If you are sure you have access rights and no microcontroller attached it is the normal behaviour you don't get any output. This is currently a limitation of how probe is implemented, you must attach a microcontroller to show detailed information. I have written an experimental project to solve this limitation and probe attached programmers even in the case when no mcu is attached. See: https://github.com/xor-gate/stlink2. I didn't put much effort in the problem to port it back into the texane/stlink project (yet), as it is not as easy as it looks. Still your issue is valid and should be fixed for convience.

OK, thank You for the info but the correct output with data is given on my older image of RPI also with no target attached to programmer(stlink V2 copy). So I assumed I have missed some settings (I am not sure about access rights if everything is OK). I will try your solution also. And I have target attached.

EDIT:

Your tool is working. Thank You

So to summarize, you dont run stlink/stlink2 as root and stlink2 show the expected output with serial of the programmer (and when attached the chipid)?

@xor-gate
same problem.

not available.

same problem
on a Gentoo Linux machine
Yesterday the atollicTrueStudio told me that the STLink firmeware on my STM32F411 Nucleo is old and there is an update available
-> OK

then i debugged a part of software ...all works for about 2houres
OK then i disconnected the board,
powered off my PC and today it doesn't work any more
the Program on the Target is still running like charm
BUT
there is no more connection

dmesg

so it looks like Atollic has, with this update, killed the STLink on my nucleo device :cry: :oops: :evil:

perhaps somebody knows how to fix this problem

Same problem with rebooting MacBook.

@lkord @artbody @RockyF: What st-link version are we talking of? We need more details here on build environments and hardware.

XNUCLEO-F103RB here, and the same symptoms. Firmware upgrade and now chip id shows 0000 for the thing.

@ all: Please make sure you report all your software and hardware info:

• Operating System
• stlink-tools Release
• Programmer Type + Firmware

Debian Unstable
Package: stlink-tools
Version: 1.6.0+ds-1
I think this is st-link/v2 programmer, it was bundled with the xnucleo board. I am extremely new to this =). Maybe this is relevant:

[637361.699535] usb 1-1: new full-speed USB device number 56 using xhci_hcd
[637361.848669] usb 1-1: New USB device found, idVendor=0483, idProduct=3748, bcdDevice= 1.00
[637361.848670] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[637361.848671] usb 1-1: Product: STM32 STLink

[637361.848672] usb 1-1: SerialNumber: QÿkxfVS34g

For anybody else possibly googling this. I happened to have a copy of the original board firmware ad a .bin file and managed to get it back working by putting a jumper on CN7 pins 5-7 and then running st-flash writing the original firmware to the board.

@jpesonen-priv: ok, good, but that still does not give any idea on why this happened (which is the relevant point to us)...

@Nightwalker-87 I can reproduce this too by flashing anything with the STM32CubeIDE to the board, but I don't know what is and how to get information relevant to you.

As it reads, @lkord was able to rule out that the st-link tools were source of this problem.

The findings of @artbody, @RockyF and @jpesonen-priv seem to be a different problem.
Here it looks like as if a corrupted firmware image has been loaded to the programmer, what resulted in the same output on st-info --probe. This appears to be not related to the stlink-tools, so that we can't provide any support here, apart from suggesting to look for a newer genuine firmware revision for the used programmer and to verify a downloaded firmware-file by a checksum. If no newer firmware is available, one would have to reload the original one, as explained above.

Thx for the helpful feedback @jpesonen-priv which now allows to close this ticket with a solution. :+1:
