SD Card UP Core

I cannot get the core to work. 

I have installed the newest UP cores in the Altera 12.1 directory as described. 

I have a working system without the SD Core, SOPC Builder works ok, 

system download fine and works as expected. 

When I add the SD core (I named it "sdcard"), the system generation is successful. 

I add it to the top level design (bsf method). 

But then I get always an error when compiling the design: 

Error (12006): Node instance "sdcard" instantiates undefined entity "Altera_UP_SD_Card_Avalon_Interface" 

What am I doing wrong? 

Regards, Friedrich

This thread: 

Using SD-Card reader on DE1 board (with Nios) 

showed a solution. It works for me, I had to copy the necessary *.vdl files manually in my project directory. 

THIS IS A NASTY BUG THAT NEEDS TO BE FIXED! 

Kind regards, Friedrich
