[linuxdc-dev] Question about bootstrapping. . .

[ZhayTee <zh...@zh...>]

Using the kernel-boot and sh4-cross-tools package provided on the
sourceforge linuxdc project page, I managed to create a working
1ST_READ.BIN, or so I thought. Unfortunately, my dreamcast reboots after
showing the SEGA license screen, so it's obviously not working properly. I
can successfully burn and boot a disc featuring a 1ST_READ.BIN which hasn't
been created on my system (such as the one which exists on the distribution
by the cool and froody guys at m17n.org; it's just the ecos bootloader, but
it does load properly), so it's rather obvious that I'm doing something
wrong at some point when building my 1ST_READ.BIN.

The only place I can see an error is here:

[root@slartibartfast] ~/dc/kernel-boot# make kernel-boot.bin
sh4-linux-objcopy -I binary -O elf32-sh-linux zImage.bin zImage.o
sh4-linux-objcopy: Warning: Output file cannot represent architecture
UNKNOWN!
sh4-linux-objcopy -I binary -O elf32-sh-linux initrd.bin initrd.o
sh4-linux-objcopy: Warning: Output file cannot represent architecture
UNKNOWN!
sh4-linux-gcc -ml -m4 -o kernel-boot.elf kernel-boot.S zImage.o
initrd.o -nostdlib -nostartfiles -T boot.lds
sh4-linux-objcopy -O binary kernel-boot.elf kernel-boot.bin
[root@slartibartfast] ~/dc/kernel-boot#

The kernel-boot.bin file is created, but those warnings from objcopy don't
exactly look healthy.

Any help would be appreciated. I'm so close, yet so far. :P
