev/rfkill”. It could be there was an error in detecting the need to load the module.

52

nop.

nvidia@tegra-ubuntu:~$ sudo modprobe -v rfcomm
nvidia@tegra-ubuntu:~$ ls -l /dev/rfkill
ls: cannot access '/dev/rfkill': No such file or directory
53

Does lsmod show rfcomm after modprobe? If not, what is the output of this (path should be correct to rfcomm.ko, but adjust if needed and comment if it differs):

sudo insmod /lib/modules/4.4.38-tegra/kernel/net/bluetooth/rfcomm/rfcomm.ko

NOTE: You may wish to monitor “dmesg --follow” during the insmod.

54

it shows with lsmod

$ lsmod
Module                  Size  Used by
rfcomm                 60062  0
bnep                   17355  2
bcmdhd               7667931  0
55

Then the device special file should show up unless there is a udev rule needed and the rule did not trigger. Does anything change when insmod and rmmod of that module and monitor “dmesg --follow”?

56

this is the demesg --follow
but the /dev/rfkill still missing.

Was the end of that dmesg including the moment you did the insmod or depmod or modprobe which inserted rfkill.ko? Seems it probably was, but do verify that the module shows up after this with “lsmod”.

Run this and see what shows up:

sudo -s
gunzip < /proc/config.gz | egrep '(RFKILL)'
exit

The command should produce this:

CONFIG_RFKILL=y
CONFIG_RFKILL_PM=y
# CONFIG_RFKILL_INPUT is not set
# CONFIG_RFKILL_REGULATOR is not set
# CONFIG_RFKILL_GPIO is not set
58

yes, it was.

This is my output. (i used zcat /proc/config.gz |egrep ‘(RFKILL)’ , instead)

# CONFIG_RFKILL is not set
# CONFIG_RFKILL_REGULATOR is not set

that means I have to recompile the kernel with those options?

Yes. Apparently your config lost the original default configuration items:

CONFIG_RFKILL=y
CONFIG_RFKILL_PM=y

If the original install had “/proc/config.gz” preserved these would “=y” (“y” implies a direct content of “/boot/Image”, and is not in a module…modules can load but if this is required then the modules will still fail). In this case where you lost the original configuration I would be suspicious of what else might be gone. You could try rebuilding the Image file with those as “y”.

It did work :) thanks for the patience
