Hi~~^^ I don't understand to following step! chapter 5 ixp2400/2800 programming original source --------------------------------------- _spi3_rx_move_rbuf_to_dram(rsw.w1.parts.element, cur_mpacket_addr, rsw.w1.parts.byte_count, &rbuf_to_dram_sig); // Update the buffer length dlMeta.bufferSize += rsw.w1.parts.byte_count; // Wait for the mpacket to move into DRAM __wait_for_all(&rbuf_to_dram_sig); _spi3_rx_free_rbuf(rsw.w1.parts.element); // If this is the EOP mpacket then return if (rsw.w1.parts.eop) { break; } // Update the reassembly pointer cur_mpacket_addr += rsw.w1.parts.byte_count; --------------------------------------- I think so to follow. --------------------------------------- _spi3_rx_move_rbuf_to_dram(rsw.w1.parts.element, cur_mpacket_addr, rsw.w1.parts.byte_count, &rbuf_to_dram_sig); __wait_for_all(&rbuf_to_dram_sig); dlMeta.bufferSize += rsw.w1.parts.byte_count; cur_mpacket_addr += rsw.w1.parts.byte_count; if (rsw.w1.parts.eop) { break; } _spi3_rx_free_rbuf(rsw.w1.parts.element); --------------------------------------- what do you think about? Thank you so much in advance!

Hi, I wonder how I might get file info, such as size from the nfs mount on the ixp1200. Is there something like the syscall stat(file, buf) available? -- Øyvind Hvamstad <oyvindh(a)ifi.uio.no>

Hello~~^^ I was developed to sdk 3.1 in ixp2400. Um... I buy ixp2400/ixp2800 Programming on Amazon. MSF device is SPI4 in ixp2800 but ixp2400 is POS-PHY Level 3. What kind of difference ixp2800 and ixp2400? I hold only one of scratch ring for single PHY. Therefore, scatch ring size hold 1024. Right ? ... ... MSF_interrupt_status = 0x0000 0e00 May be, no rbuf element was free to accept mpacket. Please, solve me~~! Thanks in advance.
