localhost:3333: A connection attempt failed

[YanAyon]

Hi,

I wanna blink a led on port PA0 using the Olimex sam7-ex256 and the arm-usb-tiny-h. after building the project it seems all is going well but by debugging I get this:

source .gdbinit
target remote localhost:3333
localhost:3333: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
monitor reset init
"monitor" command not supported by this target.

"monitor" command not supported by this target.
monitor arm7_9 fast_memory_access disable
"monitor" command not supported by this target.
symbol-file main.out
monitor flash write_image erase unlock main.bin 0x00100000
"monitor" command not supported by this target.
monitor sleep 100
"monitor" command not supported by this target.
monitor arm7_9 fast_memory_access enable
"monitor" command not supported by this target.
monitor reset halt
"monitor" command not supported by this target.
thbreak main
No hardware breakpoint support in the target.
continue
The program is not being run.
kill
The program is not being run.


Can someone tell me what's wrong or what I must do?

here is my main.c:

What have you got on port 3333?

Did you mean to use OpenOCD?  You need to config & run it if so.

Hi John,

and thank you for your reply. I really don't understand your question about what I have got on port 3333. But my debug configurations in option "Commands" seem like this:
'Initialize' commands
target remote localhost:3333
monitor reset init
monitor arm7_9 force_hw_breakpoints enable
monitor arm7_9 fast_memory_access disable
symbol-file main.out
monitor flash write_image erase unlock main.bin 0x00100000
monitor sleep 100
monitor arm7_9 fast_memory_access enable

'Run' commands
monitor reset halt
thbreak main
continue

Did you mean to use OpenOCD?

Yes I'm using OpenOCD and when I run my external tool( ARM-USB-TINY-H) it works problem-free. OpenOCD is already configured and here is my project.cfg:

Code Select Expand

#
# Flash AT91SAM7S memory using openocd
# and a FTDI FT2232-based JTAG-interface
#
# created by Martin Thomas
# based on information from Dominic Rath
#

#daemon configuration
telnet_port 4444
gdb_port 3333

gdb_memory_map disable
gdb_flash_program enable

#ARM-USB-TINY doesn't support adaptive clocking
adapter_khz 1000

source [find scripts/board/olimex_sam7_ex256.cfg]

When it is running I get this:
interface uses the same layout as configs that were verified. Please report your
experience with this file to openocd-devel mailing list, so it could be marked
as working or fixed.

Do you think perhaps that some programm is using the port 3333? How can I check this port?

I look forward to your support.

Yan

[YanAyon]

Any Ideas??

[JohnS]

You can check with your OS what is using which ports.

John

[YanAyon]

Hi John,

and thank for your reply. I have used portchecker from this website: http://portchecker.co/check to check the port 3333. It told me that the port is closed. So, what can I do?

Yan

[JohnS]

For what you look to want you need both gdb & oocd running.  Your info above suggests you want gdb on 3333 so find why it isn't.

Hi John,

I uninstalled and reinstalled OlimexODS. After I changed the location of openocd to bin-x64 because I'm using a 64-bit win7 and the arguments, I created a new empty project and imported the files from the existing example project SAM7-EX256-cdc_FLASH. After that, I duplicated the debug configurations of the SAM7-EX256-cdc_FLASH and renamed it. After done that, I built my project, ran ARM-USB-TINY-H and by debugging I got this:

The microcontroller was flashed but I couldn't run the programm step by step in Disassembly because it was empty. Do you have any ideas about?

[JohnS]

Using a recent (& 64-bit) OS but ancient other tools looks unwise.

(Using Windows at all is unwise but that's another issue.)

Even the old tool is telling you to do something else.
