Hi guys, the Raspberry Pi community is again having a hard time using owdir command. The problem is only with the w1 kernel module when the DS18B20 thermometer is connected directly to the GPIO pins of Raspberry Pi.
It is possible to read temperature with e.g. owread /28.1228EF040000/temperature12 but the owdir command "freezes" for about 30 seconds and it detects only some (or even none) of the 1-Wire devices. On 2015/06/28 marcin1j provided this explanation in the Raspberry Pi forum: After recent kernel w1 subsystem rewrite there's inconsistency between kernel and libow code. The official documentation still states that the last message from kernel should have ack=0. However, commit 8a0427d https://github.com/torvalds/linux/commit/8a0427d192e6043834414210dd14cc1289daff18 changed the documented behavior and the last message is no longer marked in such a way. He also suggested this patch https://github.com/marcin1j/openwrt-packages/blob/2163437b1afd7eeec486721fcf9503362c19b77c/utils/owfs/patches/101-fix-no-reset-routine-segfault.patch which worked fine at that time but it does not work anymore. I tested it with the latest revision of OWFS and the owdir command still does not work. And so did others in the forum. Here is the link to the Raspberry Pi forum for reference: https://www.raspberrypi.org/forums/viewtopic.php?f=44&t=98772 Does anybody have an idea what might be the root cause of this problem?
