Virtual Com example problem

hubertmelchert — Tue, 14 Jul 2015 07:40:37 GMT

I'm trying to run virtual com example on TWR70. I'm using IAR and Freescale MQX 3.8. The program seems to run without problems. On my PC i can see unknown USB-SERIAL device. The problem is that no matter which .inf file I try system ignores it. Same thing happens on Win7 and WinXP. What am I doing wrong ?

That helped me to install drivers. Now there is another problem. I can't open serial port that show up in system. While debugging an example i noticed that the program can't go through enumeration process. Any idea why ? I'm using example from MQX 3.8 directory without any changes.

while (TRUE)

{

/* call the periodic task function */

USB_CDC_Periodic_Task();

/*check whether enumeration is complete or not */

if((start_app==TRUE) && (start_transactions==TRUE))

{

Virtual_Com_App(); //Virtual_Com_App() can't be executed because start_app and start_transactions ale FALSE

}

}/* Endwhile */

}
