I am somewhat confused about debugging arm processors through the jtag port using gdb. There does not seem to be a complete GPL based option. I see alot of commercial software for which I do not have the thousands to spend on and I see bits and pieces of software that looks like it could be integrated to provide jtag debug access, but nothing fully integrated. I have experiemented with imp...

I have bought an AVR Butterfly as my first step in exploring the wonderful world of microcontrollers, and have worked out how to compile and load programs into it using WinAVR, AVR Studio and the RS232 connection. And all for ? 30! Now I want to try my hand at on board debugging. Do I just buy the JTAG dongle for ? 45 and talk through it to the Butterfly with AVR Studio? I can hardly bel...

Hi, I'm looking for some editing tools for elf/dwarf file format; or .obj file format if possible. My reason is that i need to modify some debugging information in the file. Please recommend any free/commercial tools if you happen to know. Thanks, Banh

Greetings. I'm not sure this is the appropriate forum for this query but I haven't been able to find a forum dedicated to the MSP430 port of GDB. I am using msp430-gdb GNU gdb 5.1.1 Code is compiled with msp430-gcc version 3.3 debugging options are enabled. msp430-gdb works fine except that arguments to functions can't be examined. Ie when I put a breakpoint inside a function the values i...

I recently purchased a clone Microchip PIC debugger from some Chinese importer http://www.virtualvillage.co.uk/Items/006401-001? (bad idea probably, I know). I set it all up, it programs perfectly and does a POST fine. The problem is with debugging. I hit the 'program' button on MPLAB, the PIC is programmed fine but I get an 'ICD0083' error (cannot enter the debug mode on the chip). I'v...

I would like to build my own programmer for Microchip PICs. There are many schematics on the Internet available but I can't seem to find exactly what I want. What I would like is something that provides all (or most) of the following functions: * Can program PIC18 family of devices (or all of the major PIC families if possible) * In-circuit programming (not debugging): the electronics us...

Hi I have an input pin that I suspect is pulled to the wrong state due to noise. I have no way to measure the pin since it's burried in inner layers of the PCB The pin frequency is max 100kHz and I have input filtering (derived from the CPU clock frequency) on the pin so I know the frequency is lower than about 10MHz So I have two ways forward: 1: Make a loop to capture the input p...

Hi All, I have written a CAN driver for star12 controller. And I do have some periodic frames for transmission. I am using not any commercial RTOS but I do have created my own scheduler for the scheduling different tasks. I am using a debugger for software download & debugging and I am also using vector CANalyzer for monitoring the CAN frames on the bus. Now the problem which I am facing i...

Hello all. I am running IAR embedded workbench software debugger through a J-Link connector to a TI TMS470. I am getting an error, "Failed to read current instruction" in a J-Link pop-up window when I try stepping through the code. After this, it will not let me continue through the rest of the code. I tried debugging in Simulator mode and I do not get this error. Has anybody ever encoun...

Hello, I am working on a project using the i.MX21 processor having the ARM926EJ-S core. The processor contains the USB controller on chip. The board also has a JTAG interface for debugging. My current problem is that, I need to write a small basic driver to check if the USB sub-system is working on my hardware. Now need to use two USB ports of my development station (Windows PC) ...

I got PIC32 starter kit today. Here are some impressions: - Comes with eval version of C32 C-compiler with 64KB code size limit. C32 is actually called C32-gcc, so it's a gcc derivative. The source is on the website, but who knows if it's recent or complete. - Hardware debugging (breakpoints, goto cursor) works in MPLAB on this little board, but I found that sometimes it gets int...

Hi, it appears funny but interesting. I am debugging a problem and for which I am using TRACE32 JTAG interface on ARM platform. But when I try to run system without attaching JTAG it crashing where as at the same time once i mount it on JTAG it runs smoothly I observed that JTAG introduces some delay so i introduced some delays at specific locations but still it is same ...

Hello All, I am using IAR C/C++ compiler for MSP430. In the project I am sending some data through MSP430 to another chip through I2C.I have made MSP430 as slave. While debugging I want to change manually the contains of I2CRB through register window,but its not allowing me to do,again the contains will come to its default value. I found in the header file supplied with the IAR package of MS...

I've been programming in C for the best part of a decade now but it's only within the last year that I've really started doing embedded systems programming. When I did C programming for a personal computer, I commonly debugged my code simply by putting in printf statements around the place to check variable values, and also by using the instrument that lets you check the values of variab...

Hi all, I m using SH7705(Reneasas,Hitachi) processor for my device.I need to have a debugger for debugging.I have found BITRAN and JH600 advicePOCKET supports this. I need to know whether JH600 advicePOCKET supports for English language also. I m from India, any idea on vendors from India or from abroad who provides these debuggers. It will be of great help. Thanks Hari

Hi, I am using a spartan 3 xc3s4000 FPGA in my custom design which is interfaced with national gigabit PHYs DP83865dvh. It is actually an Ethernet mac and the design is like this: PHY A FPGA PHY B The problem is that sometimes, not always, i get one or two packet drops when i put the systems on test. I tested only one unit using chariot for throughput, no packet drops. But when i

Hi, I am faced with a problem of not being able to effectively debug what i am doing. Is it possible to save debug information at locations in memory/flash and then examine them later ? Instead of say printing to the console, printing to locations in memory. Thanks - Nived --------------------------------------- Posted through http://www.EmbeddedRelated.com
