You can create your logic to detect when the wireless frame is received, and then use the rxm_irq_i signal to trigger the interrupt. It should work.

Hi SK,

Our engineer checks our FPGA design, and found we use AVMM-DMA, instead of AVMM actually.

They said there's no " rxm_irq_i " pin line under AVMM-DMA mode. Is this correct ? AND if so, how to trigger the interupt undr AVMM-DMA on A10 pcie ?

Thanks for help.
