hmm... ^^^^^^^^
I don't understand... ;-<
you Sheevaplug happen software-interrupt-exception at 0x8008. netbsd's
entry point is 0x8000.
Can you try ?
# arm--netbsdelf-objdump -d your-SHEVAPLUG/netbsd
c0008000 <marvell_start>:
c0008000: ee104f10 mrc 15, 0, r4, cr0, cr0, {0}
c0008004: e3c4400f bic r4, r4, #15 ; 0xf
c0008008: e28f50c4 add r5, pc, #196 ; 0xc4
c000800c: e28f60c8 add r6, pc, #200 ; 0xc8
Do you try to boot my test kernel?
# I replaced cpufunc_asm_sheeva.S to FreeBSD's.
# I see message "/etc/rc.conf is " from /etc/rc. And, it hung up. ;-)
Thanks,
