My board is ordb2a-ep4ce22 board,and i use the rbf image available at ftp://ocuser:ocuser@openrisc.opencores.org/virtualbox-image/orpsoc.rbf.servel days ago it can work with write or read block,but today it just can read block!I find that no matter how I try,it is always giving me a fifo flow error.The TXBD count would decrease every time I write block.If error is occured,read block turn to error,too.Could anyone give me pointers as how to go about this?
Thank you very much!
