Hi, I recently work on FPGA of DE2-115.

I tried to modify the demonstration, DE2_115_SD_CARD, provided by Terasic to write the data into SD card.

However, none of my method succeeded.....

Can you share with me how to use the "University Program SD Card IP Core" to write data into SD card?

Or just create a text file in SD card?

Any of your help is highly appreciated.

Thank you very much!!
