Dear Balanga, I run 11.2 on my Sheevaplug (armv5 also). uname -a FreeBSD sheeva2.klop.ws 11.2-RELEASE-p4 FreeBSD 11.2-RELEASE-p4 #4 r339336M: Sat Oct 13 23:31:51 CEST 2018 builder@rpi3:/data/src/obj-11.2/arm.arm/data/src/11.2/sys/SHEEVAPLUG arm It has a ports checkout using portsnap. And that works pretty well. Just do: portsnap auto cd /usr/ports/shells/bash (or whatever port you wish to install) make install make clean I think that is the most simple approach for you to go forward. Regards, Ronald. PS: Sorry for top-posting, my current mail client does not help in this very well.

Observing the bus with a logic analyzer shows, that between start condition and the address write there is a 10ms pause. Then the address gets written correctly and the device answers ACK. The I2C-clock is 100kHz which is confirmed by logic analyzer. I'm assuming that this long delay between start condition and address write causes this error, but i do not find any problem in the i2c driver(iicbus/twsi*). I've crosschecked the board with the default Linux image, and I2C works there without problems and there is no visible delay between start and addr-wr. Any ideas? -- Manuel
