Note: These steps may no longer be necessary. I did a fresh install from the 2008-08-31 trunk, and /lib/firmware/NPE-* files were created and detected automatically.

In order to use the ethernet ports on this router, you have to build the Intel NPE-B and NPE-C microcode binaries, concatenate them together, and write them into a flash partition with the name "microcode".

• Dig through the Intel site until you find IPL_ixp400NpeLibrary-2_4.zip. Good luck!
• Extract the zip file, and go to ixp400_xscale_sw/src/npeDl. You should see a couple .c files there.
• Download IxNpeMicrocode.h from OpenWRT. (There's an "Original Format" link at the bottom.)
• By default, IxNpeMicrocode.h is configured to build the Crypto version of NPE-C, which is not easy to obtain. Edit the .h file to uncomment only the basic non-Crypto versions:

#define IX_NPEDL_NPEIMAGE_NPEB_ETH_LEARN_FILTER_SPAN_FIREWALL #define IX_NPEDL_NPEIMAGE_NPEC_ETH_LEARN_FILTER_SPAN_FIREWALL

• Compile, run, and concatenate the binaries:

$ gcc IxNpeMicrocode.c $ ./a.out Writing image: IXP425.NPE_B Func: 0 Rev: 02.01 Size: 11964 to: 'NPE-B.01000201' Writing image: IXP425.NPE_C Func: 0 Rev: 02.01 Size: 11964 to: 'NPE-C.02000201' $ cat NPE-B.01000201 NPE-C.02000201 > microcode.bin

• And, assuming you've figured out how to use Redboot and TFTP:

load -r -b %{FREEMEMLO} microcode.bin fis create microcode
