I am currently doing a project using altera De0 nano SOC board. I have modified the GHRD project Qsys according to my requirement. I need to route HPS I2C-2 peripherals to FPGA side to control an external peripheral. I have modified the dtb and rbf files and loaded in the SD card but i am facing some problems.
1. I guess i need to generate the preloader again for the modified qsys. I am not getting how to do that. Please help me in that.
2. What other files i need to update in my SD card for the modified design to make it work properly.
After modifying the GHRD, Compile Quartus Project
We have to update preloader and u-boot i.e Partition 1 & Partition 2 of sd card
Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

Thanks for the solution. I have followed the steps and now my I2C-2 controller is active but still after some time it gives an error "i2c_designware ffc06000.i2c: controller timed out" I am not able to find out what is causing this error. Is there anything i need to add in my device tree to rectify this problem?
