Can anyone tell me what they use for mass programming thru JTAG? In other words, I know I don't have to give the technician a wiggler and the Keil GUI to program parts. Does anyone make some kind of dongle from serial to JTAG that will work? And which software? Flash Magic? I'm looking for a simple and inexpensive method for 4-5 technicians to simply be able to program a LPC2148 with a g...

Anyone out there running the combo of Keil's compiler and JTAG with Embedded Artists 2148 board and prototype board? I have been using Philips Flash Utility to download code to the EA boards and it works perfectly. I got JTAG working several weeks ago for a couple of hours, but when I solved my problem, I went back to serially programming the flash (since I have a serial display in which ...

We ran into a similar problem on the LPC2294 (No JTAG function) and it turned out that we were inadvertently causing the micro to enter an undocumented test mode which disabled the JTAG due to a failed CAN Transceiver. In our case on the LPC2294 it was caused by holding TD1 (pin22) low at reset. Below is what we got from NXP for the LPC2294 As far as other "magic pins", here is a list...

Is it possible to establish communications with the JTAG controller of a LPC2364 while the LPC2364 RESET line (not TRST) is asserted ? This would appear to be necessary in order to debug the processor as it comes out of RESET. My (high-end) external JTAG device seems unable to accomplish this feat ... Thanks, Scott.

Hi: I seem to have a problem getting the JTAG to work on a new LPC1765 board design. I've done numerous LPC2XXX parts and never had a JTAG problem, but this is my first time with a LPC17XX. The TDO (pin 1) just seems to be stuck HI, never moves. I've tried PullUp or PullDn on the TCK and the rest have PullUp's. They are all 5K. The resets are both HI. The odd thing is the TDO has 2.2V...

hi I use ULINK with keil eval. When i debug code to toggle pins using fast io, the code works as expected in run mode, but when single stepping the pins do not follow the values they should take. Has this anything to do the way fastio connects to the internal bus, or is this a ULINK jtag bug ? I was doing this with an LPC2103 , maybe someone can try to simulate this on another JTAG d...

I am working on a small board design with an LPC236x on it, and I have run out of room for a JTAG connector. Do I need it for anything other then debugging purposes, or can I just use the serial boot loader that is built in to the chip? The chips do come with the boot loader pre-installed right? If I do need the JTAG signals for programming, what are the minimum number of signals I can get away...

Thanks Dave. Thanks particularly to TwentyOne who helped me get the settings right after receiving a wiggler-compatible from Olimex. With the latest version of h-jtag it works great for me when the jtag configuration is right. The trick was with the nSRST option - I had it = [No Sys Rst] when Wiggler (predefined) was active. When changed to = [Pin 6 D4] it detected the target and starte

It will continue running if I remove the JTAG connec...
