    Hi,

     

    Have you connected two USB cables to PC? One is for emulator and the other is actual USB application.

    Regards,

    Hyun

    Hi Hyun,

    thanks for reply, I haven't connected two USB cable !!

    I have connected my board device TMS320C5505 eZdsp USB Stick directly to USB port of the PC's motherboard (this is emulator or USB application?)

    What is other USB connection?

    Thanks

    Patrik

    Hi,

    That is for emulator. USB application uses mini-USB connector.

    Regards,

    Hi Hyun,

    thanks for answer, now it's all ok, can I ask you an other question please?

    I try to run example CSL_USB_IsoFullSpeedExample_eZdsp_Out from C55 Connected Audio Framework EZDSP 01.51.00.03,

    I don't receive errors or warnings, but however in some lines code of files *.c (i.e. csl_usb_iso_fullspeed_example.c, code_aic3254.c,...)

    is indicated "sintax error" (without other information).

     

    Example of this lines are:

    *(volatile ioport unsigned int *)(0x7004) |= 0x0001;

     CSL_FINS((*GPIO_DOUT0_ADDR), GPIO_DOUT0, 0x0000); /* reset active low */

      pReg = (volatile ioport Uint16 *)EMIF_SDTIMR2;

    I was observing that it seems a problem about ioport, what can i do?

     

    Resume my configuration:

    CCS :5.1.0.08020

    Device :TMS320C5505 eZdsp USB Stick Rev C

    DSP/BIOS :5.41.11.36

    Code Generator :TI v.4.3.9
