Hi I have tried to construct a simple circuit using a MAX232CPE and a DS2480B and hook it up to the owserver. When running on a usb-serial adapter I got random errors, for example Segmentation fault, Trace/breakpoint trap, Floating point exception and Illegal instruction. I thought it might have to do with the usb-adapter so I connected it to a real serial port but the result were the same.
I have checked the mailing list and made sure that VDD, VPP and POL of the DS2480B are connected to +5V. I get the segfaults with or without anything connected to the 1-wire pin and with and without parasite powered thermometer connected. The RX232-circuit seems to work as it can do loopback to the pc on the UART-side. On the software side I've been trying kernel 2.6.22.14 and 2.6.28.1, the lastest release of owfs 2.7p13 as well as the lastest in cvs as of today 2009-02-05. The usb-serial adapters are pl2303-based. In dmesg I get lots of errors of this kind on the computer with kernel 2.6.28.1: owserver[15073] general protection ip:804de21 sp:b75de328 error:0 in owserver[804d000+1000] Any ideas what could be wrong?
