Hi Paul, At this early phase of development I'm transferring the kernel via tftp and doing a nfs mount of the root file system. There are no users on the system; I'm running everything as root and will address permission issues later. My application will have a single process that will access the 1-wire buss via owcapi calls, so I disabled network support when I built owfs. Once owfs is mounted, the data I hope to read is static, so I'm only using Linux CLI commands over a serial console.
Here's a screen scrape of the owfs mount, which I think includes all debugging info: root@i:~$ modprobe fuse adbgko: mod:0x7f00b010 name:fuse core:0x7f000000 state:Coming fuse init (API version 7.14) adbgko: mod:0x7f00b010 name:fuse core:0x7f000000 state:Live root@i:~$ owfs --w1 --error_level 9 /mnt/1wire/ CONNECT: owfs.c:(96) fuse mount point: /mnt/1wire/ CONNECT: ow_avahi_link.c:(72) No Avahi support.

However, the 2.6.35 kernel is widely used in embedded systems and has had long term development. Both Freescale and TI produce embedded CPUs 1-wire bus masters in silicon that would use the w1 driver, so I'd expect it to function until contrary evidence is seen.

Can you run with debugging and send me a transscript?
