Hi all, trying to read registers on the BAE 910 chip I get a segmentation fault in owhttpd (see below) and owfs. I have no problem reading other devices on the bus.
When I try to read the BAE chip using owfs: ls /mnt/1wire/FC.000000000022/910 it's the same, owfs is crashing with the same debug information. owhttpd and owfs are connected to the 1wire bus via owserver, which is running as: owserver -p 2125 -d /dev/ttyS0 owserver is not affected of the crash. My setup is: System: Ubuntu 8.04.4 LTS Hardy OWFS: compiled from owfs-2.8p2.tar.gz Bus master: LinkOEM (same as Link45) at /dev/ttyS0 Any hints are welcome as I'm not used to debug c programs.
