:( unfortunately the Xscale is not connected directly to the I2C devices on
board, that is why I have to implement the I2C core in FPGA, I use FPGA as
glue logic and now is the problem of chose the easiest way.

Driver or core, that is a question now :)

Hi !

I need to create a I2C controller in FPGA and  write or rewrite a I2C driver
for linux running on xscale.

Any idea how?

If I use allready written standard  HDL code and rewrite the driver or
rewrite a HDL code and use linux driver in I2C package?


thanks, Sasa
