Can't Read Data from Custom componet (Avalon mm)

Luirro had posted a new verilog code that implements the smaller avalon mm slave device that we can make.

This is the HDL:

pastebin.com/yMBeTWPz

We conect it to the sopc, assigning the following pins:

Clk ==> clk_sink

irq_port ==> interrupt sender ==> irq

data_o ==> Avalon_Slave ==> readdata

read_i ==> Avalon_Slave ==> read

We have declare the ISR, but nothing happens, if we force the reading, only zeros again... The componet works perfect.

Any ideas?
