I have fresh STM32 L1 discovery board, and it seems to be broken.
But I am not completely sure.
When connecting board via USB to the Linux machine, board starts
perfectly fine, and the demo works just as described by vendor.
But I am unable to actually connect to this board.
➜ lsusb -s 002:074
Bus 002 Device 074: ID 0483:3748 STMicroelectronics ST-LINK/V2
Board seems to be connected, big jumper (CN3) to switch between ST-LINK and DISCOVERY is set to DISCOVERY. But when I try to use st-link utility
I am receiving.

The chip on board is STM32L152RCT6. I worked with STM32F0..4 before and had never such problems, but I did not worked with L series before, so I am not sure if this is board problem or I am skipping something important here.
EDIT: Using OpenOCD i found out not expected behaviour. At first run I am receiving error:
Error: init mode failed (unable to connect to the target)
At second run:
Error: reset device failed
Then device dissapears from the system, dmesg leaves messages:

I think there might be a problem with adapter speed, but I am not sure for now.
EDIT2: I tried with Windows ST Link Utility and I am not able to connect to the board, board causing "Detection Error" or "Connection Error", software suggests changing SWD frequency or mode. I tired with literally every combination but none works.
EDIT3: If this helps somebody, board was sent back, I have got information that it is actually broken and I have got new one. New one works flawlessly as expected.
Sometimes I work with the same L1 Discovery board on GNU/Linux. Both texane/stlink and OpenOCD detect it flawlessly without any modification. You can see the outputs:

Maybe your board is really broken but before recycle it I suggest you two different trials. (a) I think after your question you have another ST (as you mentioned STM32F0..4) board perhaps with ST-LINK adaptor. You can use it as an external ST-LINK (follow eg. this). (b) Try to upgrade your embedded ST-LINK firmware with the STSW-LINK005 which java version works also in GNU/Linux environment. The board performs well for me both before and after upgrade.

On one of my raspberry pis (Raspbian OS) with a USB serial device connected, there is periodic disconnection of the serial device while still being registered as a USB device.
lsusb returns a valid Bus Device entry, but there is no corresponding /dev/serial/ entry.
The only way to fix this issue is rebooting the pi, which I'd like to avoid.
I'd love some ideas on how I can debug USB serial connections on a Raspberry Pi Linux platform, or methods to reset the serial connection without requiring a reboot.
We tried:
Tracking udevadm monitor to see USB related events. This is what is seen where we catch a serial disconnection / reconnection happening:

Checking if the raspberry pi was overheating, using vcgencmd. It returns 8000 Soft temperature limit has occurred flag sometimes, but not always.
Tried the following method to "reset" the serial connection, which had no effect
echo -n '1-1.3:1.0' | sudo tee -a unbind
echo -n '1-1.3:1.0' | sudo tee -a bind
Followed some of the solutions here: https://raspberrypi.stackexchange.com/questions/9264/how-do-i-reset-a-usb-device-using-a-script, including the solution to reset the USB bus, with no luck.
USB Serial malfunctioning may be caused by many different factors, including software, hardware or noisy environment.
The following diagram roughly describes the related components,
-------------------- ----------------
| Userspace (Apps) | | Power Supply |
-------------------- ----------------
^

-------------------- ------------- ----------
| Kernel (Drivers) | <-- | USB Cable | <-- | Device |
-------------------- ------------- ----------
Narrow down to the faulty part
As first step, elimination method can help us to narrow down to the faulty part, basically you replace the suspect part with another good component, and observe if it changes result. for example,
use the latest official raspbian image to eliminate userspace issue
choose a different kernel/firmware image to eliminate kernel/driver issue
change usb cable
change usb device
use a decent power supply
Troubleshooting on software issue
Assume we could narrow down the scope to software, I would use the following procedures to do further check,
Make sure the usb device is recognized by kernel, check with lsusb, dmsg, udevadm.
Have a correct name (dev path), check udev rules;
Run udevadm monitor to observe any unexpected disconnection events, make sure it works (stable connection) on a fresh OS image, and install only necessary packages step by step.
Other tips
Check if your usb device is a "smart" device? meaning the device may have its own logic to disconnect or change mode, so that affect your host side connection.
To see what happened on the USB bus it is better to use usbmon (see https://wiki.wireshark.org/CaptureSetup/USB).
I think you should carefully check usb descriptors: lsusb -v and check how much current it attempts to take (check configuration descriptor: https://learn.microsoft.com/en-us/windows-hardware/drivers/usbcon/usb-configuration-descriptors).
I think reconnects could occur due to insufficient current to you usb device especially if device supplied only from bus. If current > than usb host controller can provide, usb host-controller limits current this could lead to device reset. To check this hypothesis connect your device to Raspberry using active hub with external power supply.
I have a problem with flashing proc using https://github.com/stlink-org.
Using windows STM32-Utility all works fine on every programer.
I also using debug which works correctly
Tried on other version v1.6.1.8x or 1.5.1 - this same problem
My setup:
Raspbbery Pi 4 with NOOBs
STM32F723, also i tried on Nucleo programer and ST-LINK / V2
stlink version - v1.6.1-201-g4bfaab0
At this moment I can erase memory, but that's all. When I tried to flash it crashes.

I have a Segger J-Link which I am trying to use on a Macbook running MacOS Catalina 10.15.4, with openocd and GDB against an ESP32 board. The problem is that I can not seen the device:
$ ls /dev/cu.*
/dev/cu.Bluetooth-Incoming-Port /dev/cu.JimsiPhone-WirelessiAP /dev/cu.SLAB_USBtoUART /dev/cu.usbserial-0001
None of these is the J-Link. If I run lsusb I can see it:
$ lsusb
Bus 020 Device 002: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 020 Device 003: ID 1366:0101 SEGGER J-Link ARM
I have installed the "J-Link Software and Documentation Pack" downloaded from Segger. I have checked the Mac "Security and privacy" settings and it does not report that it blocked any drivers or programs from being installed or run.
On the J-Link, the green LED is on, with a very brief flash about twice per second.
I'm sure I have a piece missing, and would appreciate some help.
UPDATE: I have been following instructions here:
OpenOCD Instructions
It all works until I get to step 6, and I follow these instructions:
Serial driver instructions
The problem is, a path for the driver never shows up, as I described above. I don't think I can run OpenOCD if I can't make it talk to my J-link.
When I run openocd-esp32, I get (full paste from openocd-esp32 output is below):
Error: No J-Link device found.
The contents of esp32-wroom-32.cfg is:

After doing the above I now get a different error message when running openocd-esp32 (perhaps because of the J-Link FW upgrade?). Initially it complained that there was not an adapter speed set, so I modified interface/jlink.cfg and added:
adapter_khz 3000
I now get a different error:
Error: JTAG scan chain interrogation failed: all ones
Which I have been Googling, and which could mean a bad board or still another configuration issue. There is no SD card in the SD card socket and no other SPI devices on the board, although the ESP32-WROVER-32U has SPI flash on it.

Success! This circuit used the Segger 10 pin needle connector. On that connector pin 1 is VTREF and on my board it was left floating, when it should have been connected to V3.3. I connected it and:

I would suggest to validate your setup step by step - I personally do not like big bang integrations.
Verify that your the Segger software can see your JLink probe - the good thing is that lsusb can see it. JLink Commander should provide some useful information.
Launch openocd without any executable-related arguments: openocd -f interface/jlink.cfg -f board/esp-wroom-32.cfg
Verify that basic commands are working, i.e. resetting the CPU, displaying registers, reading/writing memory.
If you you are still experimenting issues, double-check your wiring - see here for more information.
I am running a RaspberryPi with raspbian-wheezy:
uname -a
Linux raspberrypi 3.18.5+ #744 PREEMPT Fri Jan 30 18:19:07 GMT 2015 armv6l GNU/Linux
How i want to use a NetGear N150 Wireless USB stick as a wlan interface:
dmesg
[ 3.401856] usb 1-1.2: new high-speed USB device number 4 using dwc_otg
[ 3.523552] usb 1-1.2: New USB device found, idVendor=0846, idProduct=9043

[ 3.547744] usb 1-1.2: Manufacturer: Realtek
[ 3.553858] usb 1-1.2: SerialNumber: 00e04c000001
The device is not automatically detected. After plugging in the stick into a windows machine, it seems as the stick uses a Realtek rtl8192cu chip. Loading the 8192cu kernel module does not seem to work, there is still no wlan0 device.
Any ideas?
Never mind, I found a solution:
The usb id is not detected by the 8192cu kernel module as a supported device. After tweaking a bit and adding the following code to the rc.local file, everything works as expected:
modprobe 8192cu
echo "0846 9043" > /sys/bus/usb/drivers/rtl8192cu/new_id
ifdown wlan0
ifup wlan0
To have this handled automatically on module insertion, put the following line in /etc/modprobe.d/netgear_n150.conf:
install 8192cu /sbin/modprobe --ignore-install 8192cu; echo "0846 9043" > /sys/bus/usb/drivers/rtl8192cu/new_id
Going the extra mile: having it load automatically is more system specific, but on Arch Linux, adding a file in /etc/modules.load.d containing the module name is sufficient.
I am trying to debug a sample code given by Atmel. I have built the program successfully.
For debugging, I am using eclipse plusgdb plus JlinkGDBServer plus onboard Jtag.
Although the program can be downloaded to the board and is running well, I can't debug the program. Everytime I launch a debug session, the JLinkGDBServer will be terminated with an error as below:
Below are the messages shown in the console for each program termination:

The following is my debugging configuration:

target remote localhost:2331
monitor reset
load
mon reg pc = 0x300000
mon reg pc = 0x300000

I dont know what root cause is. I suspect that it is arm-none-eabi-gdb that causes the JLinkGDBServer to terminate with an exit code of -1.
Please help.
Edit 1
FYI, I am using SAMA5D3x-EK development board.
It is difficult to say, but looks like if the processor is having an exception while loading your code. I suggest to verify the load address of the sections of your ELF file, and review the linker settings of your project.
Hope it helps...
