I tried the latest git version from Feb 18th with several different kernel versions: 3.10.25, 3.12.28, 3.12.35, 4.1.13 The behaviour is always the same: It is not possible to read from the uncached EEPROM pages. However, it is possible to read the uncached temperature. On 19.02.2016 15:43, Jan

Hello, I'm using owfs to read/write the EEPROM of DS2436 and DS2433 devices. Mostly, this works nice and without problems. However, sometimes wrong data is stored on the EEPROM. I'm wondering what is the correct procedure to read/write form/to an EEPROM. Is it sufficient to use write() and write
