Hi All,
I am using /dev/i2c-2 I2C driver from user space. Very often I face
communication issue on this bus.
- Something which is not working suddenly starts working if tried
repeatedly and vice-versa
Meaning of Works - starts communicating Meaning of Not Works -
addressing fails
Finally, I found the solution. Too faint. I should type echo
BB-BONE-LCD7-01:00A2 $SLOTS because it loads BB-BONE-LCD7-01:00A0.dtbo
file by default if I leave out 00A2 but there just exist *00A2, *00A3,
*00A4 files, no *00A0 and *00A1 files.
