Using Xillybus Device as PCIe-I2C Bus Adapter
Posted:
Hi,
I'm interested using a Xillybus device to interface with I2C bus adapter logic in the FPGA. I would like to access this I2C bus a Linux root via i2c-dev interface. I am considering using the Opencore I2C driver which already has a Linux I2C bus driver written, though I'm open to other solutions here - the simpler the better. Is an I2C bridge something that has been done before with Xillybus? Do anyone have any pointers on adapting existing Linux I2C bus drivers to work with Xillybus devices?
The I2C device would not be the only Xillybus device, I'm using another device for high-rate data streaming, and I'd like to keep the existing Xillybus driver in tact.
Thanks,
Mike
