Hi,Is there a sd card controller for FPGA with nios II ? which is compatible for sd card > 2Go which offers FAT32 filsytem support. It would be greatful. which works :D in reading and writing. I know Elcamino makes that. But I wonder if there is an other. A long time ago I saw an "alternate sd card controller" ;) but not found anymore on the web (just one trace in google cache of nios forum). It is just to write in a .dat file on a SD card. Does anyone have such an SD card IP ? Best regards
Probably.But no tracks on the web. "MP3 player design" includes partial of alternate_sd_card_controller but what about license ?
If you are ok with working on time-limited programming files, then you can request for evaluation license from slscorp website. The SD host controller is also tested on NEEK and there are reference designs available, but only on request basis. They analyze the project requirements and then release the reference design. For generating POF file, you need to buy the core.
I have designed one,but support read only,include single block read and multiple block read with DMA. I will design the write part in future.
