C6748 USB MSC Device Not Recognised

Brian Boru

Hi,

I am trying to get the usb_dev_msc demo going on my Logic PD OMAP L138 EVM, interested in running only on the C6748 for now. Unfortunately, having successfully compiled and run this demo, my PC will not recognise the EVM as a USB device when I connect my PC to the device (connected to the mini-USB port). I have tried with 3 different PCs running XP, Windows 7 and Windows 10, none recognised the EVM as a USB device. A .INF file is apparently required for the StarterWare CDC demo, but not for the MSC device demo. I am running the demo from CCSv6.1.1.00022 using an XDS510 Plus emulator. I have searched the forum, but haven't found anything on this particular use-case.  I've seen that some people had similar issues with early StarterWare releases, but even those issues apparently did not apply to running the demos from CCS. e2e.ti.com/.../627819

Any suggestions anyone?

Thanks

Brian

    Dear Brian,
    Please make sure that you are running EVM based example code not LCDK.

    Hi Brian,

    I have personally ran this starterware example, ( i.e., USB MSC device example. ) many times on C6748 LCDK board successfully using CCS.

    First of all ,
    1. please make sure that the jumper ( J2 ) is removed on C6748 LCDK board. For enabling the USB peripheral mode of C6748, this jumper settings needs to be removed. For C6748 to act as USB host mode, jumper should be attached.

    2. Then import, build and run the example, USB_dev_msc on target connecting to a PC on which the CCS run and the emulator is connected.
    Make sure the program runs on the target by getting the output messages on the UART.

    3. Now, connect the EVM to another Windows machine or Linux machine.

    4. Observe that the EVM will get detected on the Windows machine or Linux machine as a pen drive ( Mass storage device ).


    Follow these steps, If faced any problem, please revert with the screenshot on the particular step you failed......

    Good luck,
