lattice fpga (machxo2-7000hc) sd memory interface

[favor7kim]

Hi All,
I'm working on development of Lattice FPGA & SD memory.
currently, i use an AK-MACHXO2-7000 FPGA Development board to study it.

I saw that there is example doc for SD Flash Controller Using SD Bus in lattice website
but they explained only wishbone host interace.. so i don't know how to access between FPGA and SD card using Mico8

is there anyone can help me?

There is a wishbone version of mico8 in the reference design package. If you do not want to use that version, you may go around emulating the bus, not that difficult. The wishbone spec may help you.
