EVMK2H: Need an QMSS example of using external linking RAM

Byoung Kil Song

Part Number: EVMK2H

The application that i'm trying to make requires more than 32K descriptors.

Will you provide example code for BIOS/ARM core which utilizes external linking RAM? Or please give me an instruction where to change in the existing example.

And, please let me know any side effects about using external linking RAM.

Thanks.

    It seems I didn't provide enough information..., let me try explain the problem again.

    QMSS has internal link RAM, and it provide maximum 32K entries. Therefore you can manage maximum 32K descriptors with this link RAM.

    The problem is that it's not enough number for me...so I'm trying to find a way to raise the number of descriptors.

    It seems like link RAM can cover more than 32K entries if it is located outside of QMSS - external memory.

    I need an example code that utilizes external memory as link RAM, and please let me know differences according to location of link RAM - such as performance degradation, etc.

    Thanks.
