Hi All, hot to debug my eth0' hw?

[Fabio Giovagnini]

Hi all, I build a board with smsc 9118 eth chip; Of course I'm not sure the hw 
is ok.
I'm think to boot with nfs root with no success with these messages:

tring to ping as no effect.
I'm sure the IPR register is properly set.
How can I debug my proble?
Could you sugget me a robust and fast way?

Thanks in advance

Not sure what is missing in your case, but if you want top optimize
your performance then this commit may be helpful:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h£0c89ad41099f58922e0941e346e7c4371655b9

Re: Hi All, hot to debug my eth0' hw?

[Fabio Giovagnini]

Thanks a lot, but 2 questions.
1)I'm using linux2.6.16-ucinux-7203; with the oscilloscope i can se that after 
chip reset by the driver the irq line is driven low and stays always low. I 
think the is not proper because this means that never the chip irq state flag 
is erased

2) I have a 32 bus connected sh2a D0 do smc9118 D0 and sh2a D31 do smc9118 
D31; do I need a software swap? ( I followed the schematics of rsk+ 7203 eva 
board before to learn that for big endioan processors the designer needs to 
physically swap the bytes).

Best regards and thanks a lot

Why are you using such an old kernel? It's more than 3 years old!!!

I've added code to enable swap on upstream for the rsk7203. It was
needed by big endian platforms.

Please use a newer kernel if possible.

Cheers,

Re: Hi All, hot to debug my eth0' hw?

[Fabio Giovagnini]

After I'll be able to have busybox I'll try to do it for sure.
Which one you suggest to me?

I recommend 2.6.34-rc2 or later. Even better, use git to get the
latest kernel tree.

PAUL TOLD ME TO USE THIS:
git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6.git


Is ti ok?

Thanks a lot

Look here:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;hr4cfb944007b7f8d346523a7810b53a35921bc5

> Please use a newer kernel if possible.

If you use the latest kernel then the fixes above are already included.

I recommend you to use the sh-2.6 git tree for development.

Thanks,

Re: Hi All, hot to debug my eth0' hw?

[Fabio Giovagnini]

Hi Magnus,
yesterday I used the following command
 git clone  git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6.git

Am I ok?

My configuration is :

SH2a 7203			smc9118
Addresses:
A1...A7				A1...A7
Data:
D0...D31				D0...D31

when I execute
static int __init smc911x_probe(struct net_device *dev, unsigned long ioaddr)
{
	struct smc911x_local *lp = netdev_priv(dev);
	int i, retval;
	unsigned int val, chip_id, revision;
	const char *version_string;
	unsigned long endian;

	DBG(SMC_DEBUG_FUNC, "%s: --> %s\n", dev->name, __FUNCTION__);

	activedev = dev;

	/* First, see if the endian word is recognized */
	val = SMC_GET_BYTE_TEST();
	DBG(SMC_DEBUG_MISC, "%s: endian probe returned 0x%04x\n", CARDNAME, val);
	if (val != 0x87654321) {
		DBG(SMC_DEBUG_MISC, "%s: swapping endianness of card \n", CARDNAME);
		
		endian = SMC_GET_ENDIAN();	
	
		SMC_SET_ENDIAN(~endian);
		SMC_SET_ENDIAN(~endian);

		val = SMC_GET_BYTE_TEST();
		DBG(SMC_DEBUG_MISC, "%s: endian probe returned 0x%04x\n", CARDNAME, val);
		if (val != 0x87654321) {
			printk(KERN_ERR "Invalid chip endian 0x%x\n",val);
			retval = -ENODEV;
			goto err_out;
		}
	}

if I use 
/* 4567_0123 --> 0123_4567 */

#define SWAPDW(x)	( (_uint32)(  (((_uint32)x & 0x0000FFFF) << 16) | \
                                  (((_uint32)x & 0xFFFF0000) >> 16) ) )

//#define SWAPDW(x) (x)

/* 2301_6745 --> 0123_4567 */

#define SWAPDB(x)	( (_uint32)(	(((_uint32)x & 0x000000FF) << 8) | \
					(((_uint32)x & 0x0000FF00) >> 8) | \
					(((_uint32)x & 0x00FF0000) << 8) | \
					(((_uint32)x & 0xFF000000) >> 8)) )

//#define SWAPDB(x) (x)

The check fails;
If I use
/* 4567_0123 --> 0123_4567 */
/*
#define SWAPDW(x)	( (_uint32)(  (((_uint32)x & 0x0000FFFF) << 16) | \
                                  (((_uint32)x & 0xFFFF0000) >> 16) ) )
*/
#define SWAPDW(x) (x)

/* 2301_6745 --> 0123_4567 */
/*
#define SWAPDB(x)	( (_uint32)(	(((_uint32)x & 0x000000FF) << 8) | \
					(((_uint32)x & 0x0000FF00) >> 8) | \
					(((_uint32)x & 0x00FF0000) << 8) | \
					(((_uint32)x & 0xFF000000) >> 8)) )
*/
#define SWAPDB(x) (x)

That means no swap it seems to work but really fails.

My hw configration is good for actual version of the kernel driver or I need to 
be carefull to other stuff?

Thanks a lot again

For the kernel please use the latest codesourcery toolchain. Actually,
in general, please try the latest version of any software before you
report any issues.

For sh2a user space I'm not sure.

The kernel builds just fine for me:

Please check the patches I pointed out earlier again. Read the commit
messages, big endian data transfer is broken on rsk7203 without the
patches. Register access is ok without swap but FIFO (actual data) is
broken.

If your ethernet hardware design is identical to rsk7203 then you will
need the patches.
Remember to set SMSC911X_SWAP_FIFO, i think that will solve your issue.

The latest kernel should be just fine on rsk7203. At least it builds. =)

Re: Hi All, hot to debug my eth0' hw?

[Fabio Giovagnini]

I have downloaded the sourceryg++-4.4-46-sh-linux-gnu.bin
I received an email telling me that the evaluation copy will expire in april.
I'll lose the available support or the toolchail will stop to work?

This is the first time for me with codesurgery

Thanks a lot

The toolchain provided by "Sourcery G++ Lite Edition" does not expire.

This si not patched with SMSC911X_SWAP_FIFO;

Could you tell me the git command I have to use to download the patched one?

Thanks

It certainly is there in my tree:

damm@t400s ~/git/sh-2.6 $ git log -1 --oneline | head -n 1
3f7581d serial: sh-sci: remove duplicated #include
damm@t400s ~/git/sh-2.6 $ grep SMSC911X_SWAP_FIFO
arch/sh/boards/mach-rsk/devices-rsk7203.c
	.flags		= SMSC911X_USE_32BIT | SMSC911X_SWAP_FIFO,
damm@t400s ~/git/sh-2.6 $ grep SMSC911X_SWAP_FIFO drivers/net/smsc911x.c
	if (pdata->config.flags & SMSC911X_SWAP_FIFO) {

Re: Hi All, hot to debug my eth0' hw?

Is it accessible by me for example
git://git.kernel.org/pub/scm/linux/kernel/git/magnus/sh-2.6.git

or not?

You don't need any speical tree or patches. The normal sh-2.6 tree
should include all you need. Please try using the same commands as me
below:

Check last commit in git branch/tree:

damm@t400s ~/git/sh-2.6 $ git log -1 --oneline | head -n 1
3f7581d serial: sh-sci: remove duplicated #include

Look for board support:

damm@t400s ~/git/sh-2.6 $ grep SMSC911X_SWAP_FIFO
arch/sh/boards/mach-rsk/devices-rsk7203.c
       .flags          = SMSC911X_USE_32BIT | SMSC911X_SWAP_FIFO,

Look for driver support:

damm@t400s ~/git/sh-2.6 $ grep SMSC911X_SWAP_FIFO drivers/net/smsc911x.c
       if (pdata->config.flags & SMSC911X_SWAP_FIFO) {
       if (pdata->config.flags & SMSC911X_SWAP_FIFO) {
damm@t400s ~/git/sh-2.6 $

Sorry magnus, maybe I'm able to develop some pieces of kernel, but for sure i 
dont' know how to use the cooperative development tools; now I'm learing. 
Thanks for your patience

Thanks again
