hello,everyone
In the DE2_SD_Card_Audio project, the designs uses a Nios II system to demonstrate how to read from the SD card.But the software in NIOS II has not involved to the file memory operation,only has realized the signal succession.Now I am making a topic about the video gathering and return back,needs the video which gathers to save to the SD card ,and reads out the video from it. I did not know how to edit the code about SD card , who has SD card examples? Thanks!Link Copied

Jdhar had ported a SD driver, and you may port it to your board.

When I search "SD" on nios2 uclinux forum.An error takes place like this:
One or all of your search keywords were below 3 characters or you are searched for words which are not allowed, such as 'html', 'img', etc, please go back and increase the length of these search keywords or choose different keywords. Actually,I can use uc/fs file system,I think it is easier than uclinux.I have already downloaded the uc/fs code,but in the FS\DEVICE folder there has no driver for SD/MMC NAND Flash.Now I need to use the SD card, but I did not know how to write the driver, who can provide this driver? Thanks!- Mark as New
