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.

b) tried i2cscan from Winston Smith,

only get errors. ie,

ioctl(I2CRDWR) failed: Input/output error

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,
