Hi, I found all the required information in the AM335x TRM pdf file. You
need to offsets for the I2C module you are using and the base address from
the memory map.
The programming sequence is all detailed in there under the I2C section.

Hugh,
Thanks for sharing your research.
Any chance you could also include a reference (ie where did you find this
info)?
Thanks

I forgot this from my previous post:
/* I2C2 register offsets */
#define I2C2_STATUSRAW (*((volatile unsigned int*)0x4819C024))
#define I2C2_CNT (*((volatile unsigned int*)0x4819C098))
#define I2C2_SA (*((volatile unsigned int*)0x4819C0AC))
#define I2C2_DATA (*((volatile unsigned
An update:
1. Enable the i2c peripheral clock:
#define CM_PER_I2C2 (*((volatile unsigned int *)0x44E00044))
/* Enable I2C2 clock signal generation */
while (!(CM_PER_I2C2 & 0x2))
CM_PER_I2C2 |= 0x2;
2. Setup the registers:
/*
* set I2C2_PSC register to 0x0B
* set
