I have port (by a company Im working for) to ixp420 last month. That would not be fit in your kernel.A standard kernel 22.214.171.124 has been successful to port on kixrp435(ixp435 reference platform) dev-board recently. Im gonna share with you guys about it. There are few stuffs you need to get before you start the hack.
1,Download the files that you will use
2,try to get a cross-compiler(I have been using a customized GNU toolchains by timesys).My armv5b-linux-gcc version is 3.4.1-7
3,Of course you need a kernel-126.96.36.199
4(optional), you can use the rootfs I created.
I totally agree with Ken Thompson said"This is a consequence rather than a goal. I abhor a system designed for the "user", if that word is a coded pejorative meaning "stupid and unsophisticated". That's a good reason dont be expected the doc(or is called "log") might be readable as a literature. I'm writting this for hackers but not as users. Hope can helps.
May Lord's hacking spirit guide us!
#tar jxvf linux-188.8.131.52
#cp -r linux-184.108.40.206/arch/arm/mach-ixp4xx/include/mach linux-220.127.116.11/include
#cp linux-18.104.22.168/arch/arm/include/asm/* linux-22.214.171.124/include/asm/
do "source ixp400_xscale_sw/buildUtils/environment.linux.sh" after you have already set the right path in: ixp400_xscale_sw/buildUtils/environment.linux.sh
Copy the Makefile and Kconfig to your kernel directory that may be:linux-126.96.36.199/driver/net
#cp ixp400_eth.c IxLinuxEDDIoctl.h linux-2.6.28/driver/net
#cp config.bak linux-188.8.131.52/
#cp semaphore.c linux-184.108.40.206/kernel
#cp semaphore.h linux-220.127.116.11/include/linux
replace "consistent_sync" with "dma_cache_maint"
1,add #include "linux/fs.h"
2,comment these 3 lines:
/* if (unregister_chrdev(DEV_IXNPE_MAJOR_NUMBER, "ixNpe"))
printk (KERN_ERR "Failed to unregister driver for
And,add a line above it:
replace "SA_SHIRQ" with "IRQF_SHARED"
check your kernel config
# make $IX_KBUILD_CROSSCOMPILE menuconfig
# make $IX_KBUILD_CROSSCOMPILE
compile npe driver
# cd ixp400_xscale_sw
# make all
then you will get 3 files(ixp400.ko,IxNpeMicrocode.dat,ixp400_eth.ko)
that's all your ixp435 platform needs.
# insmod ixp400.ko
ixp400: module license 'unspecified' taints kernel.
# cat IxNpeMicrocode.dat > /dev/ixNpe
# insmod ixp400_eth.ko
ixp400_eth: Initializing IXP400 NPE Ethernet driver software v. 1.8
ixp400_eth: CPU clock speed (approx) = 398 MHz
ixp400_eth: Found PHY 0 at address 1
ixp400_eth: Found PHY 1 at address 2
ixp400_eth: Found PHY 2 at address 3
ixp400_eth: Found PHY 3 at address 4
ixp400_eth: Found PHY 4 at address 5
ixp400_eth: ixp1 is using NPEC and the PHY at address 1
ixp400_eth: ixp2 is using NPEA and the PHY at address 2
ixp400_eth: Use default MAC address 00:02:b3:02:02:02 for port 1
ixp400_eth: Use default MAC address 00:02:b3:03:03:03 for port 2
btw:I found a community the named openixp provided many FOSS solutions on ixp platform.unfortunately, it seems it was not update for a "while"
