Mapping SPI flash memory span to avalon bus.

Hi All, I have a board using an SPI serial Flash hooked on the FPGA. I would like to map the whole span of this memory on the avalon bus for making it available to the Nios (some strings in tha...

It gives access to a SPI based flash memory, but doesn't provide a full memory map on an Avalon bus. It provides registers that you can use to send instructions and read the results, so you need a piece of software to read and write a specific part of the memory. This is provided in the driver.

If you really want to map the flash contents into the Avalon memory space, then you'll have to write your own component.
