Qsys: UART AVALON SLAVE

Guys, 

 

I'm approachinng to Qsys and I take a project from David H. and I added the UART AVALON SLAVE.

I would use the "jtag_master" to test the "uart_0". 

 

My first goal is able to send to terminal some characters thru System Console inside Qsys. 

 

I open the UART AVALON Datasheet and look at the register Mapping:

and I add this code inside tcl script: 

 

proc uart_test {{len 0x2F}} { puts for {set i 0} {$i < $len} {incr i} { set addr 0x02000001 set data puts "Info: write at $addr, $data!" jtag_write $addr $data } return }  

 

But I have no success to send some byte to my serial port. 

 

I think it could be a good "debug" system and for newbee like me very usefull to start. 

 

Best Regards, 

Alessandro
