Hi All, I have to convert Intel Hex Code into JTAG bits so that I can directly provide the output (JTAG Bits) to the JTAG I/F. I can use JTAG for this. So can please let me know hoe to do Intel Hex conversion into JTAG bits. Any kind of example, documents and flow diagram will be highly appreciated. Thanks, Appu

Hi, I am writing a bit of software to control a JTAG port, but I am having a bit of trouble getting it working. Below are the steps my software is following to test out a JTAG connection. I think that there must be an error in there somewhere, but from my understanding of the JTAG TAP and the way JTAG works, I can't see a problem at the moment. Can anyone comment on whether I am cont...

Hi, it appears funny but interesting. I am debugging a problem and for which I am using TRACE32 JTAG interface on ARM platform. But when I try to run system without attaching JTAG it crashing where as at the same time once i mount it on JTAG it runs smoothly I observed that JTAG introduces some delay so i introduced some delays at specific locations but still it is same ... Anybody ca...

I'm new to learning about jtag and it's capabilities, and my professor isn't helping me at all. I understand jtag is mainly used in processors, but I was reading on Altera's website about a flash chip (EPM3032A) they use that has jtag support. What jtag device would I need to communicate with a flash chip like that? I understand there are jtag devices that support many versions of arm, mip...

Does anybody know if either the MSP430 or Atmel ATmega AVR parts (or associated JTAG interface widgets/SW) have problems when there are other devices in the JTAG chain? In the past, I've run into buggy JTAG stuff that couldn't tolerate having multiple devices in the JTAG chain. I'm working on a design with both an AVR and an MSP430, and I'd like to have a single JTAG header/chain. Before...

My JTAG Cable1 has just failed and I need to get another JTAG programmer, ideally with a USB interface although if it has to be serial so be it. Obviously I'd get an Atmel JTAG ICE Mk11 if the cost wasn't so ridiculously high so it'll have to be an alternative. What are people's views on the best one available at the moment? Thanks. Roger.

How can I use JTAG mode without ETM port on Philips LPC 210x? I pull up DBGSEL and RTCK during RESET, processor starts using jtag but also ETM port is enabled (I can`t use ETM pins as GPIO). I am also using LPC 212x - it is posible to turn on jtag without ETM port. Thank You

I have a jtag programmer for xilinx devices ,is this a standard interface ? Can i use this device to program other devices with a JTAG interface (eg ARM ) ? Or do i need a dedicated tjag interface for every Jtag device i intend to use ? (whats the use of a JTAG standard then ?) Johan

I have a microprocess device I would like to patch. It has some headers and I know one of them is JTAG, but I can't figure out which nor which pins have which JTAG lines (TRST, etc). Does anybody have some suggestions re. how to identify the JTAG pins, perhaps using a scope and a multimeter?

Hello everybody. I'm interested in developing a JTAG system using a FPGA programmed in VHDL. Is there some good source on line that can help me in doing that? Where can I found the specification of JTAG standard? Are they free available?

I am having problem jtag an ARM Cortex M3 at more than 1/256 of the system clock (6Mz). If I clock it any faster, the chip reports data overrun error. Is there any solution to speed it up? I can jtag an AVR at full speed, so I don't think it's a jtag problem.

Hi, I am working on ARM 922t, when I am trying to debug a small code say "hello world", I am getting Invalid CPU Mode debugger error upon doing single step debugging , I am using H-JTAG RDI interface. I have few Queries too.., (a) The customized board which I am using says to use MULTI ICE JTAG , but I am using winggler JTAG interface with H-JTAG RDI server!, can this create a problem? ...

Greetings, I am new to JTAG and and I am working on a project that that has an Atmel AVR. I want to be able to use JTAG but have not bought any programming/debugging devices yet. I would like to get something that is compatible with other products that I see myself using in the future such as FPGAs or other microcontroller families. I am on a tight budget and I want to get something tha...

I have several ARM evaluation boards, and they all have exceedingly similar pinouts on the JTAG port, varying only in how they treat TRST. Is there a standard out there on what the JTAG port should look like? If so, who maintains it? Is it available on the web? I'm kinda hoping for "yes", "ARM", and "here you go", but I'll take what I can get. -- My liberal friends think I'm a c...

Does anyone know of any software, ideally freeware, which can use the above JTAG interfaces to exercise other JTAG interfaces on non FPGA devices? In my case I'd like to read the state of pins on an unrelated device.

Hi all , I am new to AVRs and am designing circuit for a board. My question for ppl experienced with AVR and JTAG ICE mkII are - 1) Can JTAG ICE mk II be used for emulation as well as In-Circuit programming ? 2) Are there any special considerations for circuitry of the target board to use JTAG ICE mkII for both ISP and Emulation?
