Looking for examples of read + writing to flash memory

Hi,

I have the DE1 board, with 4MB flash. I am looking to read and write to it using verilog.

I do NOT want to read/write to it using NIOS, C++ or some external program like the DE1_ControlPanel.

I have downloaded the altera university program Flash Memory IP Core, and have tried to build a project that instantiates Altera_UP_Flash_Memory_IP_Core_Standalone. But Ive had no success read/writing to the flash chip.

If anyone has some easy to follow examples or created a top module that instantiates and calls this core properly I would be grateful if you could share.

Thanks
