Jan 27 07:31:56 <vmaster> hmm... how difficult is it to get a jtag header onto a nslu2?
Jan 27 07:35:49 <dyoung-away> vmaster: http://nslu2-linux.thestuffguy.com/gallery/jtag
Jan 27 07:36:03 <vmaster> thanks
Jan 27 09:08:40 <ka6sox> velinp, any word on your fattened Slug?
Jan 27 09:10:20 <velinp> ka6sox: not fattened; friend hesitating about risk/benefit; maybe later (found a local supplier of 256Mbit chips, price ~12 EUR; need some soldering hardware update, etc.) 
Jan 27 09:11:13 <ka6sox> velinp, its not easy with those small traces.
Jan 27 09:12:52 <velinp> yes, i know :) friend has experience; i trust him when he says 'it;s risky'; how are bob and wendy doing? velnas is stuck with mingw32 for >60 hours;
Jan 27 09:13:18 <ka6sox> they are both chugging away...
Jan 27 09:14:32 <ka6sox> I'm still working on getting fatter hardware to reduce the swapping
Jan 27 11:04:43 <prpplague> http://www.goepel.com/content/html_en/index.php
Jan 27 11:04:48 <prpplague> anyone looked at these guys
Jan 27 11:04:56 <prpplague> they are covered in the latest circuit cellar
Jan 27 12:35:59 <prpplague> beewoolie: hey hey
Jan 27 12:36:05 <beewoolie> prpplague: 
Jan 27 12:36:08 <beewoolie> prpplague: hi
Jan 27 12:36:48 <beewoolie> The good news is that I understand what I have to do to perform accelerated debugging on the Xscale.
Jan 27 12:37:07 <beewoolie> The bad news is that I don't have a jtag emulator with the necessary signals.
Jan 27 12:38:23 <ka6sox-office> beewoolie, bummer
Jan 27 12:38:29 <ka6sox-office> *soon* (tm)
Jan 27 12:38:32 <beewoolie> A minor setback.
Jan 27 12:38:53 <beewoolie> The dongle from GW may have the nSRST signal.
Jan 27 12:39:08 <beewoolie> It turns out that there isn't really a substitute on this CPU.
Jan 27 12:40:54 <beewoolie> [g2]: Any word on the GW docs?
Jan 27 12:43:09 <[g2]> beewoolie I got them last night.  However, all the pages said "..... Confidential"  across them....  
Jan 27 12:43:10 * [g2] was not pleased
Jan 27 12:43:30 <beewoolie> OK.  Let me know if/when they are willing to share.
Jan 27 12:48:00 <[g2]> beewoolie I'm sure I could send you a copy as I don't think you release the docs to the world
Jan 27 12:48:17 <[g2]> However, I wound not want the software you write to be restricted
Jan 27 12:48:25 <beewoolie> [g2]: How would they feel about an OSS driver... yeah.
Jan 27 12:48:52 <beewoolie> As long as it only works with their device, is there really an issue?
Jan 27 12:48:55 <[g2]> We may be better off putting our energies into a different platform
Jan 27 12:49:03 <beewoolie> Fair enough.
Jan 27 12:49:17 <beewoolie> I was hoping for something in the short term that supports sRST.
Jan 27 12:49:32 <beewoolie> I need it for Xscale.
Jan 27 12:49:52 <beewoolie> I may have to start with the ep1220 board instead.
Jan 27 12:50:02 <[g2]> it may well be that for the short-term (next few months) we use this
Jan 27 12:50:31 <[g2]> I'm not sure
Jan 27 12:50:45 <beewoolie> Does their SW work from Linux?
Jan 27 12:50:46 <[g2]> I wanted to cool off a little before I speak with them about it
Jan 27 12:50:56 <beewoolie> Are you mad?
Jan 27 12:51:20 <[g2]> I'm not mad, I'm a tiny bit disappointed
Jan 27 12:51:20 <beewoolie> Or has the weather been unseasonably toasty?
Jan 27 12:51:24 <beewoolie> Hmm.
Jan 27 12:51:58 <beewoolie> I'm glad to return it if this doesn't work out.
Jan 27 12:54:42 <[g2]> nod
Jan 27 12:54:44 <[g2]> thx
Jan 27 16:46:36 <vmaster> [g2]: still there?
Jan 27 17:02:12 <vmaster> beewoolie: if you're looking for something cheap that's known to work, have a look at the olimex arm-jtag (sparkfun distributes to the u.s., iirc) - it's a simple parport wiggler clone, with working nSRST
Jan 27 17:02:29 <beewoolie> vmaster: Cool.
Jan 27 17:02:34 * beewoolie browses...
Jan 27 17:10:22 <beewoolie> vmaster: $20.  Not a lot of corn.
Jan 27 17:11:33 <vmaster> i doubt any commercial offering could be a lot less
Jan 27 17:11:51 <beewoolie> Indeed.
Jan 27 17:12:22 <vmaster> i have one on my desk, and i know that i'm able to control both nTRST and nSRST separately
Jan 27 17:13:06 <vmaster> which is what you need for xscale debugging - you hold the core in reset while loading the mini i-cache
Jan 27 17:13:16 <beewoolie> That's exactly the issue.
Jan 27 17:15:52 <beewoolie> Oddly, they don't have a schematic for the arm-jtag.  There is one for the MSP  hip
Jan 27 17:17:11 <vmaster> there's a posting in the sparkfun forum from olimex documenting the arm-jtag connections
Jan 27 17:18:09 <beewoolie> do you have a link?
Jan 27 17:18:31 <vmaster> http://www.sparkfun.com/cgi-bin/phpbb/viewtopic.php?t=2068&highlight=armjtag
Jan 27 17:19:14 <vmaster> there are typos, DB is always DB25, not DB26, but the signals are correct
Jan 27 17:19:42 <vmaster> and NTRST is really nSRST, TRST is nTRST
Jan 27 17:20:20 <beewoolie> That can be deduced from the JTAG pin numbers.  Looks good.
Jan 27 17:20:42 <beewoolie> Someone just pointed me to a device called jlink.
Jan 27 17:20:47 <beewoolie> I'm going to check that out, too.
Jan 27 17:20:47 <vmaster> segger
Jan 27 17:20:56 <vmaster> it's proprietary withouting documentation
Jan 27 17:21:03 <beewoolie> Not good.
Jan 27 17:21:46 <beewoolie> Is it the ftdi2322?
Jan 27 17:22:20 <vmaster> I don't think so, as it's faster than the FT2232 ever could be
Jan 27 17:22:47 <beewoolie> Looks like it's windows centric?
Jan 27 17:22:55 <vmaster> yes
Jan 27 17:23:02 <beewoolie> Non starter
Jan 27 17:23:43 <beewoolie> Probably not $20.
Jan 27 17:24:26 <vmaster> it's reliable debugging hardware, if you're willing to pay the price
Jan 27 17:25:01 <beewoolie> I bought a bdi2000 for that reason.  It's reliable, but not flexible.  Can't use it for xscale unless I want to pony up another US$1000
Jan 27 17:25:18 <beewoolie> And since I don't get paid for the Xscale work, that's not happening.
Jan 27 17:27:44 <vmaster> i'm looking to get an xscale development board, as it's always been on my wish-list for the openocd
Jan 27 17:28:33 <vmaster> but xscale debugging is a whole new world - most of what i've done one the host for arm7/9 targets has to happen on the xscale
Jan 27 17:38:05 <vmaster> I'm off - night everyone
Jan 27 17:38:36 <lennert> vmaster: nite
Jan 27 17:47:25 <[g2]> vmaster nite
Jan 27 17:47:35 <[g2]> I'll catch you tomorrow
Jan 27 17:48:14 <[g2]> lennert beewoolie can I ask you a quick question ?
Jan 27 17:48:27 <beewoolie> as long as I can ask you one.  :-)
Jan 27 17:49:37 <[g2]> sure I've got to run in a couple minutes but can ask now
Jan 27 17:51:24 <[g2-lap]> http://pastebin.ca/38858
Jan 27 17:51:46 <[g2-lap]> The madwifi driver is oopsing on an address that seems valid
Jan 27 17:52:08 <[g2-lap]> The PCI space is mapped as a 64K region at 0x48000000
Jan 27 17:52:24 <[g2-lap]> and the address being referenced is 0x48004004
Jan 27 17:54:26 <[g2]> beewoolie what's your Q ?
Jan 27 17:54:38 <beewoolie> hang on, I'm reading your Q
Jan 27 17:55:55 <beewoolie> It could be that those addresses are PCI mapped and that it only goes for 0x4000 bytes
Jan 27 17:56:08 <beewoolie> An lspci would tell you.
Jan 27 17:56:45 <beewoolie> That would be my guess.
Jan 27 17:56:49 <beewoolie> The error is bonafide
Jan 27 17:56:58 <beewoolie> It is saying that the descriptor at that address is zero.
Jan 27 17:57:39 <beewoolie> Oh.  I see.
Jan 27 17:57:41 <beewoolie> You have that.
Jan 27 17:58:33 <beewoolie> Also remember that the memory reported by PCI is physical.
Jan 27 17:58:47 <beewoolie> The read is a virtual address read.
Jan 27 17:58:57 <beewoolie> There isn't a guarantee that they'll be identity mapped.
Jan 27 17:59:07 <beewoolie> Usually, they aren't, but I'm not so familiar with PCI.
Jan 27 18:00:09 <beewoolie> My question is easier.
Jan 27 18:00:25 <beewoolie> I haven't been able to find Harvold's router distro.
Jan 27 18:00:31 <beewoolie> Do you have a keyword or a link?
Jan 27 18:08:06 <[g2-lap]> https://svn.gnumonks.org/trunk/grouter/
Jan 27 18:08:14 <[g2]> beewoolie how's that ? :)
Jan 27 18:08:24 <beewoolie> sweet
Jan 27 18:08:51 <beewoolie> googling grouter got a lot of tile stuff
Jan 27 18:09:07 <[g2-lap]> http://gnumonks.org/~laforge/weblog/2005/
Jan 27 18:09:16 <[g2-lap]> search that page for grouter / linwrap
Jan 27 18:09:26 <[g2-lap]> bbl
Jan 27 18:12:42 <beewoolie> thanks
Jan 27 18:12:59 <[g2]> np
Jan 27 18:13:09 <beewoolie> He says that it is x86 only.
Jan 27 19:34:36 <[g2-lap]> re
Jan 27 19:35:44 <[g2-lap]> beewoolie I think we'd be able to take those apps and the configs and run them pretty easily
Jan 28 01:05:11 <beewoolie> vmaster_: I'm looking at the LH 79520 datasheet again to see how I missed the fact that it's an r3 part.  
Jan 28 01:05:18 <beewoolie> The file I'm looking at: http://document.sharpsma.com/files/tec_datasheet_lh79520.pdf
Jan 28 01:05:31 <beewoolie> If it says r3, it's well hidden.  Is there something else you were reading?
Jan 28 01:06:52 <beewoolie> Ah, now I see.  It's burried in the description.
