Soekris 4801 error led control?

Hello,

I'm using voyage linux 0.8.5 and I am trying to make the error led work on a
Soekris 4801. So far as I can tell there is a kernel module present for it,
but there is no device present in the /dev. I have tried modprobing but no
success either. Is there any way to get this working?

Don't have any experience with Soekris.    With the ALIX LED drivers
loaded, there are link files in /sys/class/leds directory by the names
alix:1, alix:2, and alix:3.

Is there a similar file structure in your case with Soekris?

Re: Soekris 4801 error led control?

Hello,

I have no experience with the 4801 but I do have with the 5501. It's
driver was modified by ON7LDS for the 5501 based on the 4801 driver by
Meduna/Hejl. I created a minor patch for the ON7LDS driver to update to
to kernel 2.6.38. As its package also included the original 4801 driver
I also made a patch for that one just to get rid of the compiling
errors. I haven't actually tried the 4801 driver (I don't have one, but
it did compile fine) and I haven't compiled it for the 3.x.x kernel
Voyage currently uses, but I think there is a fair chance it compiles
and works without issues. It compiles not only the error_led driver, but
also that for GPIO, Temperature- and Voltage-monitors.

It does require you to recompile the kernel without a few options:
scx200 and scx200_gpio.

I included the patch made for the ON7LDS package. While that package is
intended to add 5501 support, it also modified the common.c/h files
required for the 4801. You can request the source from ON7LDS website.
Just run the patch and follow the instructions on Meduna's website and
from ON7LDS.

Please give a post back whether you got this to work.

Kind regards, Maarten
