RNDIS Support in MQX 4.1.0 for K70 Board

We want to enable RNDIS support on MQX. 4.1.0 .In short, we need to get “OS\usb\device\examples\cdc\virtual_nic” running successfully.


As per Freescale documentation we are using RTCS module to achieve RNDIS.

We have enabled following in user_config.h:

#define RTCSCFG_ENABLE_ICMP      1

#define RTCSCFG_ENABLE_UDP       1

#define RTCSCFG_ENABLE_TCP       1



#define FTPDCFG_USES_MFS         1

#define RTCSCFG_ENABLE_SNMP      1


While compiling the usb_device code (after enabling the macro DELAYED_PROCESSING), we are getting some compilation errors.

The same compilation issue is discussed in Freescale Community too , but no solution offered.


  1. How do we successfully compile the usb cdc device component for RNDIS ?
  2. What additional changes to do done to execute “virtual_nic” ?
  3. How to test if the RNDIS is working ?
