Hello. I want to write data from DDR to microSD. I saw microSD slots on Elbert and Mimas. Has anyone succeded to enable them? Do I absolutely need a soft-processor for this? I want to order Mimas V2, but the forum seems very quiet. Should I go for it? Thanks.
Hi rom, with a soft processor you can definitely do it. If you want to do it without the soft processor, you have to write the vhdl (or verilog or schematic) to implment the write and read functions from SD. You can try searching online, a good start point might be http://www.fpga4fun.com/SD1.html
Thank you very much. I started looking into the fpga4fun code. Are there any known libraries supporting SD for one of the soft processors? I have a successful experience with teensy 3.2 micro SD read/write and file creation. Is it on the same complexity level in a soft processor?
I didn't try it yet, but in the download section you can find the "Base System Builder Wizard" package, which should contain all the mimas v2 peripherals for soft cores
