I2c through FPGA not working on Cyclone V SoC Terasic DE1SoC board

Hi, I have connected the external I2C device through FPGA fabric to GPIO pins on the board. I'm using I2C1 (0xffco5000) I have created new preloader, uboot and linux distro, rbf and dtb file, etc....

Hi Settem, did you start with the GHRD project? I'm wondering if i2c would work with just changing the device tree and keeping the preloader and u-boot the same. I'm using GHRD as my base project. I want to connect an external device through the fpga fabric using hps i2c. My current problem is that I don't see any address returned from i2cdetect.

If you could share your project or device tree that would be great.
