Cover SYNOPSIS. I loaded i2c-dev and i2c-core modules. 21. This installed i2c-tools as well, which we’ll use a little later to locate i2c devices on the system. The Linux offers a widely used i2c toolkit, and it works as always until we encounter this problem when trying to access ADV7619. -f Force access to the device even if it is already busy. i2c-tools has the following apps: i2cdetect (used to detect slaves address in the bus) i2cdump (used get a range of values) i2cget (used to get a value) i2cset (used to set a value) Please refer to each app -h option to see its usage.

And I see web references that Linux I2C will respond with EREMOTEIO (as seen in strace output in my original post) when the I2C device does not respond with ACK, so that would correlate. This assumes that the device automatically increments its internal pointer register on every read, and supports read byte transactions (read without specifying the register address, "Receive Byte" in SMBus terminology.) 1) Setzen des Control-Registers für Channel0 (i2cset -y 1 0x28 0 0x80) mit dem Wert 0b10000000 2) Das Abholen der Werte erfolgt durch einen Read-Befehl, worauf der Baustein 2 Data-Bytes sendet.
