Is gzboot required to boot kernels on ARM/XScale platforms?
I have a kernel image which I am trying to boot on an XScale XDP425 board and
Redboot gives me only some garbage ASCII output (see below).
did not result in anything positive either.
Unfortunatelly I was unable to find any man page or info on the netbsd.org
website about gzboot and I am a bit confused about it's purpose and usage
There is basically very little info about this process and I'd like to
understand and document it.
I altered src/sys/arch/evbarm/conf/mk.ixdp425
so it shows:
so it shows:
.word 0x01600000 - 0x4000
Then I created two partitions on the FLASH.
The one for kernel is about 1.6M so the gziped kernel will fit:
fis create -b 0x01600000 -f 0x50080000 -l 0x00186A00 -e 0x01600000 -r
0x01600000 -n kernel
fis create -f 0x50220000 -l 0x005C0000 -n ramdisk
Redboot shows there is 64M RAM and 8M FLASH memory on it:
