Hi, I prepared a two fixes related with 1wire and DS2408. In short the problem was that a single DS2408 slave was properly setting the output value to a channel access write but the command was returning error. Moreover when there was a write of a 0xff value (all inputs off, there was also no problem - it's now also understandable for me after looking at the transmission log) ;) This problem doesn't occur on a multidrop bus.
Finally I was able to catch the problems recently after analyzing the oscilloscope waveforms in PulseView. After those fixes all is now working perfectly fine - no matter if it is multidrop or single slave bus :) ps. if you are merging this please also take into account a patch which I've sent recently but it is still not merged: https://lore.kernel.org/lkml/[email protected]/ regards, Mariusz Bia??o??czyk | xmpp/e-mail: [email protected] https://skyboo.net | https://github.com/manio Mariusz Bialonczyk (2): w1: ds2408: add a missing reset when retrying in output_write() w1: fix the resume command API drivers/w1/slaves/w1_ds2408.c | 13 ++++++++----- drivers/w1/w1_io.c | 11 +++++++++-- 2 files changed, 17 insertions(+), 7 deletions(-) -- 2.19.0.rc1
