https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195009 --- Comment #7 from Ian Lepore <ian@FreeBSD.org> --- You need to reset the bus after changing the speed with sysctl to make the change take effect, i2c -r -f /dev/iic#. I'm waiting for a review from the documentation team before I check in the new manpage that tells you that. :) Also, I forgot to mention in the commit message, but I checked the bus speeds with an oscilloscope on a beaglebone white to verify that the new divisors are correct. I also verified that i2c eeprom devices can be read at all 3 speeds. I don't have hardware to test omap4. -- You are receiving this mail because: You are the assignee for the bug.
