**** BEGIN LOGGING AT Sat Jul 02 23:59:56 2005 Jul 03 04:28:15 What is the current development status of JTAG adapter hardware? Jul 03 08:38:21 What is the current development status of JTAG adapter hardware? Jul 03 08:56:54 The hardware is pretty much standardised on the Spartan 3 devboard. Progress is a bit slow at the moment because all the developers are busy with other projects. Jul 03 09:00:35 is ep working on it? Jul 03 09:03:31 Don't know. Why? Jul 03 09:04:54 I'm interested in the details Jul 03 09:06:41 Okay. There are two choices for platform at the moment. A FPGA or a FTDI USB dongle Jul 03 09:07:07 yup Jul 03 09:07:17 The FPGA being more powerful but also harder for other people to develop on since it requires knowledge of VHDL Jul 03 09:07:40 The USB one being easier since most of it will be running on the host PC Jul 03 09:07:50 And I gathered that work is being done on the FPGA Jul 03 09:07:59 We're investigating both Jul 03 09:08:50 However, as I said earlier we're all pretty busy. Most of us are also on the NSLU2-Linux project and that is requiring a lot of time at the moment Jul 03 09:31:05 Hm, I have a problem with the openjtag wiki Jul 03 09:31:17 do I always need \\ for a line break? Jul 03 09:31:34 without, all the lines are concatenated Jul 03 09:31:45 that seems stupid Jul 03 09:32:07 That's normal Jul 03 09:32:19 Put it into paragraphs with a line in between if you don't want that Jul 03 09:34:00 but then I get paragraphs Jul 03 09:34:55 You have to put the \\'s in otherwise it thinks you want paragraphs Jul 03 09:35:15 It's the same way HTML works for formatting except it uses \\ instead of
Jul 03 09:35:33 is it the mediawiki engine? Jul 03 09:35:39 No. pmwiki Jul 03 09:35:52 oh, I was used to mediawiki Jul 03 09:40:23 Does the wiki allow hierarchical grouping like 1.1, 1.2, 1.2.1, 1.3 etc.? Jul 03 09:40:44 It doesn't handle sections. You can do numbered lists if you wish but that's it Jul 03 10:12:45 OK, I updated the wiki to reflect the options that were being evaluated. Jul 03 10:17:02 Thanks. Are you interesting in the debugging aspect or the flash rewriting part? Jul 03 10:18:02 More in the debugging, but it goes hand in hand IMHO Jul 03 10:18:32 k. Just wondering. Some people just want to be able to reflash stuff quickly since the only free or very low cost adapters out there are incredibly slow Jul 03 10:18:34 I have my own JTAG library, but I'm missing hardware, so I'm most interested in hardware! Jul 03 10:18:45 100 bytes per second for a parallel port dongle doing a XScale Jul 03 10:18:47 Oh? Jul 03 10:20:50 I wanted to help making the FPGA core, but I don't have a PC right now, and I can't run the synthesis tools on my Mac :) Jul 03 10:23:27 VirtualPC? :) Jul 03 10:23:47 qemu, it is SLOOOW Jul 03 10:24:44 We're not supporting the Linux tools at the moment. Last time one of us tried it, the bitstream generated was really wacky Jul 03 10:25:13 It was wrong and totally different to what the Windows tools synthesized Jul 03 10:25:36 argh :) We love xilinx Jul 03 10:26:16 It *may* be better now. We've not tested it. I hope it's better anyway... Jul 03 10:26:28 The last time it was tested, the Linux tools were still non free Jul 03 10:27:03 the WebPack? Jul 03 10:28:39 Yeah. They didn't have that then for Linux Jul 03 10:29:00 but that was a LONG time ago Jul 03 10:29:16 Yep Jul 03 10:29:30 As I said, hopefully it works now :) Jul 03 14:32:58 hey g2 Jul 03 14:34:04 <[g2]> JMunakra, howdy! Jul 03 14:34:15 I updated the wiki :) Jul 03 14:34:34 I added some initial text on the JTAG hardware being discussed Jul 03 14:34:42 but that info is 2 months old Jul 03 14:34:56 so if there's news to that.... have a look and tell me Jul 03 14:35:24 <[g2]> ep1220 has made great progress with the FTDI and then NSLU2 Jul 03 14:35:34 <[g2]> FTDI chip hooked up to the NSLU2 Jul 03 14:35:51 Is he using the EZNIOSUSB? Jul 03 14:36:05 <[g2]> he's been able to JTAG load directly into the mini-I cache and execute code Jul 03 14:36:18 <[g2]> No I think it's just a chip on a eval board Jul 03 14:36:34 is there a link for it Jul 03 14:38:17 <[g2]> check with ep1220 Jul 03 14:38:40 <[g2]> He'll be moving on the the Spartan3 FPGA implementation in a little while Jul 03 14:38:57 <[g2]> but he's verfied that the JTAG is working with the FTDI eval board Jul 03 14:39:30 sounds good Jul 03 14:39:35 is the code in CVS? Jul 03 14:41:03 <[g2]> I don't think so Jul 03 14:41:13 <[g2]> I don't know what ep1220's plans are for it Jul 03 14:41:22 <[g2]> but that's a good question Jul 03 14:41:57 I'd like to have a look at it for sure :) Jul 03 14:42:30 <[g2]> last week we resolved the mystery about whether the nslu2 runs at 133 or 266 Jul 03 14:42:50 and? Jul 03 14:43:15 It's brilliant : Jul 03 14:43:17 :D Jul 03 14:43:36 <[g2]> it runs at 133 but .... http://www.nslu2-linux.org/wiki/HowTo/OverClockTheSlug Jul 03 14:43:39 [g2] :) Jul 03 14:44:03 <[g2]> NAiL, what's brilliant ? Jul 03 14:44:19 the mod :) Jul 03 14:44:28 <[g2]> yes. Jul 03 14:44:40 It'll get warm. Jul 03 14:44:56 <[g2]> JMunakra, what will get warm ? Jul 03 14:45:03 just reading Jul 03 14:45:24 * [g2] thinks it spoke before reading the full wiki page :) Jul 03 14:45:42 <[g2]> DOH! sorry s/it/he/ Jul 03 14:45:46 haha Jul 03 14:45:55 <[g2]> that's *not* funny :( Jul 03 14:46:19 so you have the xscale docs, and they didn't document those pins? Jul 03 14:46:50 [g2]: sry Jul 03 14:47:33 <[g2]> Linksys uses an undocumented feature do under clock the device to 1/2 it's lowest speed grade which is 266 Jul 03 14:48:04 what crystal freq do they have? Jul 03 14:49:00 <[g2]> 33 Jul 03 14:49:40 hm, so they have a couple of DLLs in there, and can skip one Jul 03 14:52:08 <[g2]> DPLL ? Jul 03 14:53:42 DLL = delay locked loop Jul 03 14:54:23 <[g2]> ok... I'm not sure about DLL Jul 03 14:54:44 <[g2]> I know about Phase locked loops and Digital Phase Locked loops Jul 03 14:54:47 me neither, but that's what FPGAs use to double clocks Jul 03 14:55:06 <[g2]> it think we're saying the same thing Jul 03 14:55:19 there must me a slight diferrence though Jul 03 20:02:39 I think that the NAiL Clippers should be the official mod. Jul 03 20:02:54 requires no solder. Jul 03 20:22:35 hehe Jul 03 20:28:46 "Add Serial Line LCD display to get status" Jul 03 20:28:56 Somebody added that to the UsesForRxOnlySerialPort page Jul 03 20:29:14 hellooo.... receive only.... Jul 03 20:30:16 Reminds me of a trouble ticket when I worked for a big company..the "computer" help desk started writing tickets for 2-way radio problems. Jul 03 20:30:41 1 day the techs got the following description of trouble: "Receiver doesn't Transmit" Jul 03 20:31:14 the ticket was closed with a notation.... Jul 03 20:31:23 heh Jul 03 20:31:58 PEBCAK! Jul 03 20:32:19 this google maps thing is addictive Jul 03 20:32:28 especially satellite imagery Jul 03 20:32:47 with this a Cruise missle could even find me! Jul 03 20:32:47 (scary) Jul 03 20:33:22 well. if you had a missile lying around then chances are you have access to the satellite imagery anyway Jul 03 20:33:32 latest satellites apparently are sub 1m resolution Jul 03 20:35:29 but finally I have a true picture of the surrounding countryside and exactly why we can't get any service 30km away. Jul 03 20:35:29 this isn't that good...(thank God) Jul 03 20:36:30 interesting...ooo problem...weird. Jul 03 20:36:36 ? Jul 03 20:37:39 out of order Jul 03 20:38:40 huh? Jul 03 20:40:35 this isn't that good (thank God) was delivered after the other one...even though it was typed first Jul 03 20:41:09 ah Jul 03 20:41:55 something the size of Ben Nevis in the way **** ENDING LOGGING AT Sun Jul 03 23:59:56 2005
