pausing target processor: not responding

hi all,

i hav build a system in sopc builder using nios ii cpu, jtag_uart, esps_flash_controller, ddr_high_performance_memory_controller, tse_mac, sgdma_rx, sgdma_tx, flash_tristate_bridge, ext_flash, and an onchip_memory. i managed to compile it successfully.

i downloaded the hardware image into fpga and now am trying to run a simple hello_word program on nios ii processor. but it is not happening.

the following message is being displayed in the console. . .

using cable "USB-blaster [USB-0]", device 1, instance 0x00

pausing target processor: not responding

presetting and trying again : FAILED

leaving target processor paused

if anybody knows why this is happening pls help me. . .

thank you. . .

    hi,

    thank you cris and kbs972 for ur replies.

    i rebuilt my system, i removed ext_flash component and instead of ext_flash i set on_chip memory as reset vector of nios ii.

    now pausing target processor problem doesn't exist.

    but nothing is getting printed in the console

    am getting the following messeges:

    nios2_terminal: connected to H/W target using UART on cable

    nios2_terminal: "USB-Blaster[ USB-0]",device 1,instance 0

    nios2_terminal: (use the IDE stop button and Ctrl-C to terminate)

    but hello from nios ii is not getting printed.

    pls help me.

    thank you.

    Check if you selected UART as stdout device.

    Also make sure your target is running; if you have a spare PIO or a LED you can toggle it to monitor program execution.

    hi,

    yeah i have set stdout as jtag_uart

    and for toggling LED where i should write code, in nios or in quartus. . .??

    In Nios program.

    Say you have a spare PIO port named led_out, possibly connected to LEDs.

    Then you can toggle the first pin by calling periodically this function: 

    
# include "altera_avalon_pio_regs.h"
void PIO_pin_toggle(void)
{
   alt_u8 pio;
   pio = IORD_ALTERA_AVALON_PIO_DATA(LED_OUT_BASE);
   IOWR_ALTERA_AVALON_PIO_DATA(LED_OUT_BASE, pio ^ 1);
}

    This way you can easily monitor if your Nios program starts, keep running or hangs at some time.

    Regards

    Cris

    Maybe the demo project was created with a different version of the dev tools.

    Did you create a new project and then added demo source files, or did you import an existing project?

    Also check if your Nios projects points to the correct sopc system and possibly regenerate it.

    no cris those demo files are created with same version of dev tools. . . when i installed those software files they appeared in the nios ii IDE similar to other templet programs (e.g.hello world)

    i selected that templet and selected build project thats all. . .

    I know this is some 8 years late but just ran into it. In my case I hooked up a memory mapped slave (other than the internal bram) to the instruction master rather than data master of the nios2 in Qsys.
