Hi Everyone

     Now I  use RT1064-EVK to test the project usb_device_cdc_vcom. I use CMSIS DAP which is placed on board and I connect a USB cable between the PC host and the USB device port on the board. But the project usb_device_cdc_vcom can't  work normally. Can you give me some advice on how to use this project?

Hi  Chris Song,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
To provide the fastest possible support, I'd highly recommend you refer to the readme.pdf to learn how to get start with the usb_device_cdc_vcom.

Looking forward to your reply.

Have a great day,

Hi  Chris Song,

Thanks for your reply.
According to the readme file, I just tested with the MIMXRT1064 board on my site, the usb_device_cdc_vcom can work well just as the below figures show.

Hi  Chris Song,

Thanks for your reply.
After plugging the USB port J9, if the usb_device_cdc_vcom demo works well, it means that the enumeration successful, then a new terminal port will exist, open the port in a terminal tool, such as PuTTY.

Hi Jeremy

     Thanks for your reply. Now I use Putty as a terminal tool to open the port.But I don't understand how to send string "ddabdcdd" that you provided in the second picture. You use terminal v1.9b to send  the string "ddabdcdd" and the string display on Putty?

     Thanks.

Hi  Chris Song,

Thank for your reply.
1) You use terminal v1.9b to send the string "ddabdcdd" and the string display on Putty?
-- Yes, after the USB device enumerates successfully, using the Putty to open the virtual com port and the USB device would echo the printed character.
