I still don't see why you need to do the odd-even swap, but from what you've
described it sounds like it is needed.

Have you chacked out the PCB? It wouldn't be the first time a board
designer had got the top and bottom half of the data bus swapped!

So yes, this looks fine.

You'll need something like this, but the exact values which are programmed
into the registers will depend on the hardware on your board. So you'll
need the timings for the memory you're using.

When the IPL starts up, it looks at some registers, and if they are
set to a particular pattern, it assumes it has been asked to reboot
the OS, and doesn't go into the interactive boot prompt part of the code.
Have a look at where the the get_boot_signature() function is called from.

These registers are normally set by trapping into the IPL to issue a
'shutdown' call, but from the code above, it looks like the SolutionEngines
have a second way of setting this pattern at boot time. 

I know there are some switches on the board which can be read from software,
so maybe that is what it being tested in this bit of assembler code.

I'd remove this bit of code from your version until you have eveything
else working, and then decide if you need a similar mechanism for your
board.

Using my eprom programmer, I do the following steps:
a) I load the sh-stub.srec
b) I swap even-odd byte
c) I program my eprom.

Is this procedure correct?

Thanks.

[linuxsh-dev] sh-ipl+g: What is BOOT_CONFIG_WORD

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

Hi,
how you can easily understand, I'm bot an expert but I'd like to understand 
more.

Following the suggestion of  Stuart Menefy, I'm starting from sesh3 version 
of sh-ipl+g for booting my card.
I have two question:
1) to make working the sh-stub necessarely I need to execute :

	mov.l	RTCSR_A,r1	/* RTCSR Address */
	mov.l	RTCSR_D,r0	/* RTCSR Data */
	mov.w	r0,@r1

	mov.l	RTCNT_A,r1	/* RTCNT Address */
	mov.l	RTCNT_D,r0	/* RTCNT Data */
	mov.w	r0,@r1

	mov.l	RTCOR_A,r1	/* RTCOR Address */
	mov.l	RTCOR_D,r0	/* RTCOR Data */
	mov.w	r0,@r1

	mov.l	RFCR_A,r1	/* RFCR Address */
	mov.l	RFCR_D,r0	/* RFCR Data */
	mov.w	r0,@r1		/* Clear reflesh counter */

	/* Wait DRAM refresh 8 times */
	mov.l	RFCR_A,r1	/* RFCR Address */
	mov	#8,r3
1:
	mov.w	@r1,r0
	extu.w	r0,r2
	cmp/hi	r3,r2
	bf	1b

	mov.l	SDMR3_A,r1	/* Set SDRAM mode */
	mov	#0,r0
	mov.b	r0,@r1


I think so because I need SDRAM.

2) what's the meaning of :

	mov.l	BOOT_CONFIG_WORD,r1
	mov.w	@r1,r0
	exts.b	r0,r0
	cmp/eq	#0xde,r0	! MAGIC # for "doDEs"
	bf	1f
	mov.l	0f,r5
	mov.l	0f,r6
	mov.l	0f,r7
	bra	1f
	 nop
	.align	2
0:	.long 0xbabeface
1:
	rts
	 nop


Thanks a lot.

[linuxsh-dev] NFS issues

[NIIBE Y. <gn...@m1...>]

Here is the change.

Well, it's really difficult (for me) bug to find.

There is disagreement with maintainer of NFS wrt this change, so I
guess that this file will be here a while.

2002-03-20  NIIBE Yutaka  <gn...@m1...>

	* fs/nfs/inode.c (nfs_read_inode): Don't set inode->i_rdev here.
	(nfs_fill_inode): But set it here, instead.
	(nfs_find_actor): Reusing cached inode, clear ->i_mode.

[linuxsh-dev] NFS issues

[NIIBE Y. <gn...@m1...>]

I've added fs/nfs/inode.c to record this change.  It's for linux-2_4
branch only.  When I find it's also there in 2.5, I'll add it
linux-current branch too.

Re: [linuxsh-dev] sh-ipl+g

[Jeremy S. <js...@mv...>]

Not sure I understand why there's an issue with 16-bit versus 32-bit; as
long as the endian is correct and the programming software puts the bytes in
the right place (start from 0 and work your way up) why shouldn't it work?

Building the stub in RAM has several issues: (1) whatever your real boot-rom
is has to initalize the BSC; (2) the stub must NOT re-initialize the BSC;
(3) you've got to pick a place in RAM such that anything else you're using
will avoid stomping on it.  I tried doing this some time ago (I forget
exactly why); the attached patch might be helpful in that regard.

It will build an sh-ramstub.srec which keeps the BSS/Data where the normal
stub does, but moves the text to 0x8D000000, leaving 16M for the kernel
(you'd have to force your kernel to limit itself so as not to overwite the
stub, or configure it to not use the stub and let it overwrite after the
kernel is loaded.  I have not tried this.)  If you want to use sh-ethboot,
of course, you'd need to make similar changes in that (drop -DROM from
CFLAGS in the Makefile, adjust the start address in standalone-ram.lds) and
use a config.h that defines CONFIG_BOOT_LOADER1 to whatever you set the
sh-ethboot start address to.  (And then you've got three pieces of code --
the stub, the loader, and the kernel -- to prevent overlap between.)

Re: [linuxsh-dev] sh-ipl+g

[akira <aki...@ho...>]

No, i don't use the  ipl+g in Area0 because i can't use the flash rom.
The board is little-endian and the rom is 16 bit. (flash rom is 32 bit).
I think that the gcc is right.

Se sei italiano, o se parli italiano scrivimi pure. ho un po' di problemi
con l'inglese.

Re: [linuxsh-dev] sh-ipl+g

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

Were you able to use sh-ipl+g in Area0 ?
Is your board little-endian or big-endian?
How are you sure to compile good for your target?
Is your boot rom 8 or 16 bit?

Thanks

[linuxsh-dev] sh-ipl+g

[akira <aki...@ho...>]

I have a 7727 (SH3-DSP) based board (PFM-DS11), this board uses the =
standard Hitachi layout.
IT is possible to use ipl+g in Area3 (H'0c000000)? and how could i do?

thanks!

Troubles Again
Date: Tue, 19 Mar 2002 17:33:26 +0100
From: Fabio Giovagnini <fg...@ti...>
To: Stuart Menefy <stu...@st...>

I have this problem:

My rom at 0x00000000 is an eprom (M27C4002) with data access 16 bits wide.
I have an eprom with an IPL for winCE working.

When using my eprom programmer I read the working IPL I can read some test in
the ILP with the caracter swapped. For example:
I read form the working eprom "ocypirhg t" and I think it is the word
"copyright ".

When I compile my sh-ipl+g I see the text in the rigth way when I open
sh-stub.srec

I'm sure my board is little-endian (we have to remeber it works win winCE).

How can I make myself sure that I'm compiling correctly and I'm writing
correctly the eprom?

Thanks in advance.

He just doesn't like 'em on x86.  As far as I know he's never
compilained about KGDB support on PPC, or xmon (very light debugger)
being in the tree.
