I'm using Microchip's PicKit serial analyzer to find out why my I2C is playing up. The analyzer is set up to be an I2C slave and to accept external power. However, when I start communication then the PC software crashes and the Just-In-Time debugging reports a System.NullReferenceException error. I've downloaded the latest version of the software, updated the firmware in the analyzer ...

I'm not sure if posting this is a good idea. The question is posted in here, but I would like a second opinion to further help my moves on the debugging process. Feel free to ask me for more information that may help. http://www.electro-tech-online.com/micro-controllers/35071-using-pic-microcontroller-interface-d s1302-real-time-clock.html

Hi, I am working on ARM 922t, when I am trying to debug a small code say "hello world", I am getting Invalid CPU Mode debugger error upon doing single step debugging , I am using H-JTAG RDI interface. I have few Queries too.., (a) The customized board which I am using says to use MULTI ICE JTAG , but I am using winggler JTAG interface with H-JTAG RDI server!, can this create a problem? ...

Hi, I am using ECOS on ARM946. I have registered exception handlers for undefined instruction, data abort and pre-fetch abort, but i am unable to think of routine which can be useful for debugging in case of exception. I can think of printing register values of other modes to UART. Printing registers of other modes can help in finding cause of exceptions using program counter stack point...

Hello, Is there a book or website I can reference to gain a layman's view of embedded software development. I keep hearing all these words: board support package, hardware bring-up, on-chip debugging, JTAG, emulator..... I used this book to understand Electronic Design Automation and it was fabulous: http://www.amazon.com/exec/obidos/tg/detail/-/0131828290/qid=1113538214/sr=1-1/ref=sr_1...

I'm getting a freebie Atmel NGW100 Network Gateway Kit shortly, and I had a few questions. I plan to use the board to learn embedded Linux, and also learn some other OSs like FreeRTOS and uC/OS-II, and in the process build an adaptive cruise control whose software will run under all three of those OSs. Then I plan to release the whole thing to anyone who wants to build one for themselve...

Hi all, I'm debugging some intermittent problems reported by test-users of the circuits in my upcoming book, and it turns out they only have these problems when using my "short-form" connection method. The short-form method just connects parallel port lines direct to GPIOs on a microcontroller (this is for a SPI-style interface). The "long-form" method uses a more complicated circuit with ...

I work on PowerPC based Embedded Systems. Programming language is C. Cross compiler is Diab 4.2b. FYI, Windriver has purchased Diab. Along with the compiler comes a utility called ddump. This utility has the following syntax. ddump [command] file I invoke this utility as follows: ddump -D filename.elf I believe .elf stands for executable linking format. Anyways, this command means ...

Hi I decided to choose LPC21xx ARM devices as my microcontroller for small applications. I still havent found out what the cheapest and easiest way is to develop and debug. Are there any free or low cost solutions that allow jtag graphical debugging (win or linux ) ? Is there a low cost alternative to keil-ARM tools ? (The Keil Ulink Jtag and their LPC21xx based boards look a good s...

Dear all, Can an imperfect power off reset, with the power supply going down to 0.5 V instead of required 0.1 V, damage flash programmable HC08 chips? I have made a board with a micro and a RS232 line driver amongst other things, and I have been using Metrowerks to download the code. It worked ok for some time, it went to a few dozens of programming/debugging cycles, say 30, and the...

Hello, I'm working on a `gdb stub' to allow debugging of code in an Atmel AVR processor using gdb running on the host platform. Communication between gdb and the stub is done over RS232. At this moment my platform is the at90can128, but other AVR types should work as well with little change. The stub is implemented as an interrupt handler on the serial-rx interrupt. When the ISR is acti...

Hi, I have compiled linux kernel with arm-eabi toolchain on Ubuntu. The kernel is working. Now I'd like to debug it with gdb. I tried this command: arm-eabi-gdb vmlinux My questions: Which gdb should I use? There is a gdb in the arm-eabi (downloaded with android) toolchain. This will good? I have tried that but I have got Don't know how to run. Try "help target" error message. I t...

Hi all, I have spent some time on writing a simple code that works with the serial port on my embedded system (Mica2 from crossbow) that has an Atmel 128L. After debugging the code upmteeth time and with help from http://www.easysw.com/~mike/serial/serial.html, i seem to have it working with the correct baud rate being set. However, each byte that I receive in my embedded processor seems to ...

Hi, as a newbie in this area, I am wondering if I should buy the JTAGICE mkII or the AVR RISP mk II. Is it correct that the JTAGICE mkII can be used for programming *and* debugging all Atmel MCUs, even the AVR32 range?. And, is it correct that the AVRISP MKII is used *only* for programming, and it is not usable for the AVR32 microcontrollers?. Assuming the above ideas are correct, ...

Hi I want to know if Keil's ULINK2 USB-JTAG debugger can be used with Gnu ARM toolchain. Specifically, if it can be used with gdb or any linux debugger for debugging programs on Keil MCB2140 kit. Any body has any experience with it? Thanks in advance JS

I am working on a master slave architecture based on RS485 protocol in 9-bit mode (with backbone configuration). The master is 80c196kd and the slaves are all 8051 microcontrollers. The slaves are in fact sensors and actuators. Now the problem in working with 9-bit mode is that the debgging becomes tough, normaly i use MATLAB for observing the data (when in 8-bit mode). Matlab does not support...
