Hello_led can not run on Nios II/s core.

Yes, I have tried to use f/Core, the same result(bad on s/Core) happen.

-----------------------

First, I generated the system(I made the system with the standard HW design component, but I did not have lcd, so I deleted the lcd) with e/Core and everything is OK.(hello_led,memtest, board_diag and so on). I use Microtronix Cyclone Board(I borrow from other, the board was made in 2003. So Sometimes I think if it is the wrong of the board, but no infor from Microtronix said the revision of the board).

My system include sram/flash/sdram/epcs_controller/igor_mac/uart/led_pio/button_pio/sevenseg_pio/system_timer/jtag_uart.

-----------------------

Second, I regenerated the system only changed by s/Core. I tried the hello_led in Nios II IDE, it can not run.

I found in debug, the program stopped in the line 117. I set breakpoint and click Resume, but nothing run and program still stay at line 117.

I have no USB, no UART cable......, I only have on ByteBlaster cable connectted. I also have no LCD.

-----------------------

Then, I changed back to Nios II/e Core, the program can run again.

Here is my console information when I run the s/Core.

When I click Resume Button, nothing appears in console.

When I click step into Button, nothing happens and then I click suspend Button, it display Nios II ELF Debugger error.

"Target request failed: Failed to interrupt." and the program can not be suspended.

I do not try Q4.2 SP1.

I have no idea yet.
