OMAPL138B-EP: USB CDC enumeration issue

Part Number: OMAPL138B-EP

Hi,

I'm working on emulating a virtual COM port on windows machine using USB. I used OMAPL138 starterware as reference. I successfully added the USB CDC feature on ARM side. A COM port is detected on PC side when the device is powered up. I can communicate with my device using Teraterm software on PC. But this works fine only windows 7 PC. Device is enumerated multiple times(inf file which was provided with starterware project was given to load the driver). There's no issue with enumeration and communication with teraterm in Win 7 host. When i tried it on windows 10 PC, enumeration works fine(same driver file-usbser.sys was already loaded without the need of inf file). But it is not stable as in win 7. Device gets stuck when tested multiple times. Doesn't OMAP starterware project work with windows 10 host?

Regards,

  • Hi,

    Starterware is quite an old release, so it is possible that there are some compatibility issues.
    Can you update to the latest Processor SDK RTOS?

    Does it have USB CDC class example like in starterware? I already started the development based on the startware. It would be helpful if you could figure out the issue with starterware.

    Hi,

    I've notified the RTOS team. They will post their feedback directly here.

    Processor SDK RTOS USB driver only supports USB Audio class and USB MAss storage drivers for this device not USB CDC.

    We have not tested Starterware CDC with Windows 10 since last release for Starterware with this support was made in 2011 which was before windows 10 launch. this code is not under active development and is only available as reference. We currently only support USB drivers available in Processor SDK RTOS for bare-metal /RTOS development and  Linux based drivers for OMAPL138/AM1808.
