where should I change the address range in Qsys? In the document "SD_Card_Interface_for_SoPC_Builder.pdf" they write I should change it to 1024 bytes. Is this way right? Component Library-> Edit -> new windows opens -> Component Editor -> Interfaces -> avalon_sdcard_slave -> Parameters -> Explicit address span: 0x00000400 okay? :-) AND I can't find a button or input field where I can set Tco and Tsu?!? Thanks in advance!
