16 years agowell, I'm still stuck
I thought I'd see something like this --- Quote Start --- Freeing unused kernel memory: 676k freed (0x1f6000 - 0x29e000) mmc0: new SD card on SPI mmcblk0: mmc0:0000 TWTTI 124672KiB mmcblk0: p1 p2 --- Quote End --- on boot, as ashown in nioswiki so I thought of a few possible problems 1. pin assignments 2. IP core not configured as should 3. driver not loaded now I'm down to either it's an IP problem or driver problem so just to make sure again it is Altera's SPI (3 wire interface) IP, right? not someone else's similar IP? and if so could someone show me the right configuration? Thanks again, Asaf
