Hi, I'm trying to boot current Linux kernel with patches from OpenWRT on an Infineon Easy5120-RT but without the LZMA loader. Hence I mimic what patches from http://nano.gmxhome.de/linux-2.6.17.11-adm5120-patch.diff.gz and http://www.student.tue.nl/Q/t.f.a.wilms/adm5120/files/linux-2.6.12-rc1-adm.diff (I have verified myself that the later boots, as also the 2.6.22 with the LZMA does) do - use 0x80002000 as LOADDADD instead of 0x80001000, and fill to 0x6d8 + jump to kernel_entry in head.S, but the resulting vmlinuz doesn't boot. There is some info at http://www.linux-mips.org/wiki/Adm5120#Linux_Support diff -urNdp linux-2.6.22.9-vanilla/arch/mips/Makefile linux-2.6.22.9/arch/mips/Makefile --- linux-2.6.22.9-vanilla/arch/mips/Makefile 2007-09-26 20:03:01.000000000 +0200 +++ linux-2.6.22.9/arch/mips/Makefile 2007-10-10 20:44:24.000000000 +0200 @@ -165,6 +165,13 @@ cflags-$(CONFIG_MACH_JAZZ) += -Iinclude/ load-$(CONFIG_MACH_JAZZ) += 0xffffffff80080000 # +# ADMtek 5120 +# + +core-$(CONFIG_MIPS_ADM5120) += arch/mips/adm5120/ +load-$(CONFIG_MIPS_ADM5120) += 0xffffffff80002000 + +# # Common Alchemy Au1x00 stuff # core-$(CONFIG_SOC_AU1X00) += arch/mips/au1000/common/ diff -urNdp linux-2.6.22.9-vanilla/arch/mips/kernel/head.S linux-2.6.22.9/arch/mips/kernel/head.S --- linux-2.6.22.9-vanilla/arch/mips/kernel/head.S 2007-09-26 20:03:01.000000000 +0200 +++ linux-2.6.22.9/arch/mips/kernel/head.S 2007-10-10 20:44:24.000000000 +0200 @@ -134,6 +134,11 @@ * Necessary for machines which link their kernels at KSEG0. */ .fill 0x400 +#ifdef CONFIG_MIPS_ADM5120 + /* ADM5120 bootloader jumps to 0x6d8 */ + .fill 0x2d8 + j kernel_entry +#endif EXPORT(stext) # used for profiling EXPORT(_stext) Any clues what I am missing or what I do wrong?
