I'm seeing prices like $130 on ebay.  Is this the going price or should I
look elsewhere?

 

Just noticed that on one of the auction pages (for example # 261021017145)
they also use the term "USB AVR JTAGICE XPII" . XPII???

 

Digikey and Mouser price $399 ???? something wrong here ??

 

Another ebay auction refers to "MODEL: JTAGICE2 MKII CN . AVR studio
recognize it as JTAGICE MKII, fully compatible with original. And
UPGRADABLE."  . "recognize it as JTAGICE MKII" ???  Anyone use this device?

 

I'm getting nervous seeing things that appear JTAGICE Mk2 "like" .

You might just be seeing a price drop on the Mk2 because the current model is mk3.

Be nervous, be VERY nervous.

Atmel store http://store.atmel.com/SearchResult.aspx?q=gsd:c-100112_k-jtag
has it also for $399.00, at times they have specials.

The new JTAG Mk3 is only $99.00 but ONLY works with the horrendous AS6.

I got my JTAGICE Mk2 from someone on AVRFreaks for about $200.00 a 
few years ago,
at times people sell these cheaply on the Trading Post forum as they 
want to keep
up with the latest or no longer want to use AVRs.

Maybe you could post there as a "wanted" item, you never know.

AS6?  Bloated, yes, but horrendous, no.  I've had no problems programming
and debugging Xmega128A1's with my JTAG Mk3 with AS6.  

 

Using AS6 and the Mk3 was initiated by the fact that I fried my JTAG Mk2 and
I decided to give AS6/Mk3 a chance, particularly because at the time
replacing the Mk2 would have been considerably more expensive.  Apart from
cursing the AS6 learning curve for a while, I'm glad I made the jump and
have no regrets.

Perhaps that is why the mkII price seems to be peaking. IIRC I paid $150 a few years ago from Arrow for my mkII.

I suspect that most MkIIs will have to have a software upgrade if you run it from Studio6. This happens pretty transparently, after you give permission, but it may catch you by surprise if you are not aware of it.

Good choice Chuck,

 

I have had my JTAG ICE Mk2 for about 8+ years now and it is bullet proof. I
have done silly things with wrong wiring and still it works.

 

Far more sturdy interface than the Dragon so a good choice for the serious
developer.

I managed to fry my Mk2.  It's been a while but IIRC it was something to do
with the reset line, some voltage got on it that should have known better.

I did the same but just replaced the transorb chip behind the ribbon
cable header and it came back to life.

I had to Mk2s and loaned one to a client and he says its partially fried now.  Until I get it back I won't know what that means.  I'm not sure what he did to cook it, but he says he can set fuses with it but needs to use his Dragon to program parts.

Off the top of my head if your virgin parts do not come with JTAG enabled you must have an ISP or parallel programmer (Dragon comes to mind as having all 3) to initially set the JTAG fuse appropriately.

Think an ISP is only $30.

He had a dragon, and had some boards that a previous person had put into debug mode so he couldn't program them.  He couldn't turn off the DWEN fuse with his Dragon so I loaned him my mk2, which he used for a while.  Then he told me he could set fuses with the MK2, but not program and program with the Dragon but not set fuses.

I suggested that he only use an ISP so that his employees don't have the ability to make as many mistakes when they burn the parts but he wants to stick with the Dragon for now until he ramps up production.

They do.  I am a big, big fan of JTAG and I've never had to enable it before using it.

Am pretty sure the ATmega64 I was using in 2006 did not come with JTAG enabled. I know I had to put both JTAG and ISP ports on my board.

First, let me say I'm only continuing this side-thread so that people listening in know the truth, not because I'm in the mood for an argument or anything like that.  I don't think it's a big deal.  I just happen to really, really, know the facts here.

In 2006, I didn't own a programmer other than my AVR ICE-Cube, which is JTAG only.  I worked with the ATmega64.  Therefore, they came from the factory with JTAG enabled.

The ATmega64 data sheet, Atmel document 2490Q–AVR–06/10, says "To be able to use the JTAG interface, the JTAGEN Fuse must be programmed. The device is default shipped with the fuse programmed".  OK, grammar not so great, but you know what they mean.

Now I own an AVR Dragon, JTAGICE MkII and JTAGICE MkIII.  Even so, if the device I am using has JTAG, I invariably use it.  I am that into JTAG.  I have never, ever, had to enable JTAG.  It is always enabled as the device comes out of the packet.

David, whatever is "off the top of your head" or you are "pretty sure" about, I am 100%, hand-on-heart, put-money-on-it positive that JTAG is enabled by default and nobody needs to have other programming interfaces if they want to use JTAG.

Graham.

Full Disclosure - I am on the verge of breaking my rule with the ATxmega192A3 and using the PDI interface instead of JTAG for production programming (not development) simply because I don't have the space for the 10-pin JTAG header.

JTAG only uses 6 pins (Vcc, Gnd, TCK, TMS, TDI, TDO).  An alternative would be to use a 6-pin header and/or a finer pitch header and then make an adapter cable from that to the standard 10-pin 0.100" pitch JTAG connector.

Actually, that may be true.  I currently have the JTAGICE MkII connected to a device using only the six pins I mentioned.  That is sufficient for JTAG debugging but it may not be sufficient for programming.

Either way, using a finer pitch header and an adapter may solve the space issue.

Yes, I believe that is correct, RESET is not needed for debugging, only

To save board space and maybe a few pennies on the connector, I've seen something called Tag Connect.  This is a 6 pin pogo connector that attaches onto the board and makes contact with the traces.  That might also solve the space problem.  When I used it on a PIC based project it worked well.

Don,

Your point is well taken.  The standard 10-pin JTAG connector has two grounds, both power for the interface device and target power sense and an unused pin.  So, only seven are actually necessary: the four JTAG signals, ground, target power sense and reset.  Using an adapter of some sort, it is always possible to reduce the physical size of the connector and I have used 0.05 inch pitch, single-row headers for exactly this purpose.  Plus, you can stick a single-row header in a row of holes, press it to one side and get pretty good contact.

There's still the issue that PDI requires only four pins.  The local Atmel applications engineer says that the only reason to use JTAG in preference to PDI on the ATxmega family is chaining.  I could justify being in a rut using only JTAG when it had clear advantages over the alternatives, i.e. ISP (screw up the fuses and you're in trouble) and debugWIRE (slow and awkward).  I don't need chaining, so if PDI is as good as JTAG (and, so far, it seems to be) I should get over my love of JTAG and use PDI.

Nothing is cast in stone yet.  Actually, I'm having trouble with the battery charger - my MAX1873 won't do what the data sheet says it should do.

Graham.
