[linux-sh:03381] Re: Booting Linux on HP 620LX - shlo syntax problem

So far I went w/ hpcboot on the HP Jornada 620lx:

Successful boot of kernel using hpcboot
=======================================
netbsd-GENERIC
--------------
netbsd GENERIC Kernel hpcsh

The kernel boots fine, keyboard works. I haven't gone to root filesystem for
an interactive system. But that seems to me like peanuts ;-)

jahns@condor sh3 > file netbsd-GENERIC-boots-OK
netbsd-GENERIC-boots-OK: ELF 32-bit LSB executable, Hitachi SH, version 1
(SYSV), statically linked, not stripped

Boot not successful
===================
Linux from dodes.org
--------------------
- hpcboot loads the kernel
- still loading under WinCE window pops up: "no symbol and/or string table
in binary (not fatal)"
- black screen on the jornada turns up with the HP copyright string
- printed "Booting warm ..."
- printed "exception event code = 100"
- printed "Address Error (store)"

jahns@condor sh3 > file vmlinux-hp620
vmlinux-hp620: ELF 32-bit LSB executable, Hitachi SH, version 1 (SYSV),
statically linked, stripped


Linux from jlime.com
-------------------
hpcboot refuses to boot this kernel.

jahns@condor sh3 > file sh3-k2.6.4-hp620
sh3-k2.6.4-hp620: Linux Kernel, Setup Version 0x202, bzImage, root_dev
0x9, swap_dev 0x9, RAMdisksize 9 KB, Video mode 9
Linux from BlandLinuxCE
------------------------
hpcboot refuses to boot this kernel.

jahns@condor sh3 > file zImage-HP620
zImage-HP620: data


Somehow the file type determines if hpcboot can boot a kernel image or not.
The netbsd kernel is not stripped, the dodes Linux kernel is (but does
this mean it will not boot because of this?).


Ah, as I see from Philipp's hint to the Jornada 720 website
(http://acid.ch.pw.edu.pl/~sq5bpf/mylinux/linux-jornada720/) :

"Hpcboot is able to load ELF objects"

So the question for me is:
How do I transfrom the Jlime Linux kernel into an ELF exec?
Could you comment on this, please?

Actually, hpcboot is picky about filenames, but for me it was _not_ necessary
- to copy the kernel to a specific place ( it was in the root of the
storage card)
- to attach a serial cable to the jornada, though it is nice to watch the
kernel boot over serialline.
