Hi,

I got the EP2C35F672C6 work!

Take the verilog\niosII_cycloneII_2c35\full_featured example.

In SOPC Builder, change the reset address to 0x01000000 in ext_flash.

Take the default kernel config and just remove the Enhanced IDE/MFM/RLL support.

The kernel should compile without error.

Follow the Quick Start Guide for building a filesytem.

Upload fs and kernel to flash, then upload the full_featured.sof to the FPGA, reboot and kernel should boot directly. (the 7-seg disp should inc. every second)
