Hi all,

I am trying to run the Altera Avalon Master I2C core from Nios II w/Eclipse.

I am accessing the core registers in memory using "altera_avalon_i2c_regs.h"

In the memory debug view, it seems that all of my calls are responded to in memory, other than IOWR_ALT_AVALON_I2C_TFR_CMD, which is the register that holds the data to be transmitted. It remains zero at all times.

Any ideas, or any recommendations on other I2C cores ?

Thanks,

rabee
