nios ii error, [FAT]the partition type(12) is not supported.

Hi all,

I have an Altera Cyclone V gx starter kit board, and I wanted to test some of the demonstrations provided. One of them, C5G_SD_DEMO, is supposed to provide an example of how a micro-sd card is read.

I have a 2gb micro-sd card, that says it is a FAT32 File System when I connect it with my PC. However, when I try to run the .bat demo, I get the following error:

[FAT]the partition type(12) is not supported.

[FAT]Fat_Mount fail

Failed to mount the SDCARD!

Please insert the SDCARD into C5G board and press KEY3.

This partition type comes up from one of the .c files included in the example, with the following code snippet:

// check file system

FirstPartitionEntry = 0x1BE;

//PartitionType = szBlock[FirstPartitionEntry + 4];

PartitionType = szBlock[0x01C2];

if (PartitionType == PARTITION_FAT16){

FAT_DEBUG(("FAT16\n"));

}else if (PartitionType == PARTITION_FAT32){

FAT_DEBUG(("FAT32\n"));

}else{

FAT_DEBUG(("the partition type(%d) is not supported.\n", PartitionType));

return FALSE; // only support FAT16 in this example

}

So, does anyone know what I can do? Keep in mind, with my previous DE0 board, reading a regular (not micro) sd card, that was FAT16 format, I was able to do that succesfully using University Program IP cores. So, I am somewhat confused as to why this demo is not working with a micro-sd card.
