Hello,
I am trying to understand how to transmit with RapdIO.
I am using a reference design & document from here:
https://www.altera.co.jp/content/dam/altera-www/global/ja_jp/pdfs/literature/an/an568.pdf https://www.altera.com/products/reference-designs/all-reference-designs/interface/ref-serial-rapidio-to-ti-6488-dsp.html I don't understand how to send through RapidIO.
I see in reference code that the sending is done as following :
target_address = (pkt_id & 0x0000ffff) * (payload);
IOWR_32DIRECT(DMA_WRITE_BASE, 4, (int)tx_data);
IOWR_32DIRECT(DMA_WRITE_BASE, 8, (int)target_address);
IOWR_32DIRECT(DMA_WRITE_BASE, 12, payload); // page size length register in dma
IOWR_32DIRECT(DMA_WRITE_BASE, 24, 0x8); // go_bit=1, enable_soft_burst=0, continous mode=0
But I don't understand how these lines code should result in sending data through RapidIO to the other endpoint.
Thank you for any hint.
Ran
