I am using an Ashling Vitra JTAG interface here on an Ashling EVBA7 eval board with LPC2106. I am not super familiar with the Ashling tools yet. I am trying to activate the IDLE mode to check power consumption. (When I get this working I will try Power Down mode) When I

That's the whole point. With JTAG you would be able to read the FLASH or download a new program that can read the FLASH. So that would defeat read protection! All you can do is erase everything by in-system programming over the UART. But. If you want to debug your own code that has read-protection enabled, you can set bit 2 in PINSEL2 as an early step in your code. This will switch P...

I am having some problems with IAR 5.4 and the Jlink box programing some of our boards that use the LPC2366. I can program the parts by using ISP serial mode, but not JTAG. Funny thing is that some of our boards work fine. Doesn't appear to be a CRP issue because I can erase the parts otherwise. The messages that I get from IAR are this, mostly...

Hi, I am new in this group and starting with NXP ARM controllers. My choice is LPC2366 for use in an embedded vision system for a mobile robot. The system will be using an Omnivision OV7720 CMOS image sensor. I plan to use the free GNU tool chain (Yagarto). I intend to rebuild Joern Kaipf's OOCDlink-s version 04 as an USB - JTAG Interface. Besides the JTAG interface pins also an addi...

does anyone know of a utility or driver that i can use to add a virtual lpt port (hardware accessible, not printer port) to a notebook without one? my aim would be to write some code that would read and write to this virtual lpt and have a wrapper that would in turn send and receive jtag cmds/data using the ftdi2232 and there jtag.dll thanks!

Hi everybody! Im trying to load my code into the FLASH memory of an LPC2148 via JTAG using OpenOCD. Im using Yagarto (Eclipse + OpenOCD) to do the work. There is any way to configure the OpenOCD to erase *only* the sectors of FLASH that would be filled with the code? Doing some research I found the command "flash auto_erase" on th OpenOCD pdf, but dont seems to work for me... Ac...

Hi, I have a jtag chain which includes tree CPLD and one LPC2292. I only want to programm the CPLDs. The problem is, that I have to specify all parts of the chain. So I needing a BSDL - file for the LPC2292. I could not find any usefull information at the NXP webside. I try to build tis file by my programming tool (Xilinx iMACT). It asks about Instruction Register Lenght. I have tryed se...

Hi All, I'm using an ARM Multi-ICE on a MCB2130 board (LPC2138) and debugging via gdb insight. So far, I've only been able to use the flash utility via ISP to flash the chip. The eventual product will only have a jtag connector, so I was wondering how I can flash the chip via jtag. I tried searching this list, but didn't find any posts that answered my query. Does anyone have any experi...

Hello to all, I have a problem with FatFS and i read all related post's but haven't got any luck running the FatFS with my board (i'm using SPI0). 1.problem: When I first initialize the card using a JTAG, the DSTATUS = 0x00, which is ok. If I restart the code using a JTAG the initialitation returns 0x02. But if i remove the card and repeat the initialization it returns 0x00. Any ideas. 2...

Has anyone found a way to use the Keil uLink2 JTAG interface while using FreeRTOS in the Eclipse environment? Or do I have to buy a PP JTAG interface? I am using the LPC2368 on the Keil MCB2300 as the target. Thanks. Todd Simonds Director of Engineering Armvida, LLC www.armvida.com t...@armvida.com ------------------------------------

I'm using an LPC 2138 to drive some high powered MOSFETs, sinking up to 20 amps. I'm using an Olimex USB JTAG device for programming and debugging. Everything works fine with the debugger and such. Only thing is that the motherboard went out on my laptop about a couple months ago and now the video driver just failed. Is this a co-incidence or is there a way the debugger could damage ...

Hi all, I noticed that quite a lot of people are working on JTAG tools for debugging on the LPC, but (as far as I know) there is still no-one that has written an open-source gdb stub for the LPC family. On sourceforge, there are a couple of gdb JTAG projects for arm processors, but none seem to support the ARM7TDMI-S. Existing closed-source software like OCDRemote and OCDCommandor does ...

Hi Sean, The discussion is not quite "academic" as it contains operational security assessment those in the "industry" use. JTAG implementation is hardware, can be enabled or disabled by software. [See notes on page 120 of 2294 user manual which states: "Important: LOW on P1.20 while nRESET is LOW enables pins P1.25:16 to opreate as Trace prot after reset"

I've got an Olimex LC2148 board. It and my code run fine when I use lpc2k_pgm to program and run it. No problems. However, my code doesn't run when I program it with the JTAG pod. Question #1: does openocd or the gnu linker calculate the signature for memory location 0x14 automatically ? My openocd config file has this in it: flash bank lpc2000 0x0 0x7D000 0 0 lpc2000_v2 0 12000 calc...
