[zd1211-devs] Where exactly I am supposed to place the zd1211 firmware on filesystem?

[Nazim Khan <nazim.asad@gm...>]

Hi,

I am trying to bring up Zydas1211 chipset based AirLink card on my ARM
based system
with 2.6.18 kernel. While loading the zd1211rw.ko module it gives the
following error.

usb 1-1: Could not load firmware file zd1211/zd1211b_ub. Error number -2
zd1211rw 1-1:1.0: couldn't load firmware. Error number -2
usb 1-1: reset high speed USB device using musb_hdrc and address 2
zd1211rw: probe of 1-1:1.0 failed with error -2
usbcore: registered new driver zd1211rw

The error number "-2" is -ENOENT (No such file or directory).

I tried placing the firmware
/libs/firmware/zd1211/
/zd1211/

but it did not work? Where exactly this firmware is supposed to be.

TIA
Nazim

mine is in /lib/firmware/zd1211/ (note the s in your path, maybe a
typo).

Check your udev config, you should have a line like
SUBSYSTEM=="firmware", ACTION=="add", RUN+="firmware.sh"

My /lib/udev/firmware.sh has FIRMWARE_DIRS set to /lib/firmware.

Hi Sebastian,

Thanks for your response and providing some pointers. I see that in my
RFS, the entire "udev" stuff is missing. Both from /etc and lib folder.
(this is the embedded distribution I got from our hardware platform vendor).

Any specific step to set it up (any doc anywhere other than man page)?
Does udev has some dependency on kernel too?

regards,
Nazim

Hi Sebastian,

Yes, we are talking about 2.6.18. But looks like our ditributor gave
us the rootfs which is minimal as we are working on embedded system.
I'll try to build the complete RFS
specially w.r.t. udev and then try it out.

thanks
Nazim
