I did a program using ST-Link debugger on a custom board. The program is working fine. However, when I program the chip using ST-Link utility, the program is not starting without the ST-Link connected. When the ST-Link is connected, the system starts.
Anyone had such an issue?
Ok it is a bit stupid but I have to admit that in the stress I got a bit blind.
When I said:
The program is working fine however when I program the chip using ST-Link utility, the program is not starting without the ST-Link connected.
I was actually testing with only the usb removed from the ST-LINK and not removing totally the JTAG. So now I know that the ST-LINK is pulling down the reset when not powered.
Thanks Tom and staringlizard, you noted interesting thinks. Actually the Boot0 was my previous issue...

I am attempting to program a STM32VLDiscovery Board, using Visual Studio 2019, Visual GDB and STM32CubeMX. When I connect the board to the machine, it appears as 'USB Mass Storage Device'. I am using a Windows 10 VM. The program builds fine, but when I attempt to begin on-board debugging, I get an error message stating:
USB Mass Storage Device" does not appear to have "ST-Link Driver"
driver installed. The debugger may have problems finding your decvice.
Try installing it now?
If I click yes, then a bit of software called UsbDriverTool.exe starts and a progress bar appears with the message
VisualGDB is installing the following USB driver: ST-Link Driver the following device: USB Mass Storage Device
This then fails with the message
Automatic driver installation gailed. Do you want to try installing it manually?
Clicking 'yes' again gets the message
USB driver installation failed with code -532462766
And then finally
open failed (no matching adapter found)
Can anyone tell me please, how I go about getting the ST-Link driver on to the discovery board so that I can start debugging my code?
(One other thing that may be relevant. I tried using the STM32 ST-Link Utility program to program the code on to the board. I find that it will only connect to the board if I am holding reset whilst I press the 'connect' button.
I'm trying to emulate STM32F429I discovery board using qemu & eclipse IDE. I got the blinky example running with the led turning on and off on the graphics screen but I have tried an example to run the on-board screen and it doesn't seem to be running, Is it supported? Also, many drivers fail when simulated with qemu (sdram, rcc, ...) How can I know exactly what peripherals that are fully supported?
Here's the part of documentation about the board, What is meant by "FP not emulated" anyway?
I'am using IAR Workbench and I am having hard time to flash my STM32F407VG I got:
FATAL error ST-Link No MCU device found.
The USB cable connecting the laptop and the MCU is new so I don't think it's the problem.
ST-Link en.stsw-link009 is installed
When I go to project options Debugger > ST-Link > Reset > connect during reset and try to download again I got:
Warning stack pointer is setup to incorrect alignement stack addr = 0x00000016 after the download progress bar stay blocked.
By navigating in the option menu I find it's possible to adjust CPU frequency actually it's 72 MHz, the default one, I changed it to 168 MHz, the CPU frequency but the problem remains.
Could you please suggest me some solutions to debug/resolve the problem.
Edit
I have used STM32 ST-Link Utility and i succeded to connect to the board, But the problem with my IDE is not resolved yet.
I used ST-Link Utility to erase flash memory, once this is done i activated
Debugger > ST-Link > Reset > connect during reset
and all works well, i don't know why but i'am glad to see my board works again
Thank you for your help
I am currently running a VB application through mono on Raspbian. After a bit of troubleshooting the program boots and appears to be running quite well. However if left to itself for a few minutes the VB application just shuts off. This program runs excellently on the windows pc for any duration. Barring this being an issue with the VB code itself is there any major PI related issues that I may have missed in setting up mono? I set up mono the usual way and am launching via "sudo mono app.exe" in terminal.
Thank you for any insight you may provide into this!
UPDATE: mono just FINALLY threw out an errot to me System.OutOfMemoryException : Not enough memory to complete operation [GDI+ status: out of memory]
UPDATE2: Memory leak, its a code related issue.
Hi to anyone else that runs into this issue. For us it was a memory leak.
I trying to write a small c program witch reads out an GPIO pin to shutdown the pi externally. The triggering of the signal is working well. The program is started by LXDE as autostart application. If the program detects the shutdown signal it's performing:
sync();
system("halt");
Why does this program damage my ext4 file system after a couple of reboots. There is no fixed number of reboots necessary to damage the system. I don't see any difference by writing halt to command line. I'm using the newest version of the firmware(last update today) and also the kernel is up to date(last update today).
Does anybody have an good idea about it?
This app is a good idea, i wonder nothing like this is already existing...
I think the problem is the "halt" command.
You shuold use the explicit command "shutdown -h now" instead.
