Hi, I have an Intel IXDP465 target with a NPE-B mezzanine card and that was supported & validated with linux-2.6.21 + "Intel IXP400 Software Access Library". And now the NPE ether net driver moved into the linux baseline (drivers/net/arm/ixp4xx_eth.c) so I want to try it without Intel's lib but failed. Here is my operations: Build the zImage with linux-2.6.28, I configure the kernel with ixp4xx_defconfig and just change the IXP4XX_ETH to Y. Build the firmware for NPE-B: -) download the "Intel(R) IXP400 software - Access Library (non-crypto)" to get the head file IxNpeMicrocode.h; -) download the "Intel IXP400 software - NPE microcode (non-crypto)", both 2.4 and 3.0/3.0.1 version, unpack it and copy the head file IxNpeMicrocode.h to its source code subdirectory; -) Edit the head file and comment out those macros for NPE-A and NPE-C and just leave the one for NPE-B; -) Edit the IxNpeMicrocode.c and comment out line 25664, the 8 bytes of "END OF IMAGE LIBRARY MARKER". -) "gcc ixNpeDlImageConverter.c" and get a a.out; run it and get the firmware called IxNpeMicrocode.dat. -) Rename the IxNpeMicrocode.dat to NPE-B and copy it to the NFS rootfs of the target in /lib/firmware. There is a PCI E100 NIC and the linux kernel mount NFS rootfs through it. The kernel can find two NICs related to NPE, eth1 for NPE-B and eth2 for NPE-C. Then, I tried to active the NIC of NPE-B(eth1): -) "ifconfig eth1 hw ether 1234567890ab 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255". With this I can see the driver output "eht1: link up, speed 100 Mb/s, full duplex". -) Then "ping -I eth1 192.168.1.2". Then all I can get is "Destination Host Unreachable" :-( With the firmware built with Microcode-V2.4, it can send up to 6 packages(get tx irq) and at last the "Link is down"; with the firmware of V3.0, no package TX and at last the TX queue full and was deactivated. With both of these firmware, no packages received. I wonder if there are anything wrong with my operations or if I need some other special configurations/operations? Or any advises on debugging that.
