I have tried to connect on a trace32 Lauterbach debugger via ethernet but I can't made it work. I can only connect via USB. I followed the steps from lauterbach website but a I can't check "full duplex" option. Could that be the problem?
This is the problem I get:

I'm attempting to connect to a Cisco 4010 network switch via it's built in usb port (which internally is a usb to rs232 adapter wired to the back of the console port).
I have installed the Cisco usb console drivers version 3.1
When I plug into the usb port, the little green LED that indicates that the console port has switched to usb does not light up.
When I run putty, and attempt to connect via serial connection to COM16 (the usb to rs232 in the cisco switch) I get:
Unable to open connection to COM16
Opening '\.\COM16': Error 1450: Insufficient System resources exist to complete the requested service.
I have tried reinstalling the drivers to no effect.
I have 3 identical switches, which give me identical behaviour, all 3 new out of the box with no programming.
Changing the Baud rate makes no difference, not that I'm expecting it to as the issue seems to be COM16 doesn't exist or similar
Putty Settings and Device Manager
With the help of a colleague, we narrowed the issue down to windows using a default usb to rs232 driver rather than the cisco one I had installed. The big clue came when I tried using putty inside a VM and it worked, while on the host OS I was still getting error 1450.
We had to compeletely uninstall all drivers, reboot, reinstall drivers manually, reboot, then attempt the usb connection again.
The last comment here describes it:

I will copy the solution across to here, for easier search of the solution for the next person who has the same issue.
For WIn10 , install the setup(x64).exe from the Cisco_usbconsole_driver_3_1.zip.
Check that the Cisco Serial (Comx) is using the correct driver provider which should be Cisco. Don't use the Cypress driver.
Device Manager
To update the driver,
If you installed it already and having issues, uninstall it using the setup(x64),exe then reboot PC.
Uninstall Cisco Driver
First, disconnect the blue Cisco USB console cable. Reinstall the Cisco USB console drive using setup(x64).exe from the Windows_64 folder which was extracted from file Cisco_usbconsole_driver_3_1.zip.
Reboot PC
Open device manager to observe the driver installation. Check that you see "Cisco USB to Serial Adapter". If you don't see it repeat the above steps.
if you see above "Cisco USB to Serial Adapter". then
Update Driver
Click UPDATE DRIVER, then Browse my computer for driver software.
Choose " Let me pick from a list of available driers on my Computer." Select "Cisco Serial".
Pick driver
Finally,. connect to the COM port x indicated in the Device Manager, Ports (COM & LPT) , Cisco Serial (COMx)
I can open my ESP32 Vroom32 device made by Espressif with a cp2101 chip on Ubuntu. I used Ubuntu to flash Micropython onto it, however when I try to connect with Putty, MPFshell or anything else on Windows 10 it will not work. I downloaded and installed the recommended drivers for it and also updated Windows which was supposed to load the driver as well. I can see the device and COM port in device manager but when I attempt to connect I get blocked. For example on MPFshell I get the message "Cannot connect to COM17"
It is a common reason for boards to show the "Cannot Connect to COM" error because of a bad USB cable.
Always check with another cable first, before getting deeper to the problem.
I'm working on STM32H7 evaluation boards (Nucleo-144 and EVAL2). My IDE is STM32CUbeIDE.
My goal is to debug remotely: run STM32CubeIDE (or another IDE) on a Linux server and connect to the board through the network.
I could run successfully the following setup:
connect the board to a local PC
launch GDBserver on this local PC
on the distant Linux server, setup the Debug Configuration to connect to the remote GDB server.
This is working fine. But I need to go further: I'd like to remove the local PC, ie. the board would be connected directly through ethernet to the network.
I've been told that there is a JTAG/Ethernet adapter for Xilinx, called Smartlynq that allows to do that, but the way it works is a bit confusing for me.
Do you know about an equivalent for STM32 ecosystem ?
Would there be another setup to debug remotely without a PC in between ?
The Segger J-Link PRO is a JTAG/SWD debugger for ARM that supports Ethernet. Like the other J-Link models, it should work fine for STM32.
Use a Raspberry PI as a debug adapter.
It would be somewhat cheaper than a JLINK Pro. If there is WLAN available, take a Pi Zero W, otherwise you'd need one of the bigger ones with Ethernet. Set it up for remote work (enable ssh, set a fixed IP address etc), then you can disable the GUI desktop, and disconnect the display and the keyboard.
Running gdbserver
The Pi has an ARM CPU which supports the Thumb instruction set but not Thumb-2, so its native gdbserver might be able to debug a Cortex-M7 controller. If it can't, then you have to install the gdb-arm-none-eabi package on the Pi.
Connectint to the target board
There are two alternatives.
Connect the onboard debug adapter to an USB port on the PI, and run openocd just the way you do it on a PC.
Bypass the onboard debug adapter, and connect some pins on the Pi directly to the SWD pins of the target. You have to remove some jumpers to disable the onboard debug adapters. There is a tutorial at Adafruit on how to compile and use openocd with native SWD support.
I'm fighting strongly against a problem that is making me crazy.
I’m extensively using QEMU over a Win7 64bits machine for running different Linux VMs (Debian, Raspbian).
In the past I configured the network following the QEMU instructions using the OpenVPN TAP device and network bridge in Win7 : it ran perfectly and the Linux machine was able to connect the “real world” networks, internet and so on.
In the last few days, on the contrary, this nice behavior stops working. The Windows situation is unmodified (the OpenVPN TAP driver settings are the same, the bridge is still there, when the bridge is active Windows still see the network, the TAP driver becomes “busy” when the QEMU VM starts as usual, the QEMU startup scripts are still the same…), but the emulated Linux system (whatever image I use) is unable to connect the network.
The “eth0” interface is active but unable to get the IP address from the DHCP and also using fixed IP address doesn’t solve the problem, since the IP address is not seen by the “real” network.
I have tried to uninstall and reinstall again the OpenVPN TAP driver, to downgrade Win QEMU to the previous version, but no way !
The only change that I made in the HOST configuration has been to install GNS3 (with its own TAP driver), but without including the QEMU VM in any GNS3 network.
Does anybody have suggestions regarding what kind of checks I have to do on QEMU in order to solve the problem ?
Any help will be appreciated

I was finally able to get out.
I was forced to restore a previous system image : all attempts to uninstall and reinstall the OpenVPN TAP driver were useless.
The problem is probably due to the update of the OpenVPN TAP driver : with the v.9.0.0.9 no problem, but updating to the 9.21.1 seems to have generated the problem.
I'm now able to use again QEMU and GNS3 in network.
But what a strange case !
I am trying to write an application for myself to learn things and to use in my own office. What I am trying to write is:
I have two nics. First one is connected to internet and the other one is connected to network
I have enabled ICS (Internet Connection Sharing) in my own PC
Other computers (Laptops, iPads etc.) are connecting to internet using my PC
So my c works like a hotspot
I am trying to see where they are connecting to and log their IP and MAC address. If I can do this, I will also add sign-in function at future.
Actually, my LSP supports TCP, UDP and RAW protocols. It works both on x86 and x64 Windows OS (Tested on Windows 7). However, when I connect to internet through this PC using my iPad, it doesn't seem working. WSPStartup never called.
If you have any idea, I will be more than happy.
Bests,
You need to use NDIS, a library like WinPCAP would do the work.
