Hii  

 

im using MSGDMA core to transfert data between FPGA and HPS-DDR3 on DE1-SOC board , i create my system using the Qsys but it still need the software which will activate the MSGDMA to start transfert. i read in this document "modular sgdma dispatcher core (https://forum.shelek.ru/index.php?action=dlattach;attach=7257)"about device driver files. 

the documment tells that The modular SGDMA dispatcher module provides the following device driver files 

 

where i will found this drivers ?

Hello 

 

I'm also looking for the right header file for a Nios program to test my QSYS system. Simply writing# include modular_sgdma_dispatcher.h causes an error.  

 

I expected the automatic BSP generation in NIOS Eclipse to include the driver and source files that I need to write a program.  

Apparently the mSGDMA was correctly identified in the BSP Editor, but somehow it doesn't recognize any driver.  

Can someone explain?
