Hi. The programming interface changed from ISP to PDI on XMega controllers. The JTAG MKII can program and debug the XMegas via PDI with a software update, but only the newer hardware revisions seem to have the required hardware support. I'm not very happy to discard my current hardware and spend 300? for another one. So my question is: What are the hardware differences between the o...

Hi I'm using a 80C51F302 Cygnal device and I have based the design on what I've read on the Cygnal site that C2 is the way to go for such a pin-limited device. Well in the forum on the site some have commented that the JTAG interface is vulnerable to noise and 4k7 pull-up/down are recommended. But using a low-power device and putting load resistors on the signals seems futile to me. If...

Hi, Why powerpc debug tools are so expensive? Does anybody know low-cost USB powerpc jtag/cop ? Amontec website mentions about USB version of Chameleon POD but no informayion for now. Macraigor cheapest usb hardware is $225 + they sell their flash programming software for $500. Any chance to find some open hardware-software combination? thanks

Hi I decided to choose LPC21xx ARM devices as my microcontroller for small applications. I still havent found out what the cheapest and easiest way is to develop and debug. Are there any free or low cost solutions that allow jtag graphical debugging (win or linux ) ? Is there a low cost alternative to keil-ARM tools ? (The Keil Ulink Jtag and their LPC21xx based boards look a good s...

I have a straight out of the box Olimex Arm-7 board, plugged into a just purchased Segger J-link JTAG adaptor. On powering up, the host software can't detect the target, the LED on the JTAG modules is orange. I posted this on the Segger forum, and the advice was that the Olimex board was in reset. I then posted this back on the Olimex forum and have not received any responses in a week. ...

Hello all, is it possible to debug a Motorola MC 68040 via JTAG? I'm looking for a cheap way to debug software in MC 68040 via PC. gdb would be perfect.

Howdy, I have a PowerPC 405GP Walnut eval board. Recently, by accident, the flash which stores U-Boot is corrupted. Therefore the board cannot boot now. I want to use the JTAG port on the board to rewrite the flash with new U-Boot. I found many products for this propers, but they are too expensive for me. It costs $1000-$3000... > _ < Eg: BDI2000, Silicon Probe... What I really want is

Has anyone successfully used this product (AVR-USB-JTAG from Olimex)? I posted a query here a week or two ago, no replies - so I ordered one from Spark Fun Electronics. It arrived with the wrong USB cable (they shipped A to B, it requires A to A) and SFE never responded to my email asking for the problem to be corrected (note to self: buy elsewhere next time).

I'm using an ST ARM Cortex part for the first time. I've been using Luminary parts until now. I notice that on the Olimex demo board for the STM32F103RBT6, they have the JTAG TRST pin connected, but on the Luminary eval board for the LM3S811 the TRST pin is left open. Does anyone know why this is? Is it just that the TRST pin is sorta optional, and the Luminary folks weren't in a m...

Q: I want a simple cost effective JTAG solution for programming a image to flash connected to a i386EX. I have checked the web and it seemes that most flash programmers do not support the x86. Is that right? We have an old solution based on an old APP note from Intel : http://www.intel.com/design/intarch/applnots/272753.htm Our main problem is speed! It seemes that writing to the paral...

Hello, I am designing a board with IBM PPC 405EP and TI DSP TMS320C6711C. I want put those devices in a single JTAG chain so that i can carry out boundary scan as well do the emulation by having jumpers appropriately. But i have one problem with defining a initial state for nTRST signal. In DSP it is pulled low internally and datasheet specifies not to put a pull-up on this line. But PP...

Hi all, We have already developed a flash programmer using a wiggler compatible JTAG interface, directly manipulating the JTAG pins (TCK, TDI, TDO, TMS) through the parallel port. We would like to speed up the process using a Raven compatible interface (actually we have a Chameleon POD). We haven't found any documentation about the interface of this device with a parallel port. Per...
