2018-09-11 13:55:36 Allie

We have an openCR board in our hands, use the USB data cable to connect to the windows system, how can we identify the COM port? Is there a development tutorial under Windows, and the related usb serial port driver?I use the windows7 system

Hi Allie,


You should look for the "Ports (COM & LPT)" item as shown below.

OpenCR will be displayed as USB Serial Device(COMx)


 

If the Ports (COM & LPT) item is not visible, please make sure that the USB cable supports data transmission.

Some USB cables only support charging batteries.

Thank you.

t is also impossible to identify with the battery power supply, and other boards are used normally.

This is a normal board with the same connection.

Hi,


First of all, please check if micro USB port is damaged.

If it seems not damaged at all, please check correct USB driver is installed with below instruction from eManual

http://emanual.robotis.com/docs/en/parts/controller/opencr10/#install-windows-driver 


Once the driver is correctly installed, OpenCR in DFU mode will be shown as belows.

In order to enter the DFU mode, you have to press BOOT button and then press RESET button.


 

Then try Burn Bootloader from Arduino IDE and see if this fixes the problem.

You have to set as belows


Board: "OpenCR Board"

Upload method: "OpenCR Bootloader"

Programmer: "DFU_UTIL"



 

If above method doesn't fix the problem, please request repair service.

Thank you.
