Hi everybody- My project uses several BGA parts. We're in the second board rev stage (rev 2). Our board manufacturer doesn't seem to be able to 100% reliably solder those parts down. It makes SW debugging troublesome because one never knows if the SW or the part is misbehaving. We've had 15 boards built and I estimate 20% have BGA problems. I'd like to hear other's experiences with a...

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 recently acquired a new laptop, which (of course) has no parallel port. I've been looking into MSP430F169 board from Olimex to use in a prototyping/testing situation for an FPGA. I'm impressed with the MSP430 line, but I'd like to be able to do the device programming and debugging from my usual Linux development environment. Both TI and Olimex make USB-> JTAG programmers/debuggers

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...

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...

Hi I designed an SH3-7709 (80MHz) based industrial controller about 2 years ago, which has been used in a number of applications. This has worked fine after initial debugging and board validation etc. and has been in production now for over 18 months. Recently the contract assembly house was changed to get better quality and value, as the manufacturing volumes are beginning to grow. I...

Dear Forum Memebers I have tried but had not managed to find the 80x51 or R3000 invers assemblers for 16500b logic analyzer. I've got all the recent 16500 standard software including the SYMBOL UTILITY, but no INVERS ASSEMBLER. Currently I am finishing the debugging process of 80x5 and R3000 semi-custom cores and I really badly need thi disassemblers Does anyone have these files? I tried...

Hi guys, I'm Looking for an experienced embedded firmware C programmer to develop real-time communication and instrumentation and control firmware for a new boards. Familiarity with hardware debugging techniques will be necessary, and ability to work from less than perfect (and changing) documentation. Currently using high end PICs and Ethernet communications. FPGA familiarity wouldn't hurt...

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...

Hi all, I'm working on interfacing a custom IP core to a TSK3000 (Altium's P/H:MIPS-like soft processor) over WISHBONE bus and it seems I've run into some endianness problems. I've always been confused by endianness issues and now, after a few days of debugging both hardware and software, my head is ready to explode. The TSK3000's datasheet states that the processor uses only BIG endian ...

Hi, I'm debugging an embedded system which is supposed to be equipped with DDR2 memories. Chips are marked with "IDH22" and below with "D9LHT". The symbol on the right side is the Micron logo. I can't find such chip in the Micron website. What type of memory it is? Where can I find the datasheet? -- TIA & Regards, Wojtek

Hi, I'am trying to debugg a program loaded into a freescale M52233DEMO evaluation board. I'am starting GDB and than connects to the ev-board using the following command: target remote | m68k-elf-cfpe-stub -d USBMultilink -t m52235evb I can than communicate with the board using different GDB commands. I can view memory and register content, disassemble, set and view breakpoints. So ...

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...

Hello. I've a problem with LPC2103. I've two boards. The first-one is a Silica Demo Board with a Philips (with Philips logo) LPC2103. The second one is a home built board with only a NXP (note not Philps marked!) LPC2103 and just supplies and xtal. I've a Keil uLink and I use uVision3 for Arm. So, I can program both MCUs and everything works well. Unfortunately I can debug just only the ...

Hello,members! I want to add a debugging stub on AT91RM9200 target,I've looked at some information about it,but i don't know how to write that AT91-stub.c? Introduction is: On the host, GDB already understands how to use this protocol; when everything else is set up, you can simply use the `target remote' command . On the target, you must link with your program a few special-purpos...

For an existing motor control application, we're considering upgrading from our current ROMless ST10R167 processor to newer one with onboard flash to get faster execution. One of the main attractions of the Infineon XC16X chips is JTAG debugging, with excellent code and onboard peripheral compatibility with the C167/ST10. (Using a bond-out emulator isn't practical with our equipment.) We use ...

Hi, Just wondering if it is worth forking out for the Lauterbach debugger/ICE or to settle for something like OpenOCD + Amontec JTAGKey to debug an Atmel SAM7 MCU please? Basically I'd like to be able to set breakpoints in my IDE (Eclipse or Xemacs) and if possible, view contents of registers/RAM etc. Thanks very much. PretzelX.

Hi I am having trouble understanding RETI instruction. Being a novice at MSP430 architecture, have begun exploring by writing simple snippets. I am trying to blink a LED using a timer. I want to control the dutycycle of the flashing. My query is that after exiting the ISR on RETI, which instruction does the control flow go to. Have tried debugging via different methods but its still unclear. ...
