Philby, Is this a generic solution which works on DM365 as well? Why did you do the following command? #./i2cset -y 0 0x50 0x00 Using the Arago tree kernel I was able to reproduce the issue by doing ./fbdev_loopback -i2 -d0 and then press Control C. I am not sure why you run the command ./i2cset -y 0 0x50 0x00 Murali Karicheri Software Design Engineer Texas Instruments Inc.
