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....

OK, So the problem was trivial, the i2c clock was connected to SPI clock :). I don't know how much time i have spent on this...
