Hi Could anyone recommend a cheap Jtag debugger for use with this board. I intend to use free gnu toolset for development. I have looked at the JTAG key-Tiny from Amontec and arm-usb-ocd from olimex - would either of these work? Thanks ------------------------------------

Hi I'm new to ARM processors and JTAG but have some previous experience with other micros like AVR's. I am currently trying to program my LPC2138 on my custom made board with an Olimex ARM-USB-TINY JTAG adapter. So far I've managed to get almost everything working, except for the config/script files for flashing to device with JTAG. When I tell it to program, the console outputs this: ...

Hello Community ! I'm trying to use a USB-TINY JTAG from Olimex with a custom board I made (lpc2148) using OpenOCD , but I get the message : Error validating JTAG scan chain , IR mismatach, scan returned 0x00. I tested the same board with the Olimex JTAG WIggler using LPT port and it works well, I can access it using the OCD commander and with IAR workbench, I tested the USB-TINY with...

Hello All, I have seen a lot of talk around about Wiggler-based JTAG debugger boards, which can be built for < $1, and I see several commercial JTAG debugging pods that are > $1000. What is it that these things do that you can't do with a simple wiggler interface? I.e. for most intents and purposes what can you not do with a wiggler interface?

Hello Everyone: We just started working on our first design based on the LPC2101 part. We have a Keil MDB2103 Eval Board and followed the reference design schematic for the JTAG interface which showed TCK and RTCK being pulled down. We had nothing but troubles trying to get the ULINK JTAG adapter communicating and only after we changed these 2 signals to being pull-ups did we successf...

Hello, I am newbie about ARM uCs. I have experience about uCs and i am interesting in ARM especially LPC's now. I've searched the jtags and dev. env. on google and i read some group messages but i do not know what i should buy as a jtag. I wanna focus on LPC2468 now. After that i will try an ARM9 based uC and then maybe on ARM11. Which jtag(ulink2, jlink, hlink, olimex's openocd etc.) and which...

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...

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...

Hello, I'm trying to port the Xilinx xapp058 (jtag emulator for uC) into NXP LPC2378. I modified the C code and I tryed to compile but I have the following error: jtag.axf: Error: L6224E: Could not place port.o (.data) in any Execution region. Target not created. This is due to the large size of the buffer that contain the jtag bitstream. If I decrease the buffer, for example...

I designed a small simple board using LPC2387. However, JTAG interface does not respond to my Wiggler clone. I watched the signals and found that all TDI, TMS, TRST, TCK signals are present but TDO signal coming from LPC stays high -I think it is also because of pull up resistor I placed. What might be missing? Am I missing to connect some pins to somewhere to enable the JTAG interface? O...

I just received my IAR LPC2106 KickStart kit ($149 from Philips Website), but I could not find the JLINK JTAG box. Should it come with a JTAG box or not? Anyone knows? Thanks, -martin

I'm making a board with multiple LPC2000 series chips on it. Can I somehow share one JTAG connector for all the chips or do I have to have one connector per chip if I intend to use JTAG?

Are the TRST and RTCK pins needed for JTAG on the LPC? I am programming a Xilinx CPLD without these 2 pins fine on my prototype board, but am having trouble getting the LPC to communicate with my Keil wiggler. Also, if these pins (P1.26-P1.31) are designated for a DEBUG port, does that mean TRST and RTCK pins cannot be used for anything else (if they are not needed for JTAG)? Sutton

Anyone out there running the combo of Keil's compiler and JTAG with Embedded Artists 2148 board and prototype board? I can and have been using Philips Flash Utility to download code to the EA boards and it works perfectly. However, now that I am trying to debug software, I can't seem to be able to debug using Keil's JTAG. Is there a compatibility problem? I get 'Memory Mismatch' Error...

Is it possible to have primary jtag interface enabled with acess to other i/o ports including the ports shared with ETM. In user manual there is a table that describe DBGSEL enable JTAG as well as ETM so I suppose all pins used by ETM are inaccessible for application use. I

Hi, I have designed a wiggler clone as shown in the HJTAG website. I use it to interface it with my TMS470(R1B512) microcontroller. I'm using IAR Embedded Workbench to develop my code. I initiate the H-JTAG Server, and configure IAR to an RDI interface using the H-JTAG.dll driver. Each time when i try to debug i get an this error WinRDI OpenProc failed [RDI Error: 612] Memory read/write ...

Is there any documentation that talks about the necessity of a crystal oscillator to make an LPC's JTAG work ?? LPC1768 in our case but I think I have run into this before on LPC2144. I'd just like to know if someone knows where anything mentions this requirement that for the JTAG to work, it would require a crystal or some special PLL setup to work. i.e. internal RC oscillator doe...

Recently I started laerning about ARM (LPC2148) and found Keil, IAR and Rowley GUI environments. I read their documentations and user comments and to me it seems tgat Rowley Crossworks is what suits me the best (it is not as complicated as Keil or IAR). I have some problems with JTAG Wiggler in Rowley CrossWorks 1.7. I made the JTAG Wigler clone similar to Leon's design (with 74HC244). ...
