Happy New Year to all LPC2000 members :) During the Holidays one of our engineers tried H-JTAG and there is progress! Our tests show that H-JTAG connects just great to IAR EW-ARM (the only RDI support IDE we have at the moment) and works without any problem with our ARM-JTAG if you set in JTAG Settings nSRST = D4 (by the way while you step

I have pullups on my JTAG lines (works fine), but noticed that in the pin definitions on page 73 of the user manual that the JTAG pins already have pullups on them. Is this when they are defined as GPIO or do they have them when configured as JTAG? If I don't really need them, I want to remove my 10K pullups from my board. Sutton

Hello all! I have tried to use Keil (V.3.03) with H-JTAG server (V.0.43) and Wiggler, but I didn't have success. When I start debug mode in Keil, my Target (MCB2100) don't is update with new software. The software is starting and breakpoint don't function properly. I made my JTAG according the site H-JTAG. Can somebody help me? ...

Hi, I build the simple board with LPC2103 to start learning LPC21xx. I have success to access the serial bootloader and software download with it. Next step I build the RDI-JTAG (Wiggler type), and use H-JTAG dll with Keil Software. The Wiggler-JTAG seems to work OK, since I have success to Flash it with H-FLASHER, the H-JTAG also recognized my LPC2103. The problem come when I try the...

I am having a problem when trying to disable the JTAG interface on an LPC213X. I have a pulldown resistor attached to P0.31. On my JTAG interface, I apply 3.3V to P0.31 and everything works fine. What I have noticed, is that when my JTAG interface is not connected (p0.31 pulled low) I no longer recieve EINT0 interrupt on P0.16. Can anyone tell me if they have seen this behaviour? Or...

Hello All, im designing a weather datalogger using LPC2148 and i ran out of available GPIO pins to accomplish all the functions i need ( unless i use the JTAG pins as GPIO ). So, here is my idea on how to use the share the JTAG pins without loosing the JTAG functionality completelly (i would share the JTAG pins with my LCD control GPIO pins .) I could have a jumper on a GPIO pin. ...

I installed h-jtag and i made a wiggler jtag dongle ( http://shrani.si/files/wiggler1107820.pdf - also found on h-jtag web site). I tried to connect my lpc2138, and it doesn't work. I get "Error: Please make shure that the hardware is properly connected and powered up." But it was powerd up and connected properly (i think so). I also checked some other wiggler j-tah schematics...some of t...

Hi all, My LPC2368 won't start without the JTAG in use. When I use the JTAG to download firmware and debug there is no problems, firmware runs absolutely fine! However, when I disconnect the JTAG and leaves the CPU on it's own, then nothing happens...The firmware doesn't get executed. I have checked the reset circuit and it works fine. To get closer to the answer I tried connecting to ...

I have design my own custom Board. I have confirmed that all JTAG connections are correct and have confirmed my ULink-ME is working on a STM32 development board. I am using uVision4. Using standard Blinky project from Keil. When I tried to connect to the CPU I get JTAG Communication Failure. I have confirmed that all pull up and pull down resistors are correct on JTAG .. I have assembled a ...

Hello, We are interested in buying your JTAG code for LPC chips. The code has to be written in C++ for the parallel port JTAG from olimex. Even better, if you have code to run JTAG on the new FTDI USB chip. Your code should be able to - read/write RAM - set/clear hardware breakpoints - set/clear software breakpoints - read the pr

Greetings: I have been trying use H-JTAG to program LPC21xx FLASH without success so far. I wonder if anyone else within this group has had success with this software? I am running Windows XP SP2. My Olimex wiggler clone interface works good under my installation of Rowley's CrossWorks for ARM development system IDE however it does not work with H-JTAG. Instead of detecting the MPU on ...

JTAG is running but ... OK, I have got the JTAG stuff running fairly well. I can read the DCC registers in the EmbeddedICE and communicate with the target in this way. I also have access to the run control: I can halt the ARM code and clock instructions into the pipeline - but here is were things get messed up: After halting the core by asserting

Anyone ever had mysterious Comm failures with JTAG after long periods of being able to program successfully? I haven't had one in about 9 months, but usually reprogramming via serial port cures the problem. I have one of these annoyances now, but I can still program serially 100% of the time, but JTAG still doesn't work. I've: 1. changed and programmed 3 different CPUs serially, bu...
