Writing .txt file in SD Card - DE2

Hello Tiakumosan!

Thank you for your help!

I was using a hardware from altera, but i couldn't get any response from sd card! So I create my own hardware (following the instructions from the PDF from University Program), and Its detecting the SD Card!

Now I can use all the functions describe in the PDF! But...

But I am having problems with the FAT16, because the Core isn't detecting correctly the FAT16 file system. The function "lt_up_sd_card_is_FAT16" always return false!

How did you format your SD Card?

I formatted a 128Mb using "cmd" in windows (format E: /FS:FAT /A:2048 /V:SDCARD), doing it I get 2048bytes in each allocation unity and 65536 allocation units.

But I will need to store a large data, maybe I will need to use a bigger SD.

PS: Im using the 11.0 Altera UP!
