USB CDC on FRDM-K66F board

Mbed OS
1

Hi. I am trying simple USB CDC example
https://os.mbed.com/docs/mbed-os/v6.2/apis/usbcdc.html
however I receive “This board does not have a hardware USB driver” error.

How can I fix (or properly configure) it.
Thank you,
Igor

HI Igor,

if you look at mbed-os/targets.json at master · ARMmbed/mbed-os · GitHub you can see that the K64F has USBDEVICE in the ‘device_has_add’ section but the K66F does not, so this would imply that the K66F has not had the USBDEVICE enabled for it yet.

Anna

Hi Anna:
I have a FRDM-K64F board and I want to use the example in the following link:

USBCDC - API references and tutorials | Mbed OS 6 Documentation

A serial port is generated on my PC but I do not receive data, according to the code:

      char msg[] = "Hello world\r\n";
     cdc.send((uint8_t *)msg, strlen(msg));

Could you help me?
Greetings
Carlos
