I am trying to port the JTAG library released with TI App. Note 149 for use with my parallel port. I am able to reset the device and perform basic initialization over JTAG. However, I am having problems with writing to on-chip RAM. It turns out that whenever I write to a location, the location last accessed (read or write) gets corrupted. Here's an output showing what I mean: -------------...

Hi. I designed an ARM7 board with LPC2478 MCU. Unfortunately, JTAG doesn't work like one would expect. I can download code to FLASH, I can start debugging, BUT every time it comes to the first STR instruction I get "Could not stop device" ERROR. When I don't step the code it goes to some garbage address. I have ONLY ONE physical pull-up/down resistor on my JTAG 2x10 connector (device is...

Hi, I'm using an ARM-JTAG dongle interface (which uses parallel port, and is Macraigor Wiggler compatible) to program a TMS470R1A256 on a TMS470-P256 board (made by Olimex). I have been able to load the application to RAM and to flash, but when executed from flash, the applicaton runs 16 times slowlier. Using the debugging feature of the ARM-JTAG, I have stopped the execution in both cases...

What is commonly used for JTAG level shifting? I have an application where I need to convert a small number of signals from low-voltage TTL levels to "normal" TTL levels. It's very similar to a JTAG port where you have signals going in both directions and a reference signal indicating what the logic levels are. Modern CPLD's have Vccio pins, but that would be overkill for the number o...

I have been using these JTAG emulators for ADSP blackfin processors for quite some time now. I want to know about how the software breakpoint actually works internally. I opened the ADSP JTAG emulator, it had a BF531 DSP and a flash inside. Now, if my understanding is right... When we run the code in emulator mode, then the code runs from the DSP in the JTAG device. Now when i keep a breakp...

Hi, You are using GNU tools... You are searching a low cost generic JTAG solution... You are working with both LINUX and WINDOWS platform... You are coming crazy with the low-speed of the Wiggler JTAG interface... So try 'ARM Debug ValuePack' from Amontec ( www.amontec.com ). 'ARM Debug ValuePack' is fully compatible with the Raven JTAG interface. 'ARM Debug ValuePack' is 5x faster th...

Hi, in the CodeWarrior v7.2 for the Freescale hybrid 56800/E DSP series it is stated the IDE can program e.g. 56F8322 using the Motorola JTAG Parallel Port Converter (which, as this is a hobby project, I'm not very inclined to buy for > $200 and wait 4+ weeks for). One (inofficial?) schematic for the Motorola JTAG Parallel Port Converter is apparently at http://www.hc08.cz/attachment

Hello All, I am using IAR Embedded Work bench C/C++ compiler for MSP 430 devices. I would like to program the fuse of MSP430 chip using JTAG interface. I studied from MSP 430 Embedded Workbench User guide, which directed me to use the 'Secure' option in the Emulator menu after downloading the Software using JTAG interface. I downloaded the software using JTAG interface & found that the...

Hi all Is there any software available that will let me use ARM AXD debugger with a plain old Wiggler or similar home-made device? (I'm trying to debug on a device that already has a Jtag port, but not ICE). If not, are there any IP issues etc. that would prevent me from writing my own?

Hi there, We are porting a windows application from desktop into embedded Linux on Atmel AT91 ARM Cores, thus we need JTAG to debug the firmware under a Linux environment. However, SAM-ICE only connects via USB to a PC running Microsoft Windows2000 or XP. So I am looking for a JTAG emulator running on Linux. If you have any good idea/knowledge, could you please help? BTW, a frien...
