Hello,

From: paragon [mailto:commoon@wins21.com]

Present, not trasmitted from RX to TX in enp-2611(ixp2400).

To see in chapter 5, 373 immed32(dl_next_block, SPI4_RX_NEXT_BLOCK)

What's Nextblock?

dl_next_block is a context sensitive registers that stores the identifier of the next microblock to which send the packet. It is used within the dl_sink[] macro, in Rx microblock.

#define SPI4_RX_NEXT_BLOCK 0x24

what's difference in ixp2400?

I don't understand your question.

In chapter 5, what's difference between ixp2400 and ixp2800? How to modify in chapter.5 ?

Basically, the SPI4 mode does not exist on IXP2400. You should rewrite configurations steps. Maybe other things should be also changed. I don't know more as I haven't look at the code provided with the book. If you want to program on IXP2400, you'd rather start from SDK reference designs. You will find several designs on SDK Application CD-ROM. If you don't have it, ask your Intel representative.
