Honored Contributoruart RS232 communication problem
Hi all,
I have cyclone2 dev kit. I tried running uart program given in the Embedded Peripherals pdf but there is no output on the hyperterminal. I have set the baud rate to 9600 and i have changed it in the system.h also. But the program is neither taking any input from hyperterminal nor sending any output. What could be the solution for this? Do I need to modify the code? Even this simple code is not working! int main (void) { char* msg = "hello world"; FILE* fp; fp = fopen ("/dev/uart_0", "w"); if (fp!=NULL) { fprintf(fp, "%s",msg); fclose (fp); } return 0; } Thanks, Nishant8 Replies
Altera_Forumwhen i run the program on DE2 to do the ETHERNET test ,I also meet these warnings . NOw i havn't run a program in DE2_demonstrations .

Actually I am able to run other programs like using jtag_uart_0 but the proble is with using uart.
Whare to set startup type to ROMRAM? Thanks - Altera_Forum
The warning says The simulator cannot simulate buttons, LEDs, and other physical things. You can ignore these messages.
have you set the startup type to ROMRAM - Altera_Forum
What is QUARTUSII project? What is the file extension? and what do I need to do to modify it?
Thanks for the reply! - Altera_Forum
Thanks for the directions. I get these warnings when I try run in Instruction Set Simulator. Do I need use SOPC builder to correct these.
Please guide me further. Thanks. Warning : SOPC Builder system component led_red is not supported by the simulato r.

simulator doesn't need any hardware support.
if it doesn't run in simulator , doesn't take i/ps and o/ps there is something absolutely wrong in the way in which you incorporated your UART in the VHDL/verilog project. if the QUARTUSII isn't giving any kind of errors while compiling your project, atleast you can check the warnings to get an idea. I think it is something basic that you are missing out here - Altera_Forum
No, I tried running the program on simulator but it doesn't run there either. May be it needs some hardware support to run.

Have you tried simulation? Is it something like it is working fine in simulation but not in the practical case.
