By default the processor itself supports one wire. I loaded the slave module first and then the master module. For reading/writing to the device, the 1-wire driver provides a binary attribute inside the sysfs. In the case of the DS2431, this attribute is placed under the following path and with the following attributes ls /sys/devices/w1_bus_master1/bus/devices/2d-0000015db4d0/ The 2d-0000015db4d0 is the unique device id that will appear after the master detects the slave device. In my case I connected two devices in parallel but only one device is detected in sysfs. I googled but I didnt find any clue why the 2nd device is not detected. Did I miss anything? Thanks in advance for your help</SPAN></BODY></HTML> Thu, 12 Apr 2012 05:02:26 GMT sountharya1z 2012-04-12T05:02:26Z One wire problem https://community.nxp.com/t5/i-MX-Processors/One-wire-problem/m-p/153519#M1681 <HTML><HEAD></HEAD><BODY><SPAN>Hi, I am working with 1kb EEPROM DS2431 one wire device in IMX51 processor.
