First off I am new to JTAG emulation. I am required to program a Xilinx configuration PROM from a microcontroller. I realize that I can program the PROM with a cable from the parallel port but the product will require field upgrades. I've been sifting through docs from Xilinx and searching the web, and it seems like this should be easy and straight forward to implement. What I have learn...

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...

i'm a newbie in Embedded world. I need some clarification about the arm gdb debugging. 1. Is there any options to debug the board through serial port ? how? 2. All search results about the arm debugging are related with some kind of external hardware and JTAG why? 3. I found results about gdb stubs for some non arm architecture. is there any stub for arm without a external hardware or JTAG...

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...

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. Something like macraigor OCDRemote but for this processor. greetings Carsten -- http://learn.to/quote - richtig zitieren http://www.realname-diskussion.info - Realnames sind keine Pflicht http://oe-faq.de/ - http://www.oe-tools.de.v...

Hi! Does anyone know of a tool that will generate svf files (or something simillar) for ARM cortex based micro's. I've actually got an STM32 but which flavour of cortex shouldn't matter. This is the means by which a production JTAG interconnection tester (JTAG technologies in this instance) programs CPLDs, micro's or other simillar stuff. At the moment we are just using an open source co...

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...

For an existing motor control application, we're considering upgrading from our current ROMless ST10R167 processor to newer one with onboard flash to get faster execution. One of the main attractions of the Infineon XC16X chips is JTAG debugging, with excellent code and onboard peripheral compatibility with the C167/ST10. (Using a bond-out emulator isn't practical with our equipment.) We use ...

Hello, has anybody hard facts what the requirements for the ration between Jtag/SWD clock and MCU clock is. Main interest is for Cortex-M, but facts for other archs are welcome. Information floating aound in the net tells abound a factor of 6, but some people tell about successfull SWD communication even with a MCU clock much slower than the SWD clock. Thanks -- Uwe Bonnes ...

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: I have recently begun using an EzDSP board from Spectrum Digital for the TMS320F2812. On the board is a FPGA implementing an embedded JTAG emulation port, which talks to the PC via a parallel printer port. I am thinking it is possible to use this board as a JTAG emulator for a TMS320F2812 chip on *any* board, such as one I design myself. That way, I could have general purpose J...

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. ...

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...

Hi all... I have following problem. When I wanted to debug my project written in IAR 4.2 using Olimex's JTAG ISO, a message popped up saying something like Olimex firmware version is not supported and it offered me to update firmware. I said no, but I could not download my project. I tryed again but this time I said yes when he asked for firmware update. After that I still can not download my pro...

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...

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
