you just need to ensure that there are drivers for the SPI device, i believe this is documenting on the nios wiki. you will need to map out the flash device config.c, i believe there are examples of that as well. Not much room in a spi flash though.

Hi dwesterg,
thak you again...you are probably right...this is not the right way... How much room could be needed in your opinion...from nioswiki (2c35_cf example) I see: vmimage (http://www.nioswiki.com/@api/deki/files/466/=vmimage) 1401.9 kB rootfs.jffs2 (http://www.nioswiki.com/@api/deki/files/470/=rootfs.jffs2) 3.38 MB niosii_cycloneii_2c35_full_featured_epcs_boot.sof (http://www.nioswiki.com/@api/deki/files/502/=niosii_cycloneii_2c35_full_featured_epcs_boot.sof) 821.46 kB I don't know exactly how big is the application sw that will run on the board but...what size do you have in mind (could be ok for you)???

Hi All,
a new question on EPCS.... I've enable SPI serial flash on linux kernel and added partitions for epcs....now I wanted to update netlist on epcs directly from Linux....it seems impossible...if I try cp/dd .img /dev/mtd4 (the device on which epcs belongs) I obtain can't open /dev/mtd4: permission denied .... I don't understant....If i try to mount jffs2 on epcs everything works well... Can someone help me to understand what is happening?? Carlo :)
