Anyone have luck with the ChronoDot (D3231) on Raspberry Pi?
I have a RPI B+ (rev 1), tried with HEAD r277133 and r279488 without luck.

a) tried the DS1307 program from Vadim Zaigrin, without success.

I have VCC pin 1, GND pin 6, SDA on 3 and SCL on 5.
trying /dev/iic0 and /dev/iic1
Any help/suggestions apprecitated.
Thank you,
