Using Hardhat linux targeting a NEC VR5432 and a 2.4.0-test 5 kernel I
get an image that looks like the following:

vmlinux:     file format elf32-littlemips

Disassembly of section .text:

0000000080001000 <_ftext>:
 ...
    80002000: 6e 01 00 10 00 00 00 00 00 00 00 00 00 00 00 00
n...............
 ...

0000000080002288 <except_vec0_r4000>:
....
00000000800025bc <kernel_entry>:

--------------------------------------
using the cvs 2.4.3 kernel (about a week old) and the same tool chain I
get an image that looks like:
Using a loadaddr of 8000000

vmlinux:     file format elf32-littlemips

Disassembly of section .text:

0000000080000000 <_ftext>:
    80000000: 6b 01 00 10 00 00 00 00 00 00 00 00 00 00 00 00

 ...

0000000080000288 <except_vec0_r4000>:
....
00000000800005b0 <kernel_entry>:
 ...

--------------------------------------
If I change the loadaddr to 80001000 I get:

vmlinux:     file format elf32-littlemips

Disassembly of section .text:

0000000080002000 <_ftext>:
    80002000: 6b 01 00 10 00 00 00 00 00 00 00 00 00 00 00 00
k...............
 ...

0000000080002288 <except_vec0_r4000>:
....

00000000800025b0 <kernel_entry>:


-------------------------------------

No matter what I do I can not get _ftext to appear at 80001000. I use
identical ld.scripts for bother kernels.
At first I thought it was my binutils so I switched to the same tools
that I used with my 2.4.0-test5 kernel.

Addresses appear to be off by 0x1000.  Which is why my 2.4.3 kernel dies
on the jump to init_arch out of kernel_entry.

Any thoughts about what I might be doing wrong?


Thanks,
Scott
