So I have a Blackhawk XDS200 Debug Probe (TMDSEMU200-U) and I would like to use OpenOCD to debug on my target platform (IWR6483).
When I create a config file, I get the error:
Error: Can't find interface/xds200.cfg
The config file is:
source [find interface/xds200.cfg]
adapter speed 5500
transport select jtag
source [find target/ti_cc13x2.cfg]
Is there a reason it can't find this specific config file? When I change it to xds110.cfg, it doesn't give me this error (provided I connect the debug probe).
Alternatively, could anyone point me to this specific xds200.cfg file I could download?
Thanks!
XDS200 isn't one of the debug interfaces in https://github.com/openocd-org/openocd/tree/master/tcl/interface, so I don't think it is supported yet. I am also interested in OpenOCD supporting this debug probe!

Okay I have this issue for quite some time now because I never found a solution online.
I thought I will ask here and hope if someone else also encountered this issue (and with a little luck solved it).
So the expected behavior of those buttons starting with the left circled one is that the code is compiled, flashed and runs on the embedded hardware. The second circled one is the same as previous but will listen to breakpoints and start a gdb server.
When pressing the first button it will fail with the following error message:

mingw64 installed via msys.
arm gdb debugger (version 8.3.1)
If you have an idea what the problem could be, please let me know. I can keep using debug without breakpoints but it is annoying as hell that I just can't run.
Somewhere down the line a fix was needed for something.
# Enable semihosting at startup
# Dirty fix for https://youtrack.jetbrains.com/issue/CPP-7103

arm semihosting enable
Commenting the init and arm semihosting enable line fixed the problem.
Still weird it would work in debug configuration but not in run configuration. If someone knows why exactly. Please leave an answer in the comments or a post.
Happy coding :)
(Using STM32F767 microcontroller)
I have a remote debugging environment setup on a RPI using OpenOCD. I can connect to it just fine using GDB.
However since I am writing a bootloader I need to flash the firmware to a specific offset in flash memory. E.g bootloader starts at 0x800000 and firmware should start at 0x8010000 for example so the offset would be (0x10000).
This works fine locally using: mon flash write_bank 0 main.bin 0x10000
But since I don't have the main.bin in the RPI, is there a way I could use OpenOCD or GDB to specify my local file instead and that would be sent over the remote connection?
Note that I would not like to setup a FTP and thus am looking for an alternate solution.
Best regards
gdb should supports sending files to remote via the 'remote put '. But, when I try this in gdb, I get the response "Remote I/O error: Function not implemented". Seems like OpenOCD does not support this
Use "file" to select the file and then "load" will send the file across to the device.
Trying to debug my sample blink_led code on STM32L476 Nucleo-64 board but gdb can't connect to OpenOCD (connection drops almost instantly with error). I've read plenty of posts here and there but none of them helped. Tried adding commands to OpenOCD using -c but no change of behavior.
My code compiles both in Release and Debug config in Eclipse. I can flash the bin file using drag and drop (while the board has built-in STLink add-on) and looks the code runs perfectly on the board (LED blinks).
Cross compiling on Centos7 using the following versions:
Toolchain (gdb): gcc-arm-none-eabi-8-2018-q4-major
OpenOCD: 0.10.0-11-20190118-1134
As using eclipse didn't work I tried the command line,
(I'm not an experienced developer in this environment so I could not find any config file closer to my stm32l476 board than the stm32l4discovery.cfg, please let me know if there might be some issues using it)
./bin/openocd -f scripts/board/stm32l4discovery.cfg -c "init"
It starts,

So from those geeks who do it on a similar platform on a daily basis, can anyone help and tell me where am I doing wrong. Does missing any compile-time flag might result in this problem?
I'm scratching my head for a couple of days now so please let me have your hints.
One of the reasons may be that your STLINK firmware seems pretty old (STLINK V2J28M17 as your log shows). I suggest downloading the STSW-LINK007 application to upgrade the firmware. The software is a multiplatform Java application. It works flawlessly in Debian GNU/Linux.
Currently, I use another gdb server texane/stlink for my debugging task with GDB without any problem on some Nucleo and also custom boards. I use target extended-remote command to join the port of the server. Maybe you can try to connect with this command also under OpenOCD.
Try
telnet localhost 4444
it worked for me, while 3333 didn't
I'm using a Blue Pill board (STM32F103CB with 128kB of flash according to st-info --probe) via a clone ST-Link/V2 like this one. I've also tested using a genuine ST-Link/V2 like this one. I get the same result, described below, with both programmers.
My system is Linux (Debian LXDE) and I've installed OpenOCD from Liviu Ionescu's releases here.
My OpenOCD installation is working. As well as the Blue Pill I have a ST-Nucleo-F103RB board, and I can connect to it using OpenOCD. The command
openocd -f board/st_nucleo_f103rb.cfg
using the standard .cfg file that ships with OpenOCD gives

But I still haven't managed to connect to my Blue Pill using the ST-Link/V2 programmers. I've read everything I can find, including relevant sections of https://elinux.org/Category:OpenOCD and as much as I can personally digest of http://openocd.org/doc/. The following is where I've got to.
The .cfg file stm32f103c8_blue_pill.cfg doesn't work for me. It produces the output described below.
Based on what I've read I've prepared my own .cfg file at ../board/stm32f103.cfg. It says:
source [find interface/stlink.cfg]
transport select hla_swd
source [find target/stm32f1x.cfg]
#source [find board/stm32f103c8_blue_pill.cfg]
#reset_config srst_only
#reset_config none separate
Sources I've read suggest this should work, but it doesn't. Using my .cfg described above, it I can use either target/stm32f1x.cfg or board/stm32f103c7_blue_pill.cfg, and I still get the same output as described below. (In the case of both of those .cfg files I'm using the standard files, as shipped with OpenOCD.) I've tested with both of the reset_config variants shown above, and with neither. None of the combinations works.
The file interface/stlink.cfg that I'm using is modified. I've changed it to state the correct device_desc "ST-LINK/V2" and the correct vid_pid 0x0483 0x3748. (Both confirmed using lsusb.) So, ignoring commented lines, stlink.cfg reads
interface hla
hla_layout stlink
hla_device_desc "ST-LINK/V2"
hla_vid_pid 0x0483 0x3748
I've experimented with including the hla_serial of the programmer. Interestingly, lsusb can't find the full serial number. st-info --probe finds the serial number, but gives a slightly different number from the STLinkUpgrade firmware application. I've tried using both serial numbers. No difference.
Here's the command I give to OpenOCD:
openocd -s ~/stm32/openocd/scripts -f board/stm32f103.cfg
Notice that I have to set the path using -s for this command. With the ST-Nucleo-F103RB board, I don't have to do this. With the stm32f103.cfg file, however, if I don't set the path I get:
Error: Can't find board/stm32f103.cfg
in procedure 'script'
If I use the full command shown above, with -s to set the path, I get:

Here's the offending line 47 of stm32f1x.cfg:

I've searched for items on Stackoverflow/ similar about Error: invalid command name "dap". Using the OpenOCD documentation I understand that the dap create command exists, and roughly what it does. The most similar reported error I've found documented is at https://elinux.org/OpenOCD_Troubleshooting:_Invalid_Command_Name_JTAG, and the solution suggested there doesn't seem to be applicable because I'm not invoking interface/stlink.cfg from the command line.
I can't see what I'm doing wrong, and I'm now completely stuck. If someone can give me a steer I'd be really grateful. Sorry it's such a long post.
I just encountered this problem too. Officially there are no binaries provided, only source code. But there are two sites which release binaries was recommended by OpenOCD official:
1. Maintained by Freddie Chopin.
2. Maintained by Liviu Ionescu in Github.
I tried the latest version(OpenOCD 0.10.0 commit date: 2017-01-22 20:31:28 build date: 2017-01-23) released from Freddie Chopin's site, and I encountered this Error: invalid command name "dap" problem. But all *.cfg files I referenced had ran normally in my another computer with another OpenOCD binary(although I forgot where did I download that binary).
Not sure what went wrong, so I turned to the latest version(gnu-mcu-eclipse-openocd-0.10.0-11-20190118-1134-win64.zip) released by GNU MCU Eclipse(maintained by Liviu Ionescu), the error was gone, problem solved.
PS: I'm not saying there is a bug in Freddie Chopin's build, but if someone encountered this problem, maybe you can solve it by trying the version which is currently under actively maintained.
Agree with Wulfric, using standard install for OpenOCD
sudo apt install openocd
gave the "dap" error.
However the github version openocd-xpack worked correctly.
Using:
Linux clamps 4.15.0-66-generic #75-Ubuntu SMP ... as remote, Windows 8/10 as client target MIMXRT1010-EVK
I am having trouble getting a reliable debugging setup.
I have seen other threads in some forums across the net with a similar title, but the circumstances seem different.
Setup:
Linux (Xubuntu) 64bit
Eclipse CDT, Neon 4.6.0
"GDB Hardware Debugging" plugin from eclipse "install new software", configured to reset & delay 3sec, halt; load symbols (all checkboxes, no custom commands)
arm-none-eabi-gcc 4.8.3 tool chain
OpenOCD, recently downloaded, running in an own console, configured for my exact MCU with script provided by them & the st-link
STM32L476RG MCU with hard float, which is used.
ST-Link V2 debugger (stand-alone)
Now, there is a sequence with which I am, after some struggle every time, able to connect with the debugger, but stepping and reading variables doesn't work so clearly reliable that I'd trust what I see for a second.
But to even get to that point where the call stack would not be full of obvious nonsense entries and only very few of them, is tiring.
Example:
Flash the device with the firmware. This usually works without trouble.
Start openocd.
Start debugging in Eclipse.
OpenOcd shows connection, then says: "undefined debug reason 7 - target needs reset"
I regardless press the "resume" button in Eclipse to make the program run past the bogus top stack frame it shows.
Press "suspend" (still bogus in callstack), then "terminate".
Ctrl+C out of OpenOcd.
Manually (hardware) reset the stm32 MCU.
Restart OpenOcd.
Start debugging in Eclipse again.

undefined debug reason 7 - target needs reset
Now with some luck, I finally have a somewhat working debugger connection, for a while.
But this may as well need some repetitions.
Why the "press resume" in between when it's clear the connection is bad? Not sure, this seemed to increase the likelihood that in the next iteration I'll have the connection, a lot.
A maybe relevant note:
The MCU has an LCD connected to it and from that I can see when it resets.
For some reason, starting debugging in Eclipse will apparently not reset the device, although the reset checkbox is checked in the debug config.
If I open a telnet connection to OpenOCD in a terminal, and do "reset" there, the device does reset.
What could be causes for the odd behavior of my setup?
What OpenOCD client you're using? I made a mistake using the host gdb and I got this error. And after I modified my debugger path to the location of my arm-none-eabi-gdb in "Debug Configuration" of your eclipse the problem disappeared.
From your post you only mentioned you used arm-none-eabi-gcc toolchain, so don't know if you set your gdb to arm-none-eabi-gdb in "Debug Configurations", which is separate from project toolchain settings.
Another version of OpenOCD helped me. Met a similar issue with OpenOCD 0.10.0 from http://gnuarmeclipse.github.io. Initially it worked then the issue appeared. Removed it and installed the build from http://www.freddiechopin.info.
