UART Debug console for Ivy Plus carrier board

[zjq]

Hello,

I am trying to get the UART debug console for the following setup. I connect the Ivy plus carrier board to my laptop using usb-c to usb-a cable, I was able to use vnc viewer connect to 192.168.11.1 to see the installer and install the Torizon OS. But after I installed the Torizon OS,
I tried to setup the UART debug console, the COM port is not showing up in my windows device manager. I connect the board to my windows 11 laptop using usb-c to usb-a cable. Is there any driver I need to install in my windows laptop to get the COM port show up?
I tried to find the info for how to setup UART debug for Ivy carrier board, but there is no info for the Ivy carrier board. Could you please help with this issue? Thanks!

Hello,

To set up the UART debug console on your Ivy Plus carrier board with a Verdin AM62 module, please follow these steps to ensure proper configuration:

1. Check USB Connection: Verify that the USB-C port on the Ivy Plus carrier board is configured for UART communication. Some USB-C ports may only support power or data transfer without UART capabilities.

2. Driver Installation: Windows should typically recognize the USB-to-UART bridge and install the necessary drivers automatically. If the COM port is not appearing, you may need to manually install drivers. Identify if the Ivy Plus carrier board uses a specific USB-to-UART chip (such as FTDI or Silicon Labs) and download the appropriate drivers from the manufacturer’s website.

3. Device Manager: After connecting the board, open the Device Manager on your Windows laptop and look under “Ports (COM & LPT)”. If the device is recognized, it should appear here as a COM port. If not, try reconnecting the USB cable or using a different USB port on your laptop.

4. Serial Console Parameters: Once the COM port is visible, use a terminal emulator (such as PuTTY or Tera Term) to connect to the serial console. The typical settings for Toradex modules are:

   • Baud rate: 115200
   • Data bits: 8
   • Parity: None
   • Stop bits: 1
   • Flow control: None

If these steps do not resolve the issue, ensure that the USB cable is functioning properly and consider checking the Ivy Plus carrier board documentation for any specific setup instructions related to the UART debug console.

I hope this helps you set up your UART debug console successfully.

Enable UART instead of 'Verdin CAN_1' on Verdin AM62

Hello Toradex Community I’m trying to disable the ‘Verdin CAN_1’ (aka main_mcan0) peripheral which uses the SODIMMs 20 and 22. My goal is to use the SODIMM 20 as UART5_RXD and SODIMM 22 as UART5_TDX instead. im working with the following setup: Verdin AM62 1GB WB IT (V1.1A) Verdin Development Board (V1.1F) TorizonCore Version: 6.5.0+build.8 Host-System Win 10 (WSL2) I’m relatively new to the Device-Tree game and used the the following tutorials/threads as a start: Device Tree Overlays on …

Connecting to Serial USB for Toradex Apalis TK1 Ixora V1.1

Hello, I was given the board already installed with a Toradex operating system, assuming used with Toradex Easy Installer. I would like to replace this OS with one compatible for Qt applications on Linux. How can I replace this OS or put it in a factory reset mode to start over? I tried to connect to the device via serial USB from this post: (I was the one who replied with the other issue installing the APX driver). I can boot into the recovery mode and detect the APX driver but cannot in…

Hello,

From Ivy carrier board data sheet, J1 and J17 are listed as UART connection for Linux Console,
Can I use these for the UART console instead of using usb-c port? What are the pin assignments for those connectors? They are not described in the data sheet.

I got it working, I used J1 for UART console.

Hi @zjq ,

Happy you got to a resolution there. By the way you may have already seen the Quickstart Guide | Toradex Developer Center guide.

Let us know if you have other issues.
By the way you are testing out Torizon OS. Do you already know what OS you intend or think you will use in development and final production?

Best regards,

[zjq]

Michael, thanks for the reply. I did go through quickstart guide, but there is no info for the UART console on Ivy carrier board.

I will use QNX, do you guys have QNX BSP for TI AM62 on ivy carrier board?

[michael.tx]

Hi @zjq ,

You are correct the quickstart doesn’t go into that much detail.

We do not at the moment have a QNX image. I know QNX and us were talking about this at once. Maybe we bring this topic “offline” to study it more.

We will ping you.

Best regards,

QNX BSPs are developed and supported by QNX itself. You can check the list of available BSPs here.

Thanks for the info.
