Nice work. I've been going through your code.
One basic question: What exactly is this adapter and which architecture
supports it?
Specific comments:
1. in ow_omap.c : OMAP_reset, are we missing something? I see a loop, with
fsync, but no body.
2. How big a send/recieve buffer does the
G'Day,
Nice work. I've been going through your code.
Thanks: I appreciate it!

It is not a true adaptor: Texas Instruments' OMAP development boards
have hardware support for 1-Wire. I

G'Day,
And the search algorithm:

Thanks to this document, I was able to eventually sort out the problem.
There were lots of small differences here and there between the way the
serial device works, and the way the OMAP bus works;
G'Day,
I doubt that you could skip the omap_reset() function since it's used
to address a specific device or the branch on the DS2490. (and reset the
1-wire bus which more devices need)
I have added an OMAP_reset() now; it is fairly simple, but there does
not seem to be much to do.
G'Day,
As I understand you have copied ow_ds9097.c and made your changes to it.
DS9097_reset() send a resetbyte 0xF0 and read a byte. If received byte
is 0xF0, no devices where found on the bus and it's therefor no use
to search for more devices in DS9097_next_both() where it exits later.
If
I seem to have completely missed something very important.
I decided to trace back, and it seems FS_realdir() is called by
FS_dir_seek(), however that function is never called either; nor is
FS_dir(). If I continue to follow the path, FS_dir() seems to only

G'Day,
I tried using owfs on my OMAP board, but even after I added basic
support for the DS2431, it did not list the device in /mnt/1wire --- I
am assuming that this is largely because of the unusual environment that
I am operating under. Given the report that I had a bad adaptor, this
