kernel modules compilation

[spewak]

Hi

I just compiled some kernel modules for my D6500 and when i try to load for example snd-usb-audio.ko it fails with "insmod: can't insert 'snd-usb-audio.ko': unknown symbol in module, or unknown parameter" . I am using toolchain from samsung and firmaware sources. I try to compile simple program "hello world " and it works fine on tv. What am i doing wrong?

Regards.

Code: Select all

insmod snd-usb-audio.ko
dmesg | tail

what is output?

Can be you`ve used wrong kernel config

[spewak]

This is dmesg output:

Code: Select all

snd_usb_audio: Unknown symbol snd_pcm_set_ops
snd_usb_audio: Unknown symbol snd_pcm_hw_constraint_list
snd_usb_audio: Unknown symbol snd_device_new
snd_usb_audio: Unknown symbol snd_pcm_rate_to_rate_bit
snd_usb_audio: Unknown symbol snd_card_disconnect
snd_usb_audio: Unknown symbol snd_card_create
snd_usb_audio: Unknown symbol snd_pcm_period_elapsed
snd_usb_audio: Unknown symbol snd_usbmidi_disconnect
snd_usb_audio: Unknown symbol snd_pcm_format_width

Hmm i think that the modules are dependent of each other .. am i right??

EDIT

I try to load another module ftdi-sio.ko - this is module for usb - rs232 converter it fails too with he same error but dmesg shows nothing

EDIT

heheheh

what was the problem?

[spewak]

It was load sequence. Should be:

Code: Select all

insmod soundcore.ko
insmod snd.ko
insmod snd-mixer-oss.ko
insmod snd-seq-device.ko
insmod snd-rawmidi.ko
insmod snd-timer.ko
insmod snd-usb-lib.ko
insmod snd-seq.ko
insmod snd-hwdep.ko
insmod snd-page-alloc.ko
insmod snd-pcm.ko
insmod snd-usb-audio.ko

I must analyze dmesg output for my sound card, and prepare alsa for tv.
