TS201S EZ-KIT VDK ISR

NathanYoo
on Jun 27, 2013

Hi
           
Is any body is having idea how to can interrupts in VDK for using LinkPort  DMA.
I did test data communication using DMA in the LinkPorts,

referenced by example code "Producer_Consumer_MP" except for Multicore process & message.

when I sarted this code it did not enter the ISR function and driver open funtion.

I don't know What is problem.


with regards,

Nathan

    Hi

    Thank you for your attend to the my linkport problem.

    I am Testing this code on the EZ-KIT

    According to the following Producer_Consumer_MP  example

    case VDK::kIO_Init:     

         ret_val = Init(inUnion);

         break;

    case VDK::kIO_Activate: 

         ret_val = Activate(inUnion);

         break;

    case VDK::kIO_Open:     

         ret_val = Open(inUnion);

         break;

    ...

    and

    int LinkPort::Init (const VDK::DispatchUnion &inUnion)

    {

    // Clear the flag bits

    m_readFlags  = 0;

    m_writeFlags = 0;

    // Create the deviceflags

    m_DevFlagRead  = VDK::CreateDeviceFlag();

    m_DevFlagWrite = VDK::CreateDeviceFlag();

    // Get the link number from the boot I/O object initializer

    m_linkNo = *((long *)inUnion.Init_t.pInitInfo);

    return 0;

    }

    so I think This Part is Initiation of Linkport .

    and procedure of Linport Driver in VDK is VDK::kIO_Init -> VDK::kIO_Open

    Where do i mistake about it?

    If I do not use VDK, I can use Link port in DMA mode. but I want to use LinkPort With VDK Based.

    Where Can i get useful Example Code about VDK?

    Best Regards,

    Nathan
