I just got a STM32H747I-DISCO board. When I try to debug it and load the code to it by using its internal ST-Link and STM32Cube IDE. It says :
Break at address "0xa05f0000" with no debug information available, or outside of program code.
And when there comes a little option( View Disassembly) that leads me to some assembly code. How can I fix it? I am just trying to make simple led blinking. To be honest I have no idea how to use this board. This is my first time with it, maybe I am trying to write codes to the wrong core? Or maybe the problem is in the debug properties. I am stuck with it. How can I fix it?
Edit: Okay so I have figured out that it also gives "Program received signal SIGTRAP, Trace/breakpoint trap." error. I believe that is related to GBD but ı don't know how to work with GBD in STM32.
You seem to be making some very trivial error in your code. Since this is led blinking, I am assuming you must have either missed out on some library import or forgot to have provided clock to the I/O ports.
Also, do set up the mode to PULLUP if you are just doing LED blinking.
The above is pure speculation since I haven't seen your code yet.

I am using Unity as a library for SwiftUI quite a while now. However when updating to the newest iOS version (16.1) it stopped working. Compiling runs without a problem but during runtime I get an error when Unity is starting:
in:
I even started a completely new project with Unity included to SwiftUI and get the same error. As this is some kind of assembler code and I certainly do not know how to read it I don't really know where I have to start searching.
In the console I get: "warning: UnityFramework was compiled with optimization - stepping may behave oddly; variables may not be available." I tried several ways to turn off optimization as described in related questions which did not work. When unchecking "Debug" in the scheme options the project starts normally
A similar thing happened to me. I'm not entirely sure if it's the same problem but in the console, I got a message saying UnityFramework is running optimized and may behave oddly. Unfortunately, I've tried a couple of ways to disable optimization but I've yet to find a solution.
For now, I'm able to bypass this error by disabling the debugger entirely. In order to do this, you have to go to Product -> Scheme -> Edit Scheme and uncheck debug executable.
I'm not sure if this will work for you but I figured it'd be worth a shot!
I am using a NUCLEO-G071RB. I implemented this modbus library: LINK. For testing I use ComTest Pro. Everything worked fine in the beginning. Then out of nowhere I started getting issues with 9600 baudrate. Some bytes get cut off and sometimes appear in the next response. This error only appears with 9600 baudrate. Baudrates 2400, 4800, 19200, 38400 and 57600 have worked correctly this far, but I also need to be able to use 9600.
I am new to STM32 and MCUs in general and the fact that errors only appear with 9600 BR is even more confusing to me. When I was using an STM32F446RE, the library worked fine and I didn't have any issues. Same issues appear when using an STM32F030R8.
Has anyone experienced same kind of issues?
EDIT: Out of nowhere it started working again, just like it stopped working. I even tried with project I didn't make any changes to and that works also, even with different RCC and clock configuration settings. Definitely interesting and I am more than sure it will stop working again at some point.
This is my RCC setup:
This is my USART setup:
This is my clock configuration:
I have tried different clock configurations and USART parameters, but haven't found any success so far. I read the reference manual, but didn't get any help from that either.
I don't know if this is allowed here but can someone help me why am I getting this random blue screen? It say's whea uncorrectable error but I don't know which part of my PC is faulty. I noticed the BSOD appears when there is a heavy task like when I am coding in VSCode (running npm install, etc). I will attach here the minidump if someone can read it. If you need more information about my PC, let me know. Please I really need your help. I want to use this PC for programming. Thanks!

This usually happens due to the high temperature in your pc, driver related issues or corrupted hardware. I recommend you try stopping overclocking for some time (if it is) and check if the problem persists. If not, then I think there could be a problem with your hardware itself. Try replacing the motherboard.
I'm a high school student in a class that is using Python 2 on Enthought Canopy Windows Edition. I often get stuck in coding loops, but the only way I can get out is by closing out all forms of open Enthought. Is there any more reliable way to do it? I've been using sys.exit(0), but it doesn't work correctly, and is leaving my coding in a jam. I can't even test it without it getting me stuck. Anyone know how to fix this issue?
If your code is already running, then you can't reliably type a command to stop it, because the prompt won't necessarily be live then.
Often you can use the Run menu's "Interrupt kernel" command, and you should usually be able to use "Restart kernel", though this doesn't work all the time.
I am having some trouble uploading code to my Seeeduino ADK (essentially a Arduino Mega 2560) using Eclipse. Basically, this thread explains my problem. Sometimes I get a series of timeouts using the Arduino IDE upload, which is usually fixed by removing and re-inserting the USB. Unfortunately enough, this does not help fix the problem in Eclipse.
I have been trying to do the upload using AVRdude via the command line (I even tried the "hacky" solution in the last comment of the above thread), but to no avail. This is the line I am using for this:
"%AVR_DUDE%" -pm2560 -cstk500v2 -P\\.\%COMM_PORT% -b115200 -F -V -D - Uflash:w:"%HEX_FILE%":a -C"%AVR_DUDE_CONF%"
Which gives me:
avrdude.exe: stk500v2_ReceiveMessage(): timeout
I know the above batch variables are OK, because AVRdude runs correctly (but then it times out). If anyone has any ideas or tips that could help me with my uploading I would greatly appreciate it. Thanks beforehand.
EDIT: As it turns out, the reason for this may be that the Arduino IDE sends a reset to the board before uploading, something which the Eclipse AVR plugin does not do. I will test this and write a uploading perl script, but I am fairly certain this is the problem.
Your suspicion is correct. The Arduino IDE uses a patched version of AVRDude to pulse the DTR line and reset the board before each upload. For some reason, some people have had difficulty getting the right command line parameters to replicate this on the Mega2560. I've had the same problem myself - ATMega328's work with no problem, but the 2560 needs to be reset manually.
There's some further explanation and tips for possibly getting it working here (check the comments too): http://false.ekta.is/2011/05/avrdude-5-10-arduino-mega-2560-command-line-uploading/
Check out the detail here... http://false.ekta.is/2011/05/avrdude-5-10-arduino-mega-2560-command-line-uploading/
If using avrdude > version 5.1 change the programmer to -cwiring
This will reset the chip first
