Thank you for finding this!
The locking was needed for uClibc that apparently didn't have a thread
safe snprintf implementation.

Aaahh.
I finally managed to solve the w1-gpio master isse with owfs...
After some "deep-digging" I noticed just a plain typo... in
module/owlib/src/c/ow_w1_addremove.c
The uclibc mutex was "re-locked" twice instead of unlocked...
Why is it necessary to lock the access to "standard lib
A quick test shows that w1 works with DS2490 (usb) under i386
(actually 64 bit) in the current version.
Can you try ./configure --enable-owtraffic
and run (as root) with the --debug setting?
That will help start the debugging process.

Ok, before I explain the specifics, let me review what I know of w1.
Much of this was worked out consulting Evgeniy Polyakov, the kernel
developer responsible for the system.
w1 (now called wire) was designed as part of the hardware sensors
system, with a wire kernel module, and subsystems support
After some more digging through kernel code (connector, w1_netlink
etc.) I think I found some discrepancies in few includes.The problem is I'm not too familiar with the details of connector/netlink programming
(netlink groups, ids, sequences etc)Ok, I'll try to explain my findings in short words.I'
Hi Paul!Thanks for answering!Absolutely! If you have
anything that could help me I would be very grateful.you can send what you suggest to my email - [email protected] would kindly ask you
if you could "reveal" me any more "specifics" regarding the "usage/linkage" of the owfs system to the kerne

I certainly know the internals.
I don't know if it's endian sensitive. I used the kernel headers from
the netlink for the netlink information. Can I send you an
"instrumented" owfs version that will print out more detail?

Hi again!
After some more frustration I recompiled the kernel and all modules with
dynamic debugging enabled (dynamic_printk) and after re-flashing the
board enabled all debug messages for wire.ko kernel module (w1-master
kernel module).
After starting owserver/owfs... I thought the wire wo
Yeah...
to be honest, I intend to use the w1 + ofsw on another (but similar)
platform with the same/identical software.
Anyway, the target platform has just ONE UART which is used for the
console. There is no USB either.
But there are some free gpio pins...
On the other hand, yes, it would be
wouldn't it be easier to use an UART and an UART to 1-wire conversion chip?

Actually you're heading the right direction completly. Why not post

The goal is to make owfs work with the kernel w1-gpio-master driver.
I'm trying to setup the owfs on an
