Other Parts Discussed in Thread: CCSTUDIO

While we run the usbhosthid project under C:\Texas Instruments\biosusb_01_00_00\packages\ti\biosusb\examples\usbhosthid\
we get the application stall at   dsp_bios_entry(NULL) in HostHidAppMain(void).
 
There is no documents on what this API is doing and what is its dependencies. Please also help us by providing some suggestions
 
Thanks ... Suresh

void HostHidAppMain(void)
{
 int result ;
 printf("USB Host HID Application\n");
  dsp_bios_entry(NULL);   
 /* initialize the hid devmgr application */
 result =  hid_devmgr_app_init();
 if( result )
 {
  /* failed to appinit, uninit the devmgr application */
  hid_devmgr_app_uninit(); 
 }
 while(1);
  
}
Please also find the USB module of the board attached.

    Hi

    Make sure that correct version of all the dependent packages are installed and environment variable set properly. Refer to biousb user guide. Do you mean that control never comes out of dsp_bios_entry() function.  The dsp_bios_entry() is an entry function which further intializes the usb device stack. for more information please refer to usb device stack documentation in /docs folder.

    Regards

    Thanks Ravi,

    The control goes to dsp_bios_entry and never comes out from that. I have used all the packages properly. Please see the list nelow. Please let me know, if I am missing something.

    Thanks ... Suresh

    Hi Suresh,

    I do not see any continuation to your post, have you solved the problem? I am now working with BIOSUSB and I have exactly the same issue. I have an optical mouse connected to the usb port of my board (through a hub) the light that indicates power to the hub and to the mouse are both on. However, In my example the code also never comes out of the dsp_bios_entry? also I couldn't find any reference in the usb_device_stack.pdf.

    Have you solved this?

    Thanks,

    George.
