General TC > Tiny Core Netbooks

Acer Aspire One with AMD C50 - no internet connection or audio available

<< < (12/17) > >>

I am also having sound and wireless problems on my Acer Aspire, as well. A partial solution for sound is to add a file .asoundrc to your home directory. Contents below. This allows playback. Not sure if it works with the microphone.

I have not been able to get wireless to work on this netbook with TC 4.0. wl.tcz does not appear in the 4.0 repository. Copying from another repository did not work. Perhaps I am missing something in the 4.0 release


.asoundrc contents:

pcm.!default {
   type plug
   slave.pcm "dmixer"
}

pcm.dmixer  {
    type dmix
    ipc_key 1024
    slave {
      pcm "hw:1,0"
      period_time 0
      period_size 1024
      buffer_size 4096
      rate 44100
   }
   bindings {
      0 0
      1 1
   }
}

ctl.dmixer {
   type hw
   card 0
}

best regards,

I see broadcom have finally got around to saying this:


--- Quote ---Problems with > 3.0 kernels
===========================

A problem has appeared with recent 3.X.X kernels where the wl.ko driver loads but is inoperable.

The issue is related to the new bcma driver which is incompatible with this driver. The bcma driver
is analogous to the old ssb driver and bcma needs to be removed and/or blacklisted before wl
can function properly:

See if any relevant drivers are loaded:
$ lsmod | grep 'b43 \| bcma \| wl'

If any of these are installed, remove them (as root):
# rmmod b43
# rmmod bcma
# rmmod wl

Now load the new wl driver:
# insmod wl.ko

wl.ko should now be functional.

To blacklist the bcma driver and prevent it from loading in the future:
# echo "blacklist bcma" > /etc/modprobe.d/blacklist.conf
--- End quote ---

I'll try to to have a look at it this weekend.

In  the meantime, maybe b43 or ndiswrapper will work?

Hi juanito,

Thank you for the wireless advice. I will give it a try as soon as I can and report back.

Best regards,

wl uploaded to 4.x repo

..I needed to blacklist b43, bcma and ssb for it to work

even the latest version is outdated - there are many newer broadcom devices not included

sci_fi:
Hi juanito,

Thank you for uploading wl.tcz. I am making some progress.

After manually removing ssb, bcma (this one is there) and b43, I modprobe wl. At this point I activate eth1 as a wireless interface and see wireless networks. I appear to be able to connect. This driver is flaky with this kernel but I am still experimenting.

I created a file /etc/modprobe.d/blacklist. Contents:
blacklist bcma
blacklist ssb
blacklist b43

This file apparently doesn't work as bcma is still loading. Can you advise me on this? Perhaps, the tiny core blacklist file is located someplace else.

Also, another question. The processor on this netbook is 64 bit. The wl driver is in the 3.0.3 directory, not the 3.0.3-64 directory. It seems to work, but should a 64 bit version be used instead.

More as I get a little further.

Thanks, again.
