I'm currently trying to set up CLion for embedded development. Running 'build' by itself creates the executable without any issues, but trying to start the debugger fails with the following error:

If you don't have a hardware reset line available, try changing your openOCD configuration to include:

I have the stm32 nucleo board wb55rg and am trying to flash some examples into it like blinky and a custom sample, but when am trying to flash the project into the board after building it, I am getting the same error (timed out while waiting for target halded) and I dont know how to deal with it. I was searching on internet and I found some info's about OCD and I didn't really understand. I am not using STMCubeIDE only zephyr's sample blinky. Can anyone help me with that ? I am using linux OS from VM box and a simple blinky sample from zephyr.

Answered 2021-Aug-11 at 21:04I have found the problem of this issue. This board was used its previous owner has changed some togle pins on the board. So I searched for the default pins of stm32wb55rg and when I set the default pins the error was solved. Thanks a lot everyone who has made a reply to this post in order to help me find out what was going on.
QUESTION
I am debugging board STM32f4 Discovery on Ubuntu 20.04 with openocd and arm-none-eabi-none. Things work well until yesterday. Today, when I connect the gdb to localhost:4444, following assertion happened and ocd quit:
...ANSWER
Answered 2021-Apr-26 at 01:45I found the issue: I scale up the clock speed without switching to appropriate Flash Latency so the debugger will lose the track of program address as mentioned here, in Clocks and initial settings part: https://vjordan.info/log/fpga/first-steps-with-the-stm32f4.html

I am maker a currently playign kinda thing but the problem is im trying to update the currently playing song every few seconds but it keeps saying '(1400, 'GetClassName', 'Invalid window handle.')' whenever it updates
...ANSWER
Answered 2021-Apr-22 at 16:16SwSpotify isn't catching exceptions when it uses win32gui.enumWindows. You can add your own exception handling around the calls.
You can also use spotify.current() to get both the song and artist at once.
I also don't see any reason for getting the song and artist before the loop, since the loop overwrites them immediately.
QUESTION
I have an real-time OO program (nevertheless written in C) that I am trying to debug. I have an issue that some objects out of thousands get corrupted during a specific window of time, every now and then. I want to have one breakpoint at the start of the window, which automatically sets a watchpoint on a member variable, and then have that watchpoint removed at the end of the window by another breakpoint. The trouble is I need some way of tying a watchpoint number to a given object. If I could construct a convenience variable by some mechanism so that, for example, if $var=28, then set $x${var}=watch -l foo would be the equivalent of set $x28=watch -l foo. (which doesn't actually work) This would allow me to do this:
ANSWER
Answered 2021-Apr-21 at 14:39You can use GDB's eval command to set and use variables whose names are composed of the results of numeric or string expressions.
You can think of eval as doing a printf of its arguments and then executing the resulting string. eval "set var $x%d = 1", 5 will run the command set var $x5 = 1.
The other piece of info you need is that the watch command, as with all breakpoint commands, will set the convenience variable $bpnum to the breakpoint number.
QUESTION
Looking at this code:
...ANSWER
Answered 2021-Feb-07 at 15:12The explanation is very simple.
a && a++ is a logical operation and its result can be 0 or 1. As a is non zero and any non zero value is considered as the true the result of this operation is 1.
This value is added to 252. The result displayed is 253.
QUESTION
My intent is to be able to catch when a global variable has some exact value. GDB has data watchpoints according to which this can be implemented.
Consider this simple program written for x86 Linux:

Answered 2020-Jun-03 at 15:29None of the software I know does it out of the box. When |I use the DWT usually I set it in my software. I have not found any way to program it via any variant of gdb (except manual setting the registers - but it is too annoying)

Install watchpoints
You can use watchpoints like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
