Aug 29 16:38:37 <ulf_k_> im looking for the user G2, he helped me a few day ago at night in some jtag and flash problems / questions 
Aug 29 16:39:14 <ka6sox-office> haven't seen him today...he might be fairly busy with Weather now.
Aug 29 16:48:11 <ulf_k__> is he attacked by katrina
Aug 29 16:48:52 <ka6sox-office> maybe only peripherally...we hope.
Aug 29 16:58:01 <ulf_k__> where are you from?

Aug 29 20:16:55 <ulf_k> hello, i just compare the wrt54g version 1.0 with my dwl7000 from dlink, the flash chip is both amd 29lv320db!
Aug 29 20:16:58 <ulf_k> i killed my dwl-7000 , but now i can access this device via jtag
Aug 29 20:17:25 <ulf_k> but openjtag do not support 29lv320
Aug 29 22:54:33 <JerseyCow> moo
Aug 29 23:16:07 <ka6sox> morning
Aug 29 23:16:19 <ep1220> morning
Aug 29 23:17:01 <ka6sox> been swamped..what's new?
Aug 29 23:18:42 <ep1220> From my side:  trying to estimate what a FPAG JTAG solution will cost
Aug 29 23:18:49 <ep1220> s/FPAG/FPGA
Aug 29 23:18:53 <ka6sox> ah.
Aug 29 23:19:12 <ep1220> There are some "nasty" fixed costs
Aug 29 23:19:21 <ep1220> Like a USB vendos ID is 1500$
Aug 29 23:19:45 <ep1220> Or the compiler coming with the Cypress SDK only does 4K
Aug 29 23:19:57 <ep1220> Not enough.
Aug 29 23:20:11 <ep1220> The full version is 1500EUR (with a debugger 2500EUR)
Aug 29 23:20:36 <ka6sox> ouch
Aug 29 23:21:31 <ep1220> I found a cheaper dev System at 500EUR - it compiles the demos, but the produced code does not run :-)
Aug 29 23:21:52 <ka6sox> ugh
Aug 29 23:21:53 <ep1220> Seems Cypress uses some Keil specific features
Aug 29 23:22:59 <ka6sox> interesting.
Aug 29 23:23:29 <ep1220> in the readme they say it only works woth the Keil compiler :-(
Aug 29 23:23:54 <ep1220> well, maybe it is only a problem of the startup code.
Aug 29 23:23:55 <ka6sox> thats expensive!
Aug 29 23:24:15 <ep1220> Agree.
Aug 29 23:24:54 <ep1220> Then there are issues with new laws here in the EU regarding disposal of electronic waste.
Aug 29 23:25:40 <ep1220> I do not think it is possible to sell it as a build-it-yourself-kit.
Aug 29 23:26:59 <ka6sox> hmmm...maybe [g2] needs to look into it.
Aug 29 23:27:15 <ep1220> From this point, the FTDI comes a lot cheaper.
Aug 29 23:27:32 <ka6sox> the FTDI I like...
Aug 29 23:27:40 <ep1220> FTDI allows users of its chip to use the FTDI USB vendor ID
Aug 29 23:27:43 <ka6sox> I have a Dev kit.
Aug 29 23:27:50 <ep1220> And no compiler needed.
Aug 29 23:27:56 <ep1220> The DLP2232M ?
Aug 29 23:28:03 <ka6sox> yes
Aug 29 23:28:16 <ka6sox> I have 2 of them.
Aug 29 23:28:24 <ka6sox> and am sending one to dyoung
Aug 29 23:28:58 <ep1220> Do You have the module only ?
Aug 29 23:29:14 <ep1220> Or built some HW around so it is ready to use ?
Aug 29 23:30:01 <ep1220> I have built a JTAG IF around it. 3.3V only. Use it on the NSLU2.
Aug 29 23:30:43 <ka6sox> I have built some HW around it...for rebooting slugs and putting them into upgrade mode.
Aug 29 23:31:39 <ep1220>  prog the FLASH ?
Aug 29 23:31:54 <ka6sox> yes
Aug 29 23:32:08 <ep1220> What speed do You get ?
Aug 29 23:32:54 <ka6sox> wait..I'm using it to put he slug into upgrade mode for upslug..not flashing the jtag with it...yet
Aug 29 23:34:04 <ep1220> I am not familiar, what this procedure does. Clear some memory (?)
Aug 29 23:35:29 <ka6sox> it erases a portion of the memory and makes it ready to reflash the payload while leaving the bootloader alone.
Aug 29 23:36:33 <ep1220> Is this done using Redboot ?
Aug 29 23:37:09 <ka6sox> yes
Aug 29 23:37:33 <ep1220> So the FTDI then does serial to USB ?
Aug 29 23:39:19 <ka6sox> serial to usb as well as usb to parallel to talk to the uC that is on the device.
Aug 29 23:39:48 <ep1220> I see.
Aug 29 23:40:06 <ka6sox> I bought the one with the micro onboard.
Aug 29 23:40:36 <ka6sox> and have 3 channels of A/D as well as 10 remote control.
Aug 29 23:41:02 <ep1220> Ahh, ..  ;  I have the FTDI only module.
Aug 29 23:45:27 <ep1220> ka6sox: Can You access the built-in JTAG functionality with this module ?
Aug 29 23:45:47 <ka6sox> I have a carrier board that I've designed specifically for remote control.
Aug 29 23:45:56 <ka6sox> ep1220, I think so.
Aug 29 23:46:04 <ka6sox> but I'll have to check that.
Aug 29 23:47:23 <ep1220> Just sent You a PM with a link to the schematic of my HW
Aug 29 23:50:55 <ka6sox> the schematic is very good...and the pix are excellent.
Aug 29 23:51:45 <ka6sox> I think that with the Micro we could do some interesting things too.
Aug 29 23:51:59 <ka6sox> although strictly speaking its not necessary.
Aug 29 23:52:54 <ep1220> What is the cost of this module
Aug 29 23:53:48 <ka6sox> its $50US
Aug 29 23:53:57 <ka6sox> but it can be done cheaper.
Aug 29 23:54:08 <ka6sox> (they are building in a lot of profit)
Aug 29 23:55:50 <ep1220> Yeah, but there are fixed cost and it is uncertain how many modules one could sell.
Aug 29 23:56:08 <ka6sox> the board is the biggest fixed coset.
Aug 29 23:56:09 <ka6sox> er cost.
Aug 29 23:57:11 <ep1220> I did a PCB design for FTDI/3.3V and got me some quotes for manufacturing. At a run of 100 units I got a cost of close to 50$
Aug 29 23:58:02 <ep1220> Now add in cost for packaging, credit-card processing, financing, guarantees ..
Aug 29 23:59:56 <ka6sox> sounds right
Aug 30 00:01:50 <ep1220> Since doing this estimates (also the FPGA) I tend to feel the price of Abatron &Co to be less a ripp-off I thought originally :-)
Aug 30 00:02:10 <ka6sox> ooohyeah,.
Aug 30 00:03:58 <ep1220> another option would be to just make a PCB to extend the modules sold by FTDI (e.g the DLP 2232M) and sell the PCB only
Aug 30 00:05:04 <ep1220> The parts needed are all available at e.g. digikey
Aug 30 00:07:51 <ka6sox> the board that I designed was kinda specific but I could add some pads.
Aug 30 00:09:36 <ep1220> You could check if the JTAG pins are acessible on Your module.
Aug 30 00:09:55 <ka6sox> yes I should...tommorrow...its after midnight here.
Aug 30 00:10:12 <ka6sox> if so maybe we could talk more about what would be needed.
Aug 30 00:10:33 <ka6sox> I would need to add those pins to the board.
Aug 30 00:10:45 <ep1220> I'd be happy to do so.
Aug 30 00:10:50 <ka6sox> probably in the Digilent layout.
Aug 30 00:11:03 <ka6sox> 1x7 I think
Aug 30 00:11:09 <ka6sox> and mabye the 2X7 as well.
Aug 30 00:11:19 <ep1220> the digilent has no RESET and TRST
Aug 30 00:11:28 <ep1220> You need these for JTAG debugging.
Aug 30 00:12:43 <ep1220> Do You know the name of the module You use, out of Your head ?
Aug 30 00:13:44 <ka6sox> http://www.dlpdesign.com/usb/2232pb.shtml
Aug 30 00:15:13 <ep1220> Maybe I find the time to look at it during the course of the day
Aug 30 00:15:52 <ka6sox> thanks...I appreciate it.
Aug 30 00:15:55 <ka6sox> off to bed.
Aug 30 00:16:02 <ep1220> Good night
Aug 30 02:21:40 <JerseyCow> moo
