Re: [linuxsh-dev] patches for strace on SuperH

[Stuart M. <stu...@st...>]

strace shows you which systems calls a program is making. It is very
useful for tracking down why a program isn't working without having to use
a debugger or adding printf's.

For example, you can see which order a set of configuration files are being
read, without having to understand the source code or refer to the
documentation!

[linuxsh-dev] patches for strace on SuperH

[Daniel J. <dj...@sy...>]

Hi all,

in August 2001, Greg Banks and Stuart Menefy were exchanging several
patches on this
mailing list. The purpose of these patches was to enable strace for
SuperHitachi.
Unfortunately, the mailing list archive shows EMails without
attachement, thus I cannot
see the patches.

Does anyone still have these patches or does anyone know where I may get
them (or
other patches related to the same purpose).

Any hints are highly appreciated.

As I am not a member of this list it would be nice if you'd CC me.

Thanks in advance

	Daniel

Here's my take on it:

1) I don't think it matters how you link it, as long as it knows where it wants
to be in RAM.
2) You can load w/gdb as long as you're talking to an independent stub.  The stub
and app have to agree on (a) serial port usage, and (b) exception handling; this
is necessary whether the app and stub are linked together or not.
3) There's the rub: I've not used the SH2, but from what little I know it's
very different than the SH3/4 in terms of exception handling and register set.
Not only would you need to write the BSC init for your board (like any port) but
you'd need to rewrite entry.S to deal with the fact that exception vectors are
addresses rather than code blocks, there are no bank registers, etc; the stub
itself my need to change the register handling if the stacked register set looks
different (but that also depends heavily on what the gdb the stub is talking to
expects).  Even the serial ports (if available) may be different, requiring work
in sh-sci.c too...

The upshot is that I don't think the SH3/4 version will "drop in" easily.  (But
there might be an SH2 version floating around... in fact, I think if you look at
the GDB package there might be some sample stubs there, and the SH one might be a
good SH2 starting point for linking with your app?)

[linuxsh-dev] Question : GBD Stub to boot a machine.

[Fabio G. <fg...@ti...>]

Hi, every body,
I'm woking on porting linux-sh on a my own sh-3 based board.
To debug the software regarding the machvect description, I boot my card 
using sh-ilp+g and everything works good.
Now I'd like to put on the flash of another my development sh-2 based card 
the gdbstub I found on sourceforge to achieve the following target:
1) power up my card;
2) load on ram my program;
3) execute from ram my  program;
4) debug it.

Some doubts:
1) How do I have to link my application program I like to debug using gdbstub?
2) Is it possible to use gdbstub to debug a loaded program (using (gdb) load 
/root/myrog command); or gdbstub has to be a part of my application program?
3) Can I try to compile sh-ipl+g for may sh-7044 based card, or it has too 
much specific part sh-3 and sh-4 related?

Thanks for your answer.

The patches for 3.0.x, except very temporary ones, were sent
to the GCC list. But many of them are too late for 3.1. 3.1 is
already released and non bug-fix patches will not be approved
for it. So some patches will be integrated in 3.2 only.

Anyway, I put a temporary patch for gcc-3.1 branch as

  http://dodo.nurs.or.jp/~kkojima/gnu-on-sh/gcc-3.1-branch-tmp.diff.gz

Please don't take it as a stable thing. If you try it, the
regeneratable files (some Makefile.in and configure files)
should be regenerated. Recently I can build and install GNU
libc with it, but it stays at the level of "working for me".

BTW, now mainline (3.2) has the new configury method for SH
target and the fairy large part of our local patches become
unneeded.

[linuxsh-dev] My family needs your assistance

[<ped...@ne...>]

From: Pedro Savimbi

This letter may come to you as a surprise due to the
fact that we have not yet met. The message could be
strange but real if you pay some attention to it. I
could have notified you about it at least for the sake
of your integrity. Please accept my sincere apologies.
In bringing this message of goodwill to you, I have to
say that I have no intentions of causing you any
pains.

I am Mr. Pedro Savimbi, son of the late rebel leader
Jonas Savimbi of Angola who was killed on the 22nd of
February 2002 . I managed to get your contact details
through the internet myself Time is of the importance 
and I was desperately looking for a person to assist 
me in this confidential business.

My late father, Jonas Savimbi  was able to deposit a
large sum of money in different security firms in 
Europe and Ghana. My father is presently death and 
the movement of his family members (including me) 
is restricted. We are forbidden to either travel 
abroad or out of our localities. Presently our 
movement are monitored. Right now there is a rush 
for all my Father's wealth but home and Abroad by 
the Government who are claiming that most of the 
wealth was got by Arms smuggling and therefore 
illegal and by my father,s extended family and 
relations.

You can know more about my father by checking his 
profile at URL below:   www.kwacha.com/edoc2.htm 

His wealth has been estimated to be $500 million 
to over $1 billion and being close to my father 
I happen to be in possession of documents 
and information of some of the wealth.Approx. 
$250 million and only my trusted mother knows 
that I have this information.

Presently, the US$100,000,000.00 (One Hundred 
Million Dollars) cash and precious materials
my father moved to Ghana before his death is 
deposited with some security firm . Before 
you can get access to it I have to give you the 
some hits.

I am therefore soliciting your help to travel to 
Ghana in west Africa to recieve this money and 
transfer into your account before my government 
get wind of this fund .You know my father was a 
rebel leader in Angola before his death. My 
reason for  doing this is because it will be 
difficult for the  Angolan government to trace 
my father's money to an individual's account, 
especially when such an individual has no 
relationship,I decided to keep that money for 
my family use. At present the money is kept 
with some Security Companies in Ghana

I am currently and temporarily living in Angola
and as refugee status,I intend to communication 
with you as regards this transaction on a 
satellite phone to avoid intervention by anybody.

Moreover, the political climate in Angola at the
moment being so sensitive and unstable.With this
password and information and I will send you a
power of attorney to the security firm, When you
are ready I will give you the information needed
before you can get access to 7,000kg of AU gold dust, 
8500kg of pure Diamond and raw cash of USD100 million 
America dollars. you will then proceed to Ghana for 
collection.

PLEASE  YOUR CONFIDENTIALITY IN THIS TRANSACTION IS 
HIGHLY REQUIRED.


Yours sincerely,
Pedro Savimbi.

You do, and you also probably want --adjust-vma or --adjust-start or
something, since starting with a binary image, address 0 will be used by
default.  You may with to start with the compressed/vmlinux (ELF) rather
than zImage (binary).  The zImage rule in boot/Makefile already does an
objcopy; a nearly identical zImage.srec rule which simply adds -O srec may
produce what you want:

  zImage.srec: $(CONFIGURE) compressed/vmlinux
        $(OBJCOPY) -O srec compressed/vmlinux zImage.srec

  zImage: $(CONFIGURE) compressed/vmlinux
       $(OBJCOPY) compressed/vmlinux zImage

Note however that even with this the address you get is one in RAM where
the vmlinux ELF file expects to be.  If you are planning to load this in
flash as implied by your earlier email, you may need to change things.
Some comments on that below.

Note that this means the kernel (decompressor) actually needs to be linked
to run at the address its put: if you jump to code at location X which is
built expecting to find itself at location Y it won't work too well...
obviously you can change CONFIG_BOOT_LOADERx definitions and rebuild
sh-ipl+g as well.

That said, the normal "zImage" build expects to find itself in RAM at
0x8N210000, where N is the CONFIG_MEMORY_START (see
arch/sh/boot/compressed/Makefile).  [Hmmm... this seems to be an effort to
leave at least the first 2M+64K of RAM available for the decompressed
kernel, but you claim to have only 2M to begin with?]

If you want to have the kernel in flash so sh-ipl+g will jump to it and
have it decompress itself into RAM, you can build the kernel slightly
differently.  If I remember, I'll attach a patch I was playing with to do
this (already on this list last month I think; includes a configurable
kernel cmdline as you don't have sh-ethboot to build one for you in this
case).  [This allows you to specify a flash address and changes zImage to
do that -- but I think making a target like fzImage or something would be
better.]

One idea might be to get more RAM on your board; I wouldn't be surprised
if your kernel finds 2MB to be a tight squeeze...

Well, that's not the right arguments :) Try:
sh-linux-objcopy -O srec --srec-forceS3 zImage zImage.srec

I'm not sure if you need the -I binary or not..

Dear all,

I have to convert  a compressed kernel for an SH37727
based board to a Motorola S3 format file.
Is it possible?

I tried using sh-linux-objcopy -I binary -O srec
zImage zImage.mot .
But this commmand is showing the help message.

Does any one know how to convert a compressed kernel
image to an S3 format file?

Thanks and regards,
Manoj K.S

Yes. That's what its designed for.

No. The compressed kernel has its own decompression
loader at the beginning, which decompresses the code from
ROM into RAM. So when you tell sh-ipl to jump to the
'compressed kernel', you are actually jumping to the
decompression code (which is obviously not compressed!).

Yes. You need a root file system for the kernel to load the
application code from. This can be on any media though, NFS,
hard drive, or Flash.

[linuxsh-dev] How to pass the control from SH IPL+g to compressed kernel for SH7727 Based board?

[<mks...@ya...>]

Dear all,

I have downloaded the SH IPL+g  and the kernel to the
Flash ROM of my Hitachi SH3 7727F processor based
board having 2MB SDRAM and 4MB Flash ROM 
I am getting responses in my Tera Term Pro serial port
emulator.But i dont know how to pass control from sh
ipl+g to the compressed kernel.

I have read the LinuxSH FAQ.But i have some specific
doubts.
1) How to pass the control from SH IPL+g to the
compressed kernel?
I know that in sh ipl+g "1" and "2" commands can be
used to jump 
to predefined locations (CONFIG_BOOT_LOADER1,
CONFIG_BOOT_LOADER2) .
Is it okay that i put the compressed kernel in any of
the above location?

2) whether SH IPL+g will decompress the kernel and
transfer to RAM?

3) Where comes the role of file system? Do we need a
file system for porting linux to a development board?

Could any please share some ideas in the matter,i will
be very thankful

Regards,
Manoj K.S

Attached is a patch against kernel 2.4.17-st1.0 that contains the =
necessary changes to arch/sh/mm/cache-sh4.c for the associative cache =
mode on the SH7751R. It introduces a new cpu subtype, =
CONFIG_CPU_SUBTYPE_SH7751R, which must be selected for the associative =
cache option to be available.

The modifications were made to the 2.4.17 SH4 kernel released by ST as =
beta 1.0, and the patch was generated against this kernel version. For =
various reasons, we have not been able to get this kernel to run on =
SH7751R silicon, so it is offered as a work-in-progress in the hope that =
it will be useful. At least, it can serve as a guide to anyone making =
the same changes to a more recent kernel.

The patch also contains some irrelevant changes related to DTF. These =
should not cause any problems.

Thanks for your fast reply!
A few more questions to get me started..

Which CVS do you mean?  I dont see anything in the
sourceforge repository, is there another linuxsh CVS?

I would eventually like to be building my own
toolchain and aim to have gcj support at some point. 
Right now I'm looking for a good starting point.  I'll
try 3.0.4.

Thanks for your help,

mt

I'm not certain about your problem, but gcc-3.1 for SH may
require the newer binutils which can be got from CVS.

BTW, gcc-3.1 has problems for sh-unknown-linux-gnu target.
The locally patched gcc-3.0.4 and binutils are more stable
for SH. If your goal isn't toolchain itself, it's much better
to use their RPM version. Please check

  http://mirror.sh-linux.org/rpm-index/index.html

for example.

[linuxsh-dev] compiler tools, and some observations

[mt <red...@ya...>]

Hello,

I tried to build a gcc-sh (3.1) with the latest
binutils (2.12.1) using --target=sh-linux-gnu (is this
correct?) for both.  It appears that the tools do not
work together very well, giving the following error
while building gcclib:

/tmp/cc4CqyU9.s:111: Error: Rest of line ignored.
First ignored character is `-'.

the line in question is:

	.long	___cxa_finalize@PLT-(.LPCS1+2-(.))



do gcc-3.1 or binutils-2.12.1 not support sh-linux
correctly?  if not, what versions do?  or am I doing
something else wrong?

also, http://linuxsh.sourceforge.net/ doesn't seem to 
be very up-to-date, it doesn't even mention this list.
 who is in charge of it, and would they (you?) accept
changes/additions?


thanks
mt
