SK-TDA4VM: SK-TDA4VM

Part Number: SK-TDA4VM

Tool/software:

Is ther any detailed information available for setting up the CLEC event controller to trigger an interrupt on the C71x in response to a PCIE MSI interrupt previously setup by Linux running in the A72 cores.

There is some limited information regarding the CLEC interface to the GIC-500 interrupt controller provided in the TRM. There are no examples in the Linux SDK or FreeRTOS PDK that can be used as

a reference to the CLEC interface.

Thanks!

    Hello,

    I am unaware of any example code which is direct linking PCIE events to the C7x core through the CLEC.   The PCIe SW reference's today are A72 HLOS centric (Linux, QNX).  If your need is to work in the large existing stacks, it might be most straight forward to use the existing Linux features to pull the data in, then signal the C7 to process the buffer.  Direct linking the C7x would take some research and per-stack surgery and it might not end up working out if the there is some resource conflict.

    Regards,
